20140302895 | METHOD OF CONTROLLING DIALING MODES IN A VEHICLE - A dialing mode of a telematics unit in a vehicle is controlled by monitoring for dialing digits from a vehicle occupant, determining whether the type of dialing digits are continuous dialing digits or discrete dialing digits, establishing a continuous mode for receiving continuous dialing digits or a discrete mode for receiving discrete dialing digits based on the determination, and if the type of dialing digits changes, switching the established mode. | 10-09-2014 |
20150248881 | DYNAMIC SPEECH SYSTEM TUNING - A system and method of tuning speech recognition systems includes performing text-to-speech conversion of text data; detecting the accuracy of speech converted from text data; determining that the detected accuracy is below a predetermined threshold; recording a user recitation of the text data in response to the determination; and storing the user recitation in an exception database located at a vehicle. | 09-03-2015 |
20150255063 | DETECTING VANITY NUMBERS USING SPEECH RECOGNITION - A method of detecting vanity numbers using an automatic speech recognition (ASR) system includes wirelessly downloading data from a vanity number database into a vehicle; storing the uploaded data in an ASR model at the vehicle; and receiving speech input from a vehicle occupant at the vehicle; cross-referencing phonewords detected from the received speech with content from the ASR model. | 09-10-2015 |
20150264480 | PROCESSING OF AUDIO RECEIVED AT A PLURALITY OF MICROPHONES WITHIN A VEHICLE - A method of processing audio received at a plurality of microphones in a vehicle includes receiving the audio as a first audio stream and second audio stream at respective first and second microphones that are positioned at different locations within the vehicle; creating a first digital time series and a second digital time series that represent the first audio stream and the second audio stream, respectively; calculating a delay that exists between the first audio stream and the second audio stream based on a cross-correlation of the first digital time series and the second digital time series; and processing the received audio using the calculated delay. | 09-17-2015 |
20150302851 | GESTURE-BASED CUES FOR AN AUTOMATIC SPEECH RECOGNITION SYSTEM - A method of recognizing continuous digits uttered by a speaker using an automatic speech recognition (ASR) system includes receiving continuous digits via a microphone as speech from a user; detecting that recognition of one or more of the continuous digits falls below a predetermined confidence threshold; prompting the user to identify the continuous digits using a body gesture; detecting the body gesture made by the user; and identifying one or more of the continuous digits based on the body gesture. | 10-22-2015 |
20150341005 | AUTOMATICALLY CONTROLLING THE LOUDNESS OF VOICE PROMPTS - A system and method of regulating automatic speech recognition (ASR) playback of audible prompts includes: generating an audible prompt via a speaker; detecting ambient sound during the audible prompt via a microphone; obtaining a speech recognition confidence value for speech recognition performed on the ambient sound; and reducing a volume level of the audible prompt based on the speech recognition confidence value while continuing to generate the audible prompt. | 11-26-2015 |
20160039356 | ESTABLISHING MICROPHONE ZONES IN A VEHICLE - A system and method of activating at least some of a plurality of microphones in a vehicle includes: identifying an acoustic zone within the vehicle where a vehicle occupant is located; detecting one or more biometric attributes of the vehicle occupant; determining a location within the acoustic zone where the vehicle occupant utters speech based on the detected biometric attributes; and activating a subset of the plurality of microphones in the vehicle to receive speech within the acoustic zone based on the determined location. | 02-11-2016 |
20160071509 | TEXT-TO-SPEECH PROCESSING BASED ON NETWORK QUALITY - A method is disclosed that provides text-to-speech (TTS) functionality to a telematics unit of a telematics-equipped vehicle. The method includes: receiving text content to be played back by an audio system of the telematics-equipped vehicle; determining, by a processor, a TTS rendering process to be used for the text content from a plurality of TTS rendering processes, wherein the plurality of TTS rendering processes include local TTS rendering using a local TTS engine at the telematics-equipped vehicle and remote TTS rendering using a remote TTS engine at a communications center; and causing, by the processor, the text content to be rendered as an audio signal for playback by the telematics-equipped vehicle using the determined TTS rendering process. | 03-10-2016 |
20160111090 | HYBRIDIZED AUTOMATIC SPEECH RECOGNITION - A system and method of providing speech received in a vehicle to an automatic speech recognition (ASR) system includes: receiving speech at the vehicle from a vehicle occupant; providing the received speech to a remotely-located ASR system and a vehicle-based ASR system; and thereafter determining a confidence level for the speech processed by the vehicle-based ASR system; presenting in the vehicle results from the vehicle-based ASR system when the determined confidence level is above a predetermined confidence threshold is not above; presenting in the vehicle results from the remotely-located ASR system when the determined confidence level is not above a predetermined confidence threshold. | 04-21-2016 |
