Phoneme-based Recognition of Finnish Words with Dynamic Dictionaries


In this paper we present an isolated -word recognition system using first HMM to recognize the underlying sequence of phonemes, then DP and phoneme n -gram matching techniques to determi ne the corresponding nearest idealized phoneme sequences in the dictionary. Our approach is based on the observation that there is almost a one -to-one match between phonemes and letters in the official written Finnish language and a representation of the words in the dictionary as phoneme sequences. A significant advantage of our system lies in its ability to easily modify the dictionary without retraining the ASR models. Speaker dependent word recognition experiments can show an achievement of 95% recognition rates.
