Use of triphones for demisyllable-based speech synthesis

摘要

The authors describe a novel speech synthesis unit, called a triphone, which is being incorporated into demisyllable-based synthesis systems for Hindi and English. The triphone unit consists of a vowel-consonant-vowel combination and is being used for synthesizing intervocalic consonants of short duration. Results show that the triphone is useful for the synthesis of certain intervocalic consonants which cannot be well modeled using the standard demisyllable approach.
