Abstract Correcting speech recognition errors on a mobile touchscreen device is an unavoidable but time-consuming task that re- quires a lot of user effort. To reduce this user effort, we previously proposed an error correction method using long context match with Web N-gram, which we combined with a simple gesture-based user interface. This method automat- ically replaces an error word with its corresponding correct word. However, it was evaluated only substitution errors in sentences, each of which involves only one error. In this pa- per, we extend this method to be used for more general cases when a sentence has more than one error. It recovers not only substitution errors but also deletion errors and insertion er- rors. For recovering deletion errors, it predicts a deleted word based on the phonemes and the part-of-speech tags of its sur- rounding words. Our experimental results show that the pro- posed method recovered the errors more accurately with less user effort than the conventional Word Confusion Network based error correction interface.
