摘要

应用语音识别技术，研制了一种用于英语发音练习的手持设备。该机器通过显示音高轮廓来帮助纠正语调，并通过计算分割音素的对数后验概率来评估发音准确性。不仅检查音素替换错误，还检查删除和插入错误。由于该算法同时使用了英语和韩语的音位集，因此也可以发现韩语的音位替换错误。这个手持设备使用ARM7 CPU实现，并配备图形LCD。

A handheld English pronunciation evaluation device

A handheld device for practicing English pronunciation is developed by applying speech recognition technology. This machine helps correct the intonation by showing the pitch contour and assesses the pronunciation accuracy by computing the log-posterior probability of the segmented phonemes. Not only the phoneme replacement errors but also deletion and insertion mistakes are checked. It is also possible to find out the Korean phoneme replacement errors because this algorithm employs both English and Korean phoneme sets. This handheld device is implemented using an ARM7 CPU and equips a graphic LCD.
