20130144618 | METHODS AND ELECTRONIC DEVICES FOR SPEECH RECOGNITION - A disclosed embodiment provides a speech recognition method to be performed by an electronic device. The method includes: collecting user-specific information that is specific to a user through the user's usage of the electronic device; recording an utterance made by the user; letting a remote server generate a remote speech recognition result for the recorded utterance; generating rescoring information for the recorded utterance based on the collected user-specific information; and letting the remote speech recognition result rescored based on the rescoring information. | 06-06-2013 |
20130218573 | VOICE COMMAND RECOGNITION METHOD AND RELATED ELECTRONIC DEVICE AND COMPUTER-READABLE MEDIUM - An electronic device for browsing a document is disclosed. The document being browsed includes a plurality of command-associated text strings. First, a text string selector of the electronic device selects a plurality of candidate text strings from the command-associated text strings. Afterward, an acoustic string provider of the electronic device prepares a candidate acoustic string for each of the candidate text strings. Thereafter, a microphone of the electronic device receives a voice command. Next, a speech recognizer of the electronic device searches the candidate acoustic strings for a target acoustic string that matches the voice command, wherein the target acoustic string corresponds to a target text string of the candidate text strings. Finally, a document browser of the electronic device executes a command associated with the target text string. | 08-22-2013 |
20130304478 | SPEAKER AUTHENTICATION METHODS AND RELATED METHODS AND ELECTRONIC DEVICES - An embodiment of the invention provides a method of preparing for speaker authentication. The method includes: receiving speech data that represents an utterance made by a user; extracting side information; examining the side information to determine whether to allow speaker model training using the speech data; and generating a feedback message for the user based on the side information if speaker model training using the speech data is not allowed. | 11-14-2013 |
20140075570 | METHOD, ELECTRONIC DEVICE, AND MACHINE READABLE STORAGE MEDIUM FOR PROTECTING INFORMATION SECURITY - An embodiment of the invention provides an electronic device. The electronic device is configured to protect a set of private data of an authorized user of the electronic device. The electronic device includes a biometric sampler, a biometric authenticator, and a data provider. The biometric sampler is configured to covertly collect a set of biometric samples from a current user of the electronic device. The biometric authenticator is configured to covertly use the set of biometric samples of the current user and a set of biometric data of the authorized user to verify whether the current user is the authorized user. The data provider is configured to give the current user access to a set of fake data instead of the set of private data if the current user is not the authorized user. | 03-13-2014 |
20140146972 | MICROPHONE SYSTEM AND RELATED CALIBRATION CONTROL METHOD AND CALIBRATION CONTROL MODULE - An embodiment of the invention provides a calibration control method performed by a microphone system. The microphone system includes a plurality of microphones configured to generate a plurality of microphone signals. First, the microphone system equalize the microphone signals to generate a plurality of equalized microphone signals. Next, the microphone system calculates a set of similarity indicators based on the equalized microphone signals. Then, the microphone system compares the set of similarity indicators with a set of predetermined thresholds to determine whether to calibrate the microphone signals. | 05-29-2014 |
20150073799 | VOICE VERIFYING SYSTEM AND VOICE VERIFYING METHOD - A voice verifying system, which comprises: a microphone, which is always turned on to output at least one voice signal; a speech determining device, for determining if the voice signal is valid or not according to a reference value, wherein the speech determining device passes the voice signal if the voice signal is valid; and a verifying module, for verifying a speech signal generated from the voice signal and for outputting a device activating signal to activate a target device if the speech signal matches a predetermined rule; and a reference value generating device, for generating the reference value according to speech signal information from the verifying module. | 03-12-2015 |
20150161989 | SYSTEM FOR SPEECH KEYWORD DETECTION AND ASSOCIATED METHOD - The invention provides a system for speech keyword detection and associated method. The system includes a speech keyword detector, an activity predictor and a decision maker. The activity predictor obtains sensor data provided by a plurality of sensors, and processes the sensor data to provide an activity prediction result indicating a probability for whether a user is about to give voice keyword. The decision maker processes the activity prediction result and a preliminary keyword detection result of the speech keyword detection to provide a keyword detection result. | 06-11-2015 |
20150365750 | Activating Method and Electronic Device Using the Same - An electronic device includes a receiver and an activator. The receiver includes a microphone; and a signal detector, coupled to the microphone, for determining whether a valid input signal received from the microphone is a voice signal or an ultrasonic signal by comparing a frequency of the valid input signal with at least two frequency bands, and accordingly passing the valid input signal. The activator includes a voice detection module, for performing a voice activated process; and an ultrasonic detection module, for performing an ultrasound activated process. The voice detection module and the ultrasonic detection module are enabled by the signal detector simultaneously or separately. | 12-17-2015 |
