Experimental study on Oriya Retroflex nasal for Speech Synthesis.

Subject  > Humanities Essays  > Linguistics

ABSTRACT: This study intends to examine the allophonic characteristics of the Oriya retroflex nasal phoneme when it occurs in contrastive and complementary distribution in speech. The main thrust is to extract and analyze the spectrographic data of allophonic variants of retroflex nasal and their manifestation, which is significant by considering the acoustic values in different contexts. The variation values are measured in acoustic parameters such as duration of nasal bar, frequency of first, second, third and fourth formant, intensity and fundamental frequency, which are 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 ...

... far as the feature of nasal flap is concerned, the duration of retroflex nasal with rapid transition is comparatively smaller than the non-rapid transition feature ( -flap) of retroflex nasal. 5.In the medial CC context, where the C1 is retroflex and C2 is homo-organic non-nasal retroflex, the behaviour of nasal murmur is continuant (- minus flap) due to its more closing and slow releasing. Conclusion: For the need of speech technology the non instrumental study needs further classification and categorisation of sound units / phoneme in all languages, as it is found in Oriya. The parametric differences of the value may be small and negligible in number. In the generation of continuous speech it may generate unnaturalness. Reference 1Chaudhay, Shreesh.1989.
