Patent number: 11670299Abstract: A system processes audio data to detect when it includes a representation of a wakeword or of an acoustic event. The system may receive or determine acoustic features for the audio data, such as log-filterbank energy (LFBE). The acoustic features may be used by a first, wakeword-detection model to detect the wakeword; the output of this model may be further processed using a softmax function, to smooth it, and to detect spikes. The same acoustic features may be also be used by a second, acoustic-event-detection model to detect the acoustic event; the output of this model may be further processed using a sigmoid function and a classifier. Another model may be used to extract additional features from the LFBE data; these additional features may be used by the other models.Type: GrantFiled: May 17, 2021Date of Patent: June 6, 2023Assignee: Amazon Technologies, Inc.Inventors: Ming Sun, Thibaud Senechai, Yixin Gao, Anish N. Shah, Spyridon Matsoukas, Chao Wang, Shiv Naga Prasad Vitaladevuni

Patent number: 11308939Abstract: A system and method performs wakeword detection and automatic speech recognition using the same acoustic model. A mapping engine maps phones/senones output by the acoustic model to phones/senones corresponding to the wakeword. A hidden Markov model (HMM) may determine that the wakeword is present in audio data; the HMM may have multiple paths for multiple wakewords or may have multiple models. Once the wakeword is detected, ASR is performed using the acoustic model.Type: GrantFiled: September 25, 2018Date of Patent: April 19, 2022Assignee: Amazon Technologies, Inc.Inventors: Yixin Gao, Ming Sun, Varun Nagaraja, Gengshen Fu, Chao Wang, Shiv Naga Prasad Vitaladevuni

Publication number: 20210398533Abstract: A system and method performs multilingual wakeword detection by determining a language corresponding to the wakeword. A first wakeword-detection component, which may execute using a digital-signal processor, determines that audio data includes a representation of the wakeword and determines a language corresponding to the wakeword. A second, more accurate wakeword-detection component may then process the audio data using the language to confirm that it includes the representation of the wakeword. The audio data may then be sent to a remote system for further processing.Type: ApplicationFiled: June 28, 2021Publication date: December 23, 2021Inventors: Yixin Gao, Ming Sun, Jason Krone, Shiv Naga Prasad Vitaladevuni, Yuzong Liu

Patent number: 10460729Abstract: A method for selective transmission of audio data to a speech processing server uses detection of an acoustic trigger in the audio data in determining the data to transmit. Detection of the acoustic trigger makes use of an efficient computation approach that reduces the amount of run-time computation required, or equivalently improves accuracy for a given amount of computation, by using a neural network to determine an indicator of presence of the acoustic trigger. In some example, the neural network combines a “time delay” structure in which intermediate results of computations are reused at various time delays, thereby avoiding computation of computing new results, and decomposition of certain transformations to require fewer arithmetic operations without sacrificing significant performance.Type: GrantFiled: June 30, 2017Date of Patent: October 29, 2019Assignee: Amazon Technologies, Inc.Inventors: Ming Sun, Aaron Lee Mathers Challenner, Yixin Gao, Shiv Naga Prasad Vitaladevuni
