Patent number: 11893988Abstract: The disclosure provides a speech control method, a speech control apparatus, an electronic device, and a storage medium. The method includes: acquiring target audio data sent by a client, the target audio data including audio data collected by the client within a target duration before wake-up and audio data collected by the client after wake-up; performing speech recognition on the target audio data; and controlling the client based on an instruction recognized from a second audio segment of the target audio data in response to recognizing a wake-up word from a first audio segment at beginning of the target audio data; in which, the second audio segment is later than the first audio segment or has an overlapping portion with the first audio segment.Type: GrantFiled: June 24, 2021Date of Patent: February 6, 2024Assignee: BEIJING BAIDU NETCOM SCIENCE AND TECHNOLOGY CO., LTD.Inventors: Song Yang, Saisai Zou, Jieyi Cao, Junyao Shao

Publication number: 20220310064Abstract: A method for training a speech recognition model, a device and a storage medium, which relate to the field of computer technologies, and particularly to the fields of speech recognition technologies, deep learning technologies, or the like, are disclosed. The method for training a speech recognition model includes: obtaining a fusion probability of each of at least one candidate text corresponding to a speech based on an acoustic decoding model and a language model; selecting a preset number of one or more candidate texts based on the fusion probability of each of the at least one candidate text, and determining a predicted text based on the preset number of one or more candidate texts; and obtaining a loss function based on the predicted text and a standard text corresponding to the speech, and training the speech recognition model based on the loss function.Type: ApplicationFiled: January 10, 2022Publication date: September 29, 2022Applicant: BEIJING BAIDU NETCOM SCIENCE TECHNOLOGY CO., LTD.Inventors: Junyao SHAO, Xiaoyin FU, Qiguang ZANG, Zhijie CHEN, Mingxin LIANG, Huanxin ZHENG, Sheng QIAN

Patent number: 11393458Abstract: Embodiments of the present disclosure relate to a method and apparatus for speech recognition. The method includes: determining, based on an acoustic score of a speech frame in a speech signal, a non-silence frame in the speech signal; determining a buffer frame between adjacent non-silence frames based on the acoustic score of the speech frame, a modeling unit corresponding to the buffer frame characterizing a beginning or end of a sentence; and decoding a speech frame after removing the buffer frame from the speech signal, to obtain a speech recognition result.Type: GrantFiled: December 3, 2019Date of Patent: July 19, 2022Assignee: BEIJING BAIDU NETCOM SCIENCE AND TECHNOLOGY CO., LTD.Inventors: Junyao Shao, Sheng Qian

Patent number: 11355113Abstract: A method, apparatus, device, and computer readable storage medium for recognizing and decoding a voice based on a streaming attention model are provided. The method may include generating a plurality of acoustic paths for decoding the voice using the streaming attention model, and then merging acoustic paths with identical last syllables of the plurality of acoustic paths to obtain a plurality of merged acoustic paths. The method may further include selecting a preset number of acoustic paths from the plurality of merged acoustic paths as retained candidate acoustic paths. Embodiments of the present disclosure present a concept that acoustic score calculating of a current voice fragment is only affected by its last voice fragment and has nothing to do with earlier voice history, and merge acoustic paths with the identical last syllables of the plurality of candidate acoustic paths.Type: GrantFiled: March 9, 2020Date of Patent: June 7, 2022Assignee: Baidu Online Network Technology (Beijing) Co., Ltd.Inventors: Junyao Shao, Sheng Qian, Lei Jia

Publication number: 20220068265Abstract: The disclosure discloses a method for displaying a streaming speech recognition result, relates to a field of speech technologies, deep learning technologies and natural language processing technologies. The method includes: obtaining a plurality of continuous speech segments of an input audio stream, and simulating an end of a target speech segment in the plurality of continuous speech segments as a sentence ending, performing feature extraction on a current speech segment to be recognized based on a first feature extraction mode when the current speech segment is the target speech segment; performing feature extraction on the current speech segment based on a second feature extraction mode when the current speech segment is not the target speech segment; and obtaining a real-time recognition result by inputting a feature sequence extracted from the current speech segment into a streaming multi-layer truncated attention model, and displaying the real-time recognition result.Type: ApplicationFiled: November 8, 2021Publication date: March 3, 2022Inventors: Junyao SHAO, Sheng QIAN
