Tamil Phonemes Recognition for Normal and Hearing Impaired: A Survey Janakiraman.S Pondicherry University, Puducherry, INDIA Pavithra.S Research Scholar, Sathiyabama University Chennai, Tamil Nadu, INDIA __________________________________________________________________________________________ Abstract: This paper presents a survey on speech recognition models and Tamil Phonemes Recognition Model. Speech is human’s most efficient mode of communication. Beyond efficiency, humans are comfortable and familiar with speech. Research work on Tamil speech recognition, although lagging than other languages, is becoming more intensive than before and several researches have been published in the last few years. In spoken language, a phoneme is a basic, theoretical unit of sound that can change the meaning of a word. Depending on the language and the sounds used, a phoneme may be written consistently with one letter; however, there are many exceptions to this rule. The range of the possible applications is wide and includes: voice-controlled appliances, fully featured speech-to-text software, automation of operator-assisted services, and voice recognition aids for the handicapped. In this paper it is proposed to develop a Speech Recognition System for both Normal Hearing and Hearing Impaired children with Visual Feedback for Tamil phonemes. The proposed Phoneme Recognition System use Radial Basis Function Networks and visual feedback is a Graphical User Interface to provide the correct (or) incorrect articulation of phoneme visually. ______________________________________________________________________________________
