Phoneme-based Recognition of Finnish Words with Dynamic Dictionaries
نویسندگان
چکیده
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.

Allophone-based acoustic modeling for Persian phoneme recognition
Phoneme recognition is one of the fundamental phases of automatic speech recognition. Coarticulation which refers to the integration of sounds, is one of the important obstacles in phoneme recognition. In other words, each phone is influenced and changed by the characteristics of its neighbor phones, and coarticulation is responsible for most of these changes. The idea of modeling the effects o...

This paper presents the design and performance of a Malay grapheme to phoneme (G2P) tool for generating the pronunciation dictionary for a Malay automatic speech recognition system (ASR). The G2P tool is a rule based system. It is flexible in adding and removing rules, and handling of English words. The G2P tool also contains morphological and syllable tool, which it uses to determine the pronu...
متن کاملCombined Optimisation of Baseforms and Model Parameters in Speech Recognition Based on Acoustic Subword Units
A major challenge in speech recognition is creating a lexicon which is robust to inter-and intra-speaker variations. This is even more so in speech recognisers based on non-linguistic units, e.g., acoustic subword units (ASWUs), since no standard pronunciation dictionaries are available. Thus the baseforms describing the vocabulary words in terms of the recognition units need to be generated fr...
