Abstract
The traditional English pronunciation recognition system fails to timely feed back and correct learners' mispro-nunciation,which misleads learners and leads to learners' slow improvement in English level. Therefore,a new error speech au-tomatic recognition system for English pronunciation is designed. The system is composed of voice recording module,voice play-ing module,English pronunciation scoring module,and pronunciation formant image display module. The pronunciation scoring process of the scoring module is given to realize the effective scoring of English pronunciation and storage of scores. The pronun-ciation formant graphic display module is adopted to clearly express the differences between learners' pronunciations and stan-dard pronunciations,so as to correct their wrong pronunciations. The detection performance of wrong pronunciations is improved by using the independent threshold mode and the English phoneme error detection procedure. Different phonemes are measured with the independent threshold to make the wrong speech automatic recognition results of English pronunciation more scientific and accurate. The experimental results show that the designed system has a high error speech automatic recognition capability.关键词
