Embodiment Construction

[0012] Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0013] Such as figure 1 As shown, the speech recognition model training method according to one embodiment can be performed as follows. Firstly, in step S1002, the terminal may obtain the user's speech sample by collecting the speech of the user reading the sample aloud. According to an embodiment, the sample for the user to read aloud may be a static sample, such as a list of Chinese pinyin, an English alphabet, a list of numbers, a list of confusing words, and the like. According to another embodiment, the samples for the user to read aloud may also be dynamic samples, for example, containing speech content that is misrecognized by the user, such as confusingly pronounced syllables, wrong pronunciations, and the like. Then in step S1004, the server performs feature extraction on the collected user voice samples, and then in step S1006, a voice reco...

Abstract

The application discloses a speech recognition model training method, a speech recognition model training device and a terminal. According to the application, the speech recognition model training method can comprise the steps of acquiring speech of a reading sample of a user to obtain a user speech sample, extracting features of the acquired user speech sample and creating a speech recognition model according to the extracted features. By the adoption of the method and the device of the application, a speech recognition model base can be updated according to user features, thereby improving the success rate of speech recognition and improving the user experience.

Description

technical field [0001] The present application relates to a speech recognition model training method and device and a speech recognition terminal. Background technique [0002] In existing speech recognition methods, speech recognition can be performed according to an existing acoustic model, for example, one method is to perform speech recognition using a speech dictionary. The scheme provides a method for forming a phonetic dictionary, including sorting out words that are often used together in daily life, and storing the standard pronunciation of the words through syllable codes. At the same time, the scheme discloses that the voice code in the voice dictionary is compared with the code formed by the input voice to realize voice recognition. [0003] Since the above method cannot perform speech recognition for a specific user's usage habits, especially when the user has his own pronunciation characteristics, the recognition rate may drop significantly. Contents of the ...
