DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0021] While this technology is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail several specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the technology and is not intended to limit the technology to the embodiments illustrated.

[0022] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms "a", an and the are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

[0023] It will be understood that like or analogous elements and/or components, referred to herein, may be identified throughout the drawings with like reference characters. It will be further understood that several of the figures are merely schematic representations of the present technology. As such, some of the components may have been distorted from their actual scale for pictorial clarity.

[0024] The present technology provides hardware and software components that interact interpret and respond to human spoken audio. In some embodiments, the hardware components include a microphone that receives audio comprising human spoken audio. The audio that comprises human spoken audio may in some instances be transmitted to a cloud computing cluster (e.g., cloud-based computing environment for processing. In general, a cloud-based computing environment is a resource that typically combines the computational power of a large grouping of processors and/or that combines the storage capacity of a large grouping of computer memories or storage devices. For example, systems that provide a cloud resource may be utilized exclusively by their owners; or such systems may be accessible to outside users who deploy applications within the computing infrastructure to obtain the benefit of large computational or storage resources.

[0025] The cloud may be formed, for example, by a network of web servers, with each web server (or at least a plurality thereof) providing processor and/or storage resources. These servers may manage workloads provided by multiple users (e.g., cloud resource customers or other users). Typically, each user places workload demands upon the cloud that vary in real-time, sometimes dramatically. The nature and extent of these variations typically depend on the type of business associated with the user.

[0026] With respect to the present technology, the audio commands that comprise human spoken audio may be processed to clarify the human spoken audio components from other audio aspects that may have also been recorded, such as background noise. In some instances, the present technology may utilize digital signal process beam-forming microphone assembly, which is included in an end user device. In other embodiments, various digital signal processes may be utilized at the cloud level to remove background noise or other audio artifacts. The processed human spoken audio may then be transmitted to a text processor. The text processor uses speech-to-text software (such as from Nuance.RTM.) and converts the human spoken audio into a string of text that represents the human spoken audio (hereinafter, "string of text").

[0027] Once the human spoken audio has been processed into a string of text, the text processor may then return the string of text to a processing server, which then transmits the string of text to a natural language processor. The terms "natural language processor" may include, but is not limited to any system, process, or combination of systems and methods that evaluate, process, parse, convert, translate or otherwise analyze and/or transform natural language commands. For example, an exemplary natural language processor may convert natural language content from an audio-format into a text format (e.g., speech to text), and may also evaluate the content for sentiment, mood, context (e.g., domain), and so forth. Again, these natural language commands may include audio format and/or text format natural language content, as well as other content formats that would be known to one of ordinary skill in the art.

[0028] At the natural language processor, the string of text may be broken down into formal representations such as first-order logic structures that contain contextual clues or keyword targets. These contextual clues and/or keyword targets are then used by a computer system to understand and manipulate the string of text. The natural language processor may identify the most likely semantics of the string of text based on an assessment of the multiple possible semantics which could be derived from the string of text.

[0029] It will be understood that in some embodiments, one or more of the features described herein such as noise reduction, natural language processing, speech-to-text services (and vice versa), text parsing, and other features described herein may be executed at the device level (e.g., on the intelligent assistant device). In other instances, many or all of the aforementioned features may be executed at the cloud level, such that the intelligent assistant device receives audio commands and returns responses. Thus, most or all of the processing of the audio commands may occur at the cloud level. In some instances, the intelligent assistant device and the cloud may share processing duties such that the intelligent assistant device executes some of the features of the present technology and the cloud executes other processes. This cooperative content processing relationship between the intelligent assistant device and the cloud may function to load balance the duties required to process audio commands and return responses to the end user.

[0030] Based on the computer system's understanding of the semantics of the string of text, data from the string of text will be prepared for delivery to an appropriate application program interface (API). For example, a string of text comprising the query, "What's the weather look like today in Los Angeles, Calif.?" may be processed by the computer system and distributed to a weather API. Further, the weather API may process the data from the string of text to access a weather forecast for Los Angeles, Calif. associated with the day that the query was asked.

[0031] Since APIs may have different data structure requirements for processing queries, one aspect of the natural language processor may be formatting the data from the string of text to correspond to the data structure format of an API that has been determined to be appropriate.

