Abstract

The invention discloses a method for detecting English statement pronunciation quality suitable for a mobile device. The method comprises the following steps that statements sent by a user are collected; collected voice signals are preprocessed; voice characteristic parameters of the preprocessed voice signals are extracted so that the voice characteristic parameters of the collected voice signals can be obtained; according to the voice characteristic parameters, the collected voice signals are compared with standard voice signals, so that scoring is conducted on the content, the emotion, the speed, the stress, the rhythm and the intonation; according to at least one of a content score, an emotion score, a speed score, a stress score, a rhythm score and an intonation score, a final score of the collected voice signals is obtained; according to the final score, whether the collected voice signals are correct in pronunciation or not is judged. According to the method for detecting English statement pronunciation quality suitable for the mobile device, the accuracy of statement pronunciation detection can be improved and the problem that a voice pronunciation detecting system can only be used by the user on a PC terminal is solved.

Description

technical field [0001] The invention relates to the technical field of speech signal processing, in particular to a method for detecting the pronunciation quality of English sentences adapted to mobile devices. Background technique [0002] The application of signal processing technology in language learning is an important part of the integration of information technology and language learning. Its goal is to combine the latest speech technology with current teaching and learning methods to establish a computer-assisted language learning system. [0003] The earliest method of objective speech evaluation can be traced back to the late 1940s, the articulation index AI (Articulationhidex) method proposed by N.R.French and J.C.Steinberg in 1947. T.P.Barnwell and S.R.Quackenbus made a systematic summary of the research work on the objective evaluation of speech quality before the mid-1980s, and published a book on the objective evaluation of speech quality in 1988.
