Performance of adapting non-native speech in isolated speech recognizer

This paper presents the pronunciation performance between native and non-native speakers of Malay sounds in isolated speech recognizer (ISR). Speaker adaptation methods are combined to solve the performance decrease that recognizers are faced with native and non-native speech of speaker-independent...
