Embodiment 1

[0097] An embodiment of the present invention provides a method for recognizing dialects such as Huizhou dialect based on an HMM model. figure 1 is a flow chart of the HMM model-based dialect recognition method according to an embodiment of the present invention. Such as figure 1 As shown, the steps of the identification method include:

[0098] Step S103, obtaining the acoustic feature sequence of the dialect speech to be recognized using the Viterbi algorithm;

[0099]Step S104, input the acoustic feature sequence into the HMM model library and compare it with the HMM model of the word, and identify the dialect in batches and / or in real time.

[0100] Through the steps of the embodiments of the present invention, it is possible to solve the problem in the related art that it is difficult to identify sub-dialects within the dialect family, and realize accurate and rapid speech recognition of dialects.

[0101] figure 2 It is an optional flow chart of the HMM model-based ...

Abstract

The invention discloses an HMM model-based dialect recognition method, a dialect recognition device, equipment and a medium. The method comprises the following steps: acquiring an acoustic feature sequence of to-be-recognized dialect voices processed by utilizing a Viterbi algorithm; inputting the acoustic feature sequence into an HMM model library, comparing the acoustic feature sequence with anHMM model of words, and identifying dialects in batches and / or in real time. According to the technical scheme of the embodiment of the invention, the voice recognition of dialects such as Huizhou dialects and the like can be realized. The voice recognition rate of dialects is improved.

Description

technical field [0001] The present invention relates to the technical field of speech recognition, in particular to a dialect recognition method, device, equipment and medium based on an HMM model. Background technique [0002] The research on speech recognition has achieved many results, but it still faces many challenges, the biggest challenge is the dialect problem. The incompatibility of dialects in various parts of China makes the accents of people in different regions quite different. This difference has caused great difficulties to the speech recognition system and limited its application and development. [0003] As the carrier of other intangible cultural heritage, dialect itself is also a kind of intangible cultural heritage. As an important tool for people to communicate, dialect carries a large amount of cultural information accumulated by a specific ethnic group in the long-term historical development. irreplaceable role. However, nowadays, the use of dialects...
