Development of Phoneme Dominated Database for Limited Domain T-T-S in Hindi

摘要

Maximum digital information is available to fewer people who can read or understand a particularlanguage. The corpus is the basis for developing speech synthesis and recognition systems. In India, almostall speech research and development affiliations are developing their own speech corpora for Hindilanguage, which is the first language for more than 200 million people. The primary goal of this paper is toreview the speech corpus created by various institutes and organizations so that the scientists and languagetechnologists can recognize the crucial role of corpus development in the field of building ASR and TTSsystems. This aim is to bring together all the information related to the recording, volume and quality ofspeech data in speech corpus to facilitate the work of researchers in the field of speech recognition andsynthesis. This paper describes development of medium size database for Metro rail passenger informationsystems using HMM based technique in our organization for above application. Phoneme is chosen asbasic speech unit of the database. The result shows that a medium size database consisting of 630utterances with 12,614 words, 11572 tokens of phonemes covering 38 phonemes are generated in ourdatabase and it cover maximum possible phonetic context.
