oronasal region, as an important organ of taste and smell, being respected for its impact on the resonace, which is crucial for any normal speech production. different congenital, acquired and/or developmentalpdefect, may not only have impacts on the quality of respiration, phonation, resonance, also on the process of a normal speech. this article will enable readers to have more focus in such ...

This study was carried out to improve the quality of acted emotional speech. In the recent paradigm shift in speech collection techniques, methods for the collection of high-quality and spontaneous speech has been strongly focused on. However, such methods involve various constraints: such as the difficulty in controlling utterances and sound quality. Hence, our study daringly focuses on acted ...

Problem statement: In speech communication, speech coding aims at preserving the speech quality with lower coding bitrate. When considering the communication environment, various types of noises deteriorates the speech quality. The expressive speech with different speaking styles may cause different speech quality with the same coding method. Approach: This research proposed a study of speech c...

storaging or transmission of speech signals at very low bit rate is a hot area in the field of speech processing. we used stochastic inter-frame interpolators and vector quantization (vq) as a new method for developing a high quality 1200 bps speech vocoder. the objective and subjecgtive test results show that performance of the new vocoder is compairable with 4800 bps standard vocoders (as celp).
