Cross-language speech recognition method and device

Abstract

The invention discloses cross-language speech recognition method and device, and relates to the technical field of speech processing. A concrete implementation mode of the method comprises the steps of acquiring cross-language sample data, training the sample data as input data of a preset neural network model, and obtaining a language category discriminator; inputting audio to be recognized intothe language category discriminator, and segmenting the audio to be recognized according to a language category determined by the language category discriminator; and utilizing a recognition engine corresponding to the determined language category for recognizing the segmented audio to be recognized. According to the implementation mode, an existing speed recognition engine has no need to be modified, so that the cost is low, the recognition rate is high, and the accuracy is high.

Description

technical field

[0001] The invention relates to the field of speech processing, in particular to a cross-language speech recognition method and device. Background technique

[0002] The intelligence and integration of electronic equipment are getting higher and higher, and the traditional information retrieval and menu operation methods are increasingly unable to meet the requirements. There is an urgent need for a more convenient information retrieval and command operation method to replace the traditional button operation. Speech recognition technology came into being. However, in most traditional automatic speech recognition systems, only the most commonly used language of the country is supported, and other languages ​​are less supported or not supported. For this situation, the conventional approach is: (1) Different languages ​​are considered independently, and a language model is trained from scratch for each language. (2) In the acoustic model, the most commonly us...