[0032] Once an API has processed the query data derived from human spoken audio, an API response may be generated. This API response may then be converted into an appropriate pre-spoken text string, also referred to as a fulfillment. Further, the API response may be recorded in a database and then converted to a speech response. Once the API response has been converted to a speech response, the speech response may be distributed to a hardware component to playback the API speech response. The API response may also be saved and/or paired with the query data and saved in a cache for efficient lookup. That is, rather than processing the same query data multiple times, the present technology may obtain previously generated responses to identical or substantially identical query data from the cache. Temporal limitations may be placed upon the responses stored in the cache. For example, responses for queries regarding weather may be obtained from the cache only for relevant periods of time, such as an hour.

[0033] In some embodiments, a hardware unit (e.g., intelligent assistant device) may act as a base station that is connected over a Wi-Fi network to both the natural language processor as well as other enabled devices. For instance, other enabled devices may act as a microphone, transmitting human spoken audio via the base station to the natural language processor or transmitting human spoken audio directly to the intelligent assistant device and then to the natural language processor. Additionally, enabled devices may also receive commands from a general server based on interpretation of the human spoken data using the natural language processor. For instance, a Wi-Fi enabled thermostat may receive a command from the base station when the natural language processor has interpreted human spoken audio to request an increase in temperature within a room controlled by the user device that received the human spoken audio data. In some instances, the intelligent assistant device may utilize other communication media including, but not limited to, Bluetooth, near field communications, RFID, infrared, or other communicative media that would be known to one of ordinary skill in the art with the present disclosure before them.

[0034] In accordance with the discussion above, FIG. 1 is a system 100 for processing human spoken audio, in accordance with embodiments of the present invention. In particular, a user spoken question or command 105 is received at microphone 110. The user spoken question or command is within audio data. As such, the audio data comprises human spoken audio. The audio data may then be transmitted to hardware device 115 (such as an intelligent assistant device) or connected hardware device 120, such as a cellular phone or digital music player. If the audio data is transmitted to connected hardware device 120, the audio data may then be further transmitted to hardware device 115 after being received at connected hardware device 120. Alternatively, hardware device 115 may comprise microphone 110 such that hardware device 115 is able to record user commands and distribute recorded user commands to a speech and text system for initial processing.

[0035] From hardware device 115, audio 125 and user identification information 130 are transmitted to a server 135, also referred to a command processing server. The audio may be cleaned at the server 135. In particular, a combination of a microphone array (e.g., using audio captured by multiple microphones), beam-forming, noise-reduction, and/or echo cancellation system may be used to clean up the audio received to remove audio characteristics that are not human spoken audio. Once audio is received at the server 135, the audio is provided to a speech-to-text service 140.

[0036] At the speech-to-text service 140, the audio is converted to a string of text that represents human spoken audio. In embodiments, the string of text may be stored in a database 142. In particular, database 142 may be used for storage of user data and for the storage of processed queries. Further, database 142 may be used to manage learned behaviors based on unique hardware identification.

[0037] The string of text may then be transmitted to a natural language processor 145. Natural language processor 145 may parse unstructured text documents and extract key concepts such as context, category, meaning, and keywords. Additionally, the natural language processor 145 may comprise artificial intelligence (AI) logic to process the string of text into a discernible query. Further, natural language processor 145 may utilize machine learning and/or a neural network to analyze the string of text. For example, natural language processor 145 may utilize a method of interpreting and learning from patterns and behaviors of the users and attributing data to such behaviors.

[0038] Further, natural language processor 145 may be run using a server system used to run natural language processor 145 and a neural network. Additionally, the natural language processor 145 may determine which query API 150 is most appropriate to receive the query associated with the string of text. Further, once a query API 150 is determined, the natural language processor 145 may modify the query to comply with the structure of queries appropriate to the determined query API 150.

