Abstract
The present invention provides a mandarin voice evaluating system and a mandarin voice evaluating method. The system comprises a storage unit for storing acoustic templates, wherein each acoustic template comprises standard pronunciation; an input unit for inputting voice; a comparison unit used for comparing the pronunciation phonemes and standard phonemes; an obtaining unit for obtaining a phoneme similarity; a judging unit for judging the type of a tone according to the phoneme similarity; an output unit for outputting the tone; and an evaluating unit for evaluating the accuracy of the voice.
Description
Technical field
The present invention relates to a kind of pronunciation and judge system and method, especially a kind of mandarin pronunciation evaluation system and method.
Background technology
Due to the lifting of computer computation ability in recent years and the progress of speech recognition technology, the application of speech processes in daily life grows with each passing day, as speech recognition, phonetic synthesis and language person identification etc., wherein, in transnational language learning, carry out the research of non-mother tongue study with area of computer aided user and considerably paid attention to, all input researchs one after another of each side.
Wherein, take Chinese as maximum languages of number of users, therefore learning Chinese forms the main flow trend of language learning gradually again.But in the process of language learning, qualified teachers' shortage and expensive study are propped up and are sold many people and step back for it, although released on the market many language pronouncing study products, wherein, is no lack of the language repeater that has technical development comparatively ripe, but it only can provide with reading, user's speech analysis information can not be provided, the product that pronounces to mark even if having some based on speech signal analysis, but be to differentiate by comparison of wave shape, its reliability of differentiating result is not high, or cannot provide the tone of high-accuracy to distinguish for Chinese speech pronunciation.Therefore, development is a kind of based on unspecified person speech recognition technology, and being used to provide user self pronunciation is the technology that industrial community is desired most ardently development with respect to the method for discrimination of type under Received Pronunciation content similarity and tone.
Summary of the invention
The present invention solves the above-mentioned technical matters existing in background technology, and proposes mandarin pronunciation evaluation system and method.
Technical solution of the present invention is:
The present invention is a kind of mandarin pronunciation evaluation system, and this system comprises storage unit, deposits acoustics template, and each acoustics template comprises standard pronunciation; Input block, input voice; Comparing unit, comparison pronunciation phonemes and standard phoneme; Acquiring unit, obtains phoneme similarity; Judging unit, judges tone type according to phoneme similarity; Output unit, output tone; Pass judgment on unit, pass judgment on voice correctness.
A kind of mandarin pronunciation evaluation method, its special character is: the method includes the steps of:
1) deposit acoustics template, each acoustics template comprises standard pronunciation;
2) input voice;
3) according to time section comparison pronunciation phonemes and standard phoneme;
4) obtain phoneme similarity;
5) judge tone type according to phoneme similarity;
6) output tone;
7) pass judgment on voice correctness.
Above-mentioned steps 2) after, comprise
2.1) store user's pronunciation;
2.2) calculate the time section of each pronunciation phonemes.
Above-mentioned steps 5), be to judge tone type according to time section.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of mandarin pronunciation evaluation system of the present invention;
