| Outline of Final Research Achievements |
People perceive speech sounds according to a unit called “phoneme.” For example, when native speakers of English hear a set of sounds that continuously changes from the /r/ phoneme to the /l/ phoneme, there is a point where they suddenly hear /l/ instead of /r/. The point is called "categorical boundary," and people tend to be sensitive to the difference between stimuli that stride over this boundary. This type of perception is called “categorical perception.” Study of categorical perception traditionally concerns only perception of small units of sounds such as mono-syllabic words. However, in ordinary conversation settings we normally listen to speech sounds in units that are longer than word, i.e., phrase and sentence. Purpose of the present study is to investigate categorical perception during sentence perception.
