Abstract

The embodiment of the present invention provides a pronunciation evaluation method including evaluating a pronunciation to be evaluated according the length, the pitch feature, and the posterior probability of each phoneme in the pronunciation to be evaluated, and the length, the pitch feature, and the posterior probability of each phoneme in a reference pronunciation corresponding to the pronunciation to be evaluated. The pronunciation evaluation method provided by the embodiment of the present invention uses the reference pronunciation as a measurement standard, evaluates the pronunciation to be evaluated from three aspects including the length, the pitch feature, and the posterior probability, can comprehensively reflect the speaking level of a speaker in order that the speaker can understand his / her speaking defects from different angles so as to improve his / her speaking level.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of voice recognition and evaluation, and in particular, to a voice evaluation method. Background technique [0002] The current economic development and cultural exchanges require higher and higher foreign language ability of individuals. How to acquire foreign language skills quickly and efficiently is an urgent problem to be solved in language education. [0003] The increasingly developed computer technology, especially artificial intelligence technology, is an important way to achieve efficient language learning. For example, computer-aided language learning technology can quickly evaluate learners' oral English and point out specific mistakes, so that learners can practice and improve in a targeted manner. [0004] Most of the current speech evaluation technologies are based on the GOP (Goodness Of Pronunciation) algorithm. Given the speech to be evaluated and the corresponding ...
