Publication number: 20200312315Abstract: An acoustic environment aware method for selecting a high quality audio stream during multi-stream speech recognition. A number of input audio streams are processed to determine if a voice trigger is detected, and if so a voice trigger score is calculated for each stream. An acoustic environment measurement is also calculated for each audio stream. The trigger score and acoustic environment measurement are combined for each audio stream, to select as a preferred audio stream the audio stream with the highest combined score. The preferred audio stream is output to an automatic speech recognizer. Other aspects are also described and claimed.Type: ApplicationFiled: March 28, 2019Publication date: October 1, 2020Inventors: Feipeng Li, Mehrez Souden, Joshua D. Atkins, John Bridle, Charles P. Clark, Stephen H. Shum, Sachin S. Kajarekar, Haiying Xia, Erik Marchi

Patent number: 10789041Abstract: Systems and processes are disclosed for dynamically adjusting a speech trigger threshold, which can be used in triggering a virtual assistant. Audio input can be received via a microphone. The received audio input can be sampled, and a confidence level can be determined of whether the sampled audio input includes a portion of a spoken trigger. In response to the confidence level exceeding a threshold, a virtual assistant can be triggered to receive a user command from the audio input. The threshold can be dynamically adjusted in response to perceived events (e.g., events indicating a user may be more or less likely to initiate speech interactions, events indicating a trigger may be difficult to detect, events indicating a trigger was missed, etc.), thereby minimizing both missed triggers and false positive triggering events.Type: GrantFiled: August 24, 2015Date of Patent: September 29, 2020Assignee: Apple Inc.Inventors: Yoon Kim, Thomas R. Gruber, John Bridle

Publication number: 20180218735Abstract: A system and method of speech recognition involving a mobile device. Speech input is received (202) on a mobile device (102) and converted (204) to a set of phonetic symbols. Data relating to the phonetic symbols is transferred (206) from the mobile device over a communications network (104) to a remote processing device (106) where it is used (208) to identity at least one matching data item from a set of data items (114). Data relating to the at least one matching data item is transferred (210) from the remote processing device to the mobile device and presented (214) thereon.Type: ApplicationFiled: March 27, 2018Publication date: August 2, 2018Inventors: Melvyn HUNT, John BRIDLE
