Phoneme-based Thai speech recognition using fuzzy system and neural network

The Thai speech can be recognized by word or syllable. Most Thai speech recognition systems are word-based and syllable-based system. And most systems use several signal-processing functions in recognition process. These systems have a limit number of word and syllable that they can recognize. This research paper proposed the Thai speech recognition system that recognizes syllable by its phoneme representation using Fuzzy and Neural Network (NN) technique. The proposed system is designed to have desirable properties. 1. The proposed system is no! limited to the number of word or syllable. 2. The proposed system is general enough to be speaker-independent speech recognition system 3. The proposed system has small computation time to be able to be real-time system. 4. The proposed system has acceptable recognition error rate.
