Experimental study on Oriya Retroflex nasal for Speech Synthesis.

ABSTRACT: This study intends to examine the allophonic characteristics of the Oriya retroflexed pinched phoneme when it occurs in contrastive and complementary diffusion in speech. The main(prenominal) hug is to extract and analyze the spectrographic data of allophonic variants of retroflex impecunious and their manifestation, which is significant by considering the acoustic determine in divers(prenominal) backgrounds. The variation values argon c atomic number 18ful in acoustic parameters such as duration of nasal bar, frequence of first, second, third and fourth formant, intensity and fundamental frequency, which argon perceptually unique. This is necessary for the development of speech database. The variations of the speech units are classified into (1) co-articulatory variations, which to some extent may be negligible, and (2) allophonic variations, which are contextually significant. A Phoneme, which is an abstract unit comprising a contract of features, is realis e by the actual pronunciation of the phones/ allophones by the aborigine speakers. The Speech synthesis system has to map the allophonic variations and their contextual rules in respect of each phoneme so as to interpret it into phonetic conversion module. The Oriya retroflex nasal phoneme and its different manifestations expound by the Descriptivists in their non-instrumental study, therefore, need further classification, potpourri and revision on the basis of acoustic features.

Introduction: The front studies show the allophonic variations of Oriya phonemes on the basis of their complementary distribution in devise as well as in syllable initial, medial and last(a) position. Comp lementary features of phonemes are positiona! l specific, which have been realized by the changing of its degree of place and manner features. In Oriya, the secure change of manner feature is noticed in the case of retroflex nasal when it precedes and follows the back category of vowels. In that context the retroflex nasal becomes retroflex nasal flap. A convocation of Oriya retroflex allophonic... If you want to get a honest essay, hostelry it on our website: OrderEssay.net
