Abstract: Audio signals produced by microphones can be processed to remove echo and reverberation. The processed signals can be mapped to each other with adaptively estimated impulse responses. One or more of the processed signals, one or more of the mapped signals, and one or more of the impulse responses can be fed to an automatic speech recognizer (ASR) having a deep neural network (DNN), to train the DNN or recognize speech in the input audio signals. Other aspects are described and claimed.

Abstract: Systems and processes are disclosed for virtual assistant request recognition using live usage data and data relating to future events. User requests that are received but not recognized can be used to generate candidate request templates. A count can be associated with each candidate request template and can be incremented each time a matching candidate request template is received. When a count reaches a threshold level, the corresponding candidate request template can be used to train a virtual assistant to recognize and respond to similar user requests in the future. In addition, data relating to future events can be mined to extract relevant information that can be used to populate both recognized user request templates and candidate user request templates. Populated user request templates (e.g., whole expected utterances) can then be used to recognize user requests and disambiguate user intent as future events become relevant.

Abstract: A speech recognition system uses, in one embodiment, an extended phonetic dictionary that is obtained by processing words in a user's set of databases, such as a user's contacts database, with a set of pronunciation guessers. The speech recognition system can use a conventional phonetic dictionary and the extended phonetic dictionary to recognize speech inputs that are user requests to use the contacts database, for example, to make a phone call, etc. The extended phonetic dictionary can be updated in response to changes in the contacts database, and the set of pronunciation guessers can include pronunciation guessers for a plurality of locales, each locale having its own pronunciation guesser.

Abstract: A method of performing automatic speech recognition (ASR) using end-pointing markers generated using accelerometer-based voice activity detector starts with a voice activity detector (VAD) generating an accelerometer VAD output (VADa) based on data output by at least one accelerometer that is included in at least one earbud. The at least one accelerometer to detect vibration of the user's vocal chords. A voice processor detects a speech signal based on acoustic signals from at least one microphone. An end-pointer generates the end-pointing markers based on the VADa output and an ASR engine performs ASR on the speech signal based on the end-pointing markers. Other embodiments are also described.

Abstract: A method for updating an adaptive speech recognition model is provided. In some implementations, the method is performed at a communications device including one or more processors and memory storing instructions for execution by the one or more processors. The method includes determining that a first user of a first mobile communication device is engaged in a call over a communications network and providing an adaptive speech recognition model The method also includes analyzing an outbound audio channel of the first mobile communication device to obtain a call audio signal corresponding to audio input from one or more microphones of the first mobile communication device and updating the adaptive speech recognition model with training data derived from the call audio signal.

Abstract: Techniques for providing reminders based on social interactions between users of electronic devices are described. Social reminders can be set to trigger based on social interactions of users. For example, a user may request to be reminded to discuss a certain discussion topic with a particular phonebook contact, when the user next encounters the contact.

Abstract: In some implementations, a user device can personalize a media stream by converting notifications into audio speech data and presenting the audio speech data at locations within the media stream that do not interrupt the enjoyment of the media stream by the user. In some implementations, the user device can receive notifications from various communication services, applications installed on the user device, and/or other sources, determine information describing the notifications, and present the information to the user using the audio speech data. In some implementations, the user device can generate personalized notifications based on the media stream and/or media items selected by the user. The user device can generate personalized notifications based on the user's context (e.g., environment, location, activity, etc.). The personalized notifications can then be presented to the user using audio speech data at appropriate locations in the media stream.
