Real-time spoken language evaluation system and real-time spoken language evaluation method on mobile equipment

Abstract

A real-time oral English evaluation system and method on a mobile device. The system comprises: a collection module (110) which is used for collecting voice data of a voice to be evaluated; a recognition module (130) which is used for recognizing the voice data collected by the collection module (110) into text data; a matching module (150) which is used for matching the text data obtained by the recognition of the recognition module (130) with text data of a voice sample in a voice sample library so as to obtain a matching result; and an evaluation module (170) which is used for obtaining and outputting a pronunciation score of at least one character or character string in the voice to be evaluated and / or a pronunciation score of the voice to be evaluated according to a predefined evaluation policy and the matching result obtained by the matching of the matching module (150). By way of completing the oral English evaluation system on a mobile device, the dependence of the oral English evaluation system on a network is not only reduced, but the immediate oral English evaluation feedback can also be provided for a user, thereby improving the user experience effect.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a real-time oral English evaluation system and method on a mobile device. Background technique [0002] Most of the existing spoken language evaluation systems use the computer as the client. The user records through the microphone connected to the computer, and the audio data is transmitted to the server through the network, and the evaluation is performed by the algorithm running on the server. The evaluation algorithms are all running on computing resources. (CPU resources, memory resources, storage resources) relatively sufficient server-side computer. [0003] With the popularization of mobile devices, users begin to migrate from computer clients to mobile device clients. Most of the following solutions are used to transplant the client of the evaluation system to the mobile device: the mobile device client collects voice data, transmits the voice data to the server throu...

AI Technical Summary

Problems solved by technology

[0004] Since existing solutions rely on network connections, on the one hand, transmitting voice data over the network consumes data traffic, and on the other hand, mobile devices do not have reliable network connections at all times

Both of the above two points are likely to bring negative user experience to the oral evaluation system. Moreover, building and maintaining the server of the oral evaluation system will also increase additional costs.
