This paper presents a new incremental speaker adaptation technique for isolated Mandarin syllables using four sets of phonetically balanced sentences. This algorithm was based on a newly developed Segmental Probability Model(SPM) which was found specially suitable for isolated Mandarin syllable recognition. Each Mandarin syllable is conventionally divided into INITIAL and FINAL parts and based on the INITIAL/FINAL structure of Mandarin syllables, a segment sharing concept is first proposed. A computer algorithm was then developed to select automatically four sets of phonetically balanced sentences with different selection criterion from a large Chinese text corpus. After the four-stage adaptation procedure, the recognition rate for a new speaker can be improved from 63.05% to 92.96%.
