Using Technology for Pronunciation: a Brief History
Early years: "repeat after me" Goals - accent reduction, native-like pronunciation Technology was used for listening or for providing a native-speaker amodel ASR provided limited feedback - technology is/was limited to awords/phones
Past 20+ years: "talk to me" Pedagogical emphasis on intelligibility Used for interaction with software or other speakers Connected speech, suprasegmentals and internet-enabled xcommunication

FluSpeak (A part of Automatic Speech Recognition (ASR) Software)
English pronunciation, intonation, dialog practice with pronunciation testing
Research Question: Is FLuSpeak software reliable in terms of teaching pronunciation?
Pilot study participants: 36 Korean EFL college students
Method: Students recorded voices, ASR analysis was compared to NS instructor scores
Analysis: WinSPASS program run on the four kinds of pronunciation ratings. Correlations between FluSpeak scores and NEI scores weak to zero at the intonation level.

2 Some consistent pronunciation errors and foreign [non native-like] accents and intonation patterns, but
the speaker's pronunciation of the sentence is intelligible only with some effort.
3 Occasional nonnative pronunciation errors, but the speaker's pronunciation of the sentence is clearly
intelligible with effort from the listener.