[0039] The query generated at the natural language processor 145 is then provided to a query API 150. An exemplary API may comprise a variety of open source or licensed APIs that are used to take natural language processor output and retrieve the necessary data. The query API 150 processes the query and provides a query response to server 135. Once the query response is received at server 135, the query response may be transmitted to a format response component 155. The format response component 155 may comprise, for example, a text-to-speech translator. In particular, a text-to-speech translator may comprise a system used to take the national language processor output in text format and output in spoken audio. The answer 160 may then be provided to hardware device 115, such as via a device interface comprising a process of returning the spoken audio, from the text-to-speech component to hardware device 115. From hardware device 115, the answer may be transmitted through a speaker 165 to a system spoken audio response 170.

[0040] FIG. 2 illustrates a flowchart for processing human spoken audio, in accordance with embodiments of the present invention. At 202, a customer speaks a first trigger command, "Hello, ivee." It will be understood that the trigger command may be end user defined. At 204, a microphone captures the first trigger command, which may then be transmitted to device 210. The first trigger command may also be referred to as an initiating command. An initiating command may prompt the device to ready itself for a subsequent audio command.

[0041] In another embodiment, a customer speaks a second trigger command (also referred to as an audio command) such as, "Weather Los Angeles," at 206. In some instances, the audio command may comprise a natural language or spoken word command, such as the audio command at 206. The second trigger command is captured at 208 by one or more microphones and transmitted to device 210. Device 210 is coupled with a private API 230 via WiFi connection 222. Further, device 210 provides an audio query 224 to private API 230. In particular, audio query 224 is derived from an audio command.

[0042] Audio query 224 may then be provided to a speech/text processor 232, which translates the audio query 224 into text query "Weather Los Angeles" 226. Text query "Weather Los Angeles" 226 is then provided to private API 230, which directs text query "Weather Los Angeles" 226 to an AI Logic component 234. AI Logic component 234 then provides text query "Weather Los Angeles" 226 to a third party API 236. For example, for the text query "Weather Los Angeles" 226, an appropriate third party API 236 may be a weather API. Third party API 236 then generates text answer "76 Degrees" 228.

[0043] Text answer "76 Degrees" 228 may then be provided to AI Logic component 234. Further, text answer "76 Degrees" 228 may then be transmitted from AI Logic component 234 to private API 230. Further, text answer "76 Degrees" 228 is provided to a speech/text processor 232 where text answer "76 Degrees" 228 is translated to audio answer 238. Audio answer 238 may then be provided to private API 230 and then provided to device 210. From device 210, audio answer 238 is output as an audio "76 Degrees" 240. In particular, audio response "76 Degrees" 240 is in response to audio command "Weather Los Angeles" 204. Further, audio "Command Please" 242 is in response to the initiating command "Hello, ivee" 202.

[0044] FIG. 3 illustrates a display 300 of interactions utilizing a device command interpreter 305, in accordance with embodiments of the present invention. For example, device command interpreter 305 interacts with an interface with a device 310. In particular, device command interpreter 305 receives a command from the interface with the device 310. Device command interpreter 305 also provides commands to the interface with the device 310. Further, device command interpreter 305 interacts with a text/speech processor 325. In particular, device command interpreter 305 may provide a request for text-to-speech translation by providing a string of text to a text-to-string ("TTS") component 315 of the text/speech processor 325. Additionally, device command interpreter 305 may provide a request for speech-to-text translation by providing a voice file to a speech-to-text component 320 of the text/speech processor 325. Further, device command interpreter 305 may receive scenario information from scenario building component 330.

[0045] Additionally, device command interpreter 305 is also communicatively coupled with language interpreter 335. In particular, device command interpreter 305 may provide a sentence with scenario information to language interpreter 335. Further, the language interpreter 335 may generate analyzed sentence information and send the analyzed sentence information with scenario information to a decision making engine 340. The decision making engine 340 may select a most appropriate action. Further, the decision making engine 340 may utilize user accent references from a voice database 345. Based on the analyzed sentence information and the scenario information, the decision making engine 340 may generate a selected most appropriate action from scenarios and, further, may provide the selected most appropriate action to the device command interpreter 305.

[0046] The device command interpreter 305 may also send a request to build sentence information to a sentence generator component 350. In response, the sentence generator component 350 may provide a built sentence string to device command interpreter 305. Additionally, the device command interpreter 305 may request service on servers by providing a service request to an add on service interface 355. The add on service interface 355 may provide the service request to a voice database web server 360. Further, a response generated by voice database web server 360 may be provided to the device command interpreter 305 via the add on service interface 355.

