An HMM-based method for Thai spelling speech recognition
Spelling speech recognition can be applied for several purposes including enhancement of speech recognition systems and implementation of name retrieval systems. This paper presents an approach to construct three recognizers for the three commonlyused Thai spelling methods based on hidden Markov models (HMMs). The Thai phonetic characteristics, alphabet system and spelling methods are analyzed....
متن کاملThai spelling analysis for automatic spelling speech recognition
Spelling speech recognition can be applied for several purposes including enhancement of speech recognition systems and implementation of name retrieval systems. This paper presents a Thai spelling analysis to develop a Thai spelling speech recognizer. The Thai phonetic characteristics, alphabet system and spelling methods have been analyzed. As a training resource, two alternative corpora, a s...
متن کاملHmm Based Speech Recognition of Continuous Thai Digits
Progress on speech recognition of Thai digit strings is presented in this paper. HTK 3.0 was chosen to implement the HMM-based speech recognizer. MFCCs and their delta and delta-delta terms were used as speech features. Several set of HMM parameters were investigated. Two kinds of word searching methods were tried. Recognition accuracy of 98.7% on test data was achieved with a fixed length word...
متن کاملThai Spelling Recognition Using a Continuous Speech Corpus
Spelling recognition is an approach to enhance a speech recognizer’s ability to cope with incorrectly recognized words and out-of-vocabulary words. This paper presents a general framework for Thai speech recognition enhanced with spelling recognition. In order to implement Thai spelling recognition, Thai alphabets and their spelling methods are analyzed. Based on hidden Markov models, we propos...
متن کاملUsing Tone Information in Thai Spelling Speech Recognition
Spelling recognition is a workaround to recognize unfamiliar words, such as proper names or unregistered words in a dictionary, which typically cause ambiguous pronunciations. In the Thai spelling task, some alphabets cannot be differentiated by only spectral cues. In such cases, tonal cues play a critical role in distinguishing those alphabets. In this paper, we therefore introduce Thai spelli...
