Abstract
In this article, we report users’ perceptions of query input errors and query reformulation strategies in voice search using data collected through a laboratory user study. Our results reveal that: 1) users’ perceived obstacles during a voice search can be related to speech recognition errors and topic complexity; 2) users naturally develop different strategies to deal with various types of words (e.g., acronyms, single-worded queries, non-English words) with high error rates in speech recognition; and 3) users can have various emotional reactions when encounter voice input errors and they develop preferred usage occasions for voice search.