[0047] Further, device command interpreter 305 may interact with a user database 370 via a user information database 365. In particular, device command interpreter 305 may provide user information and device authentication to the user database 370 via an interface of the user information database 365. Additionally, device command interpreter 305 may interact with a streaming interface 380 of a device via communications module 375. In particular, device command interpreter 305 may provide a file for download and/or text-to-speech voice data to file downloader. Communications module 375 may include any data communications module that is capable of providing control of data streaming processes to the streaming interface 380 of the device. In response, the streaming interface 380 of the device may provide a data stream to communications module 375. The communications module 375 may provide a voice streaming up of device command interpreter 305.

[0051] FIG. 9 provides a block diagram 900 of components of an intelligent assistant device, in accordance with embodiments of the present invention. In particular, FIG. 9 comprises microphones 902 which provide audio data to an audio processor module 904. Audio processor module 904 provides analog data to a sensory natural language processor 906. Further, audio processor module 904 provides an analog or SPI (Serial Peripheral Interface) signal to a processor 908, where processor comprises a main Atmel chip. Further, light sensor 910 and temperature sensor 912 also provide data to processor 908. Buttons and/or switches 914 also provide data to processor 908 via a touch sensor controller 916. Additionally, data processor 908 is communicated between processor 908 and sensory natural language processor 906. Sensory natural language processor 906 is also coupled with an external memory for firmware 918.

[0052] Processor 908 also exchanges information with a Fast Super-Twisted Nematic Display (FSTN) Liquid Crystal Display (LCD) display module with driver 920, as well as a WiFi module 922. Further, processor 908 is communicatively coupled with an Erasable Programmable Read-Only Memory (EEPROM) 924 for user information and/or settings. Processor 908 is also communicatively coupled with radio module 926 and audio mux 928. Audio mux 928 is an audio amplifier chip. Audio mux 928 also receives data from aux audio input 930.

FIG. 9 also comprises, for example, a USB Jack (or other similar communicative interface) for recharging 936 that provides rechargeable battery 938.

[0053] In addition to the embodiments described above, another exemplary embodiment may utilize a plurality of microphones of a smartphone base to implement a natural language processor, in accordance with embodiments of the present invention. In particular, audio is received at the plurality of microphones at a smartphone base. The audio is received at an application running a natural language processor, such as natural language processor 145. Further, the application comprises a clean-up component that utilizes a combination of a microphone array, beam-forming, noise-reduction, and/or echo cancellation system to clean up the audio received. In particular, the clean-up component may remove non-human spoken audio and/or may remove garbled human spoken audio (e.g., background conversations) that do not comprise primary human spoken audio (e.g., the human spoken audio of the primary user). By using this process, a user can interact with a smartphone application from approximately ten feet away and closer. As such, by using audio clean-up processes such as beamforming, audio received from microphones of auxiliary hardware devices, such as a dock for smartphone devices, may be used to interact with an application that comprises a natural language processor, such as natural language processor 145.

In FIG. 12A, an intelligent assistant device 1200 may be communicatively coupled with various systems through a client API 1205. More specifically, the intelligent assistant device 1200 may communicatively couple with a speech processor 1210 of FIG. 12B, which in turn, couples with an external speech recognition engine 1215, in some instances. Again, the intelligent assistant device 1200 may include an integral speech recognition application.

[0057] A frames scheduler may be utilized to schedule and correlate responses with other objects such as advertisements.

[0058] The intelligent assistant device 1200 may also communicatively couple with a notifications server 1220 as shown in FIG. 12C. The notifications server 1220 may cooperate with the frames scheduler and an advertisements engine to query relevant advertisements and integrate the same into a response, which is returned to the intelligent assistant device 1200.

[0059] As shown in FIG. 12D, the system may utilize a command fulfiller 1225 that creates API requests and processes responses to those requests. Additionally, the command fulfiller 1225 may also generate return response objects. The command fulfiller 1225 may communicatively couple with the speech processor 1210 of FIG. 12B, as well as various sub-classes of command fulfillers 1230. These sub-classes of command fulfillers 1230 may query third party information sources, such as an external knowledge engine 1235.
