Isolated English Word Recognition System: Appropriate for Bengali-accented English

Accents of English have been investigated for many years both from the perspective of native and non-native speakers of the language. Various research results imply that non-native speakers of English language produce certain speech characteristics which are uncommon in native speakers speech. This is because non-native speakers do not produce the same tongue movement as native speakers. This paper presents an isolated English word recognition system devised with the speech of local Bangladeshi people, who are also non-native speakers of English language. Here, we have also noticed a different speech characteristic which is not available within the speech of native English speakers. Two acoustic features, pitch and formants have been utilized to develop the system. The system is speaker-independent and stands on Template based approach. The recognition method applied here is very simple and the recognition accuracy is also very satisfactory.
