Abstract

A spoken language evaluation method and device, comprising: obtaining a speech material to be evaluated and obtaining an evaluation dimension from a plurality of evaluation dimensions, and extracting evaluation features of the speech material to be evaluated according to the evaluation dimension; Score, get the spoken language evaluation value, and score the evaluation features according to the pre-stored oral language norm model, and get the public average level value for the speech material to be evaluated; output the evaluation result of the speech material to be evaluated according to the spoken language evaluation value and the public average level value . The spoken language evaluation method and device provided by the present invention use the seven dimensions of pronunciation and intonation ability, vocabulary use ability, grammar use ability, language logic ability, as well as the degree of theme concentration, the degree of expressiveness in a single sentence and the degree of completeness of expression to evaluate the learners' actual oral ability. Comprehensive evaluation and precise guidance provide comprehensive, practical and effective help for learners to improve their oral expression ability in various real situations.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a spoken language evaluation method and device. Background technique [0002] With the continuous development of economic globalization, people are gradually paying attention to the learning of spoken foreign languages. At present, there are many electronic products (such as point readers, learning computers) and oral evaluation applications on mobile terminals that assist oral evaluation in the market. In practice, it is found that whether it is an electronic product or an oral evaluation application, it is impossible to accurately evaluate the actual oral ability of the learners by simply providing listening and speaking practice materials and roughly scoring the actual oral ability of the follow-up. Help learners improve their speaking skills. Contents of the invention [0003] In view of the above problems, the present invention provides a speaking evaluation me...
