Embodiment Construction

[0029] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, systems, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0030] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate. Please refer to figure 1 , figure 1 The implementation process of a speech recognition method provided by the embodiment of the present invention is shown, and the details are as follows:

[0031] In step S101, input the target audio data into the pre-constructed acous...

Abstract

The invention is applicable to the technical field of terminal equipment. The invention provides a speech recognition method, a speech recognition device and terminal equipment. The method comprises the following steps: inputting target speech data into a pre-constructed acoustic model based on a neural network to obtain a target pinyin sequence; inputting the target pinyin sequence into a pre-constructed language model based on a neural network to obtain a target text sequence. A speech recognition process is split into two parts; wherein one part is a sequence from audio data to pinyin; onepart is from a pinyin sequence to a character sequence, so that the dependence on data volume is greatly reduced, the recognition accuracy from the pinyin sequence to the character sequence is greatlyimproved due to facts that there are only more than 1400 pinyin with tones and more than 7000 common Chinese characters, and the application requirement of commercial-level voice recognition accuracyis met.

Description

technical field [0001] The invention belongs to the technical field of terminal equipment, and in particular relates to a speech recognition method, device and terminal equipment. Background technique [0002] Traditional speech recognition technologies represented by Gaussian Mixed Model (GMM), Hidden Markov Model (HMM), Mel Cepstral Coefficient (MFCC), n-gram language model, etc., although the accuracy has been greatly improved , but still cannot meet the application requirements of commercial grade. [0003] In recent years, under the influence of deep learning technology, automatic speech recognition technology has made some breakthroughs. However, compared with traditional speech recognition systems, the overall framework has not changed much, and the user experience is still poor. With the rapid development of mobile devices, speech recognition technology, as the basic application of mobile devices, needs to be further improved in terms of accuracy, speed, and ease of...
