Embodiment Construction

[0028] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0029] The present invention is a computer-assisted Chinese learning method and device. The computer-assisted Chinese learning method is divided into two stages: preliminary preparation and pronunciation teaching:

[0030] The first stage is based on the preparatory work of the language ecological survey. It plays a decisive role in the teaching of Chinese learners whose native language is not Chinese. It includes voice data collection, voice data analysis and feature extraction, and acquires local people to learn Chinese pronunciation. Time expert knowledge and typical bias characteristics. Select part of the local Chinese Mandarin speech database speech and standard speech database speech as the scoring speech database data, and finally use the feature vector in the scoring speech database to establish a score mapping between the f...

Abstract

The invention relates to a voice data mapping method and apparatus. The voice data mapping method comprises: acquiring voice pronunciation data and establishing a local native language voice database, a local Chinese voice database, and a standard Chinese voice database; establishing a scoring voice database; performing analysis and statistic on the scoring voice database in order to acquire typical biased errors of local Chinese pronunciation; analyzing voice data in the local native language voice database, the local Chinese voice database, and the scoring voice database in order to obtain expert knowledge data and establishing an expert knowledge database; selecting a characteristic vector according to the expert knowledge data in the expert knowledge database and extracting voice parameters from the expert knowledge data, wherein the characteristic vector comprises characteristic parameters and the weight of the characteristic parameters; and establishing a scoring mapping relation between the characteristic vector and scoring data. The voice data mapping method and apparatus is capable of establishing an accurate scoring mapping relation between the characteristic vectors and scoring data based on language ecology.

Description

Technical field [0001] The present invention relates to a method and device for mapping voice data, in particular to a method and device for mapping voice data based on language ecology. Background technique [0002] In recent years, with the advancement of speech technology such as speech recognition, computer-assisted language learning technology has gradually attracted the attention of academia and education as a new interdisciplinary research topic. [0003] Existing methods of using computers for Putonghua proficiency testing and instructional learning adopt a scoring mechanism for Putonghua proficiency test in units of segments, and use speech recognition methods to calculate the scores of candidates taking the Putonghua proficiency test and point out the candidates’ pronunciation errors. [0004] However, the prior art has the following defects: [0005] This technology is mainly aimed at the application of Putonghua proficiency test in my country. The candidate’s mother tongue...
