When we speak, can vary how use our voices. Our speech be high or low (pitch), loud soft (loudness), and fast slow (duration). This variation in pitch, loudness, duration is called prosody. It a bit like making music. Varying voices when speak express sarcasm emotion even change the meaning of what are saying. So, prosody crucial part spoken language. But do speakers produce prosody? How listen...

The speech enhancement techniques are often employed to improve the quality and intelligibility of the noisy speech signals. This paper discusses a novel technique for speech enhancement which is based on Singular Value Decomposition. This implementation utilizes a Genetic Algorithm based optimization method for reducing the effects of environmental noises from the singular vectors as well as t...

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).

One of the interesting topics on multimedia domain is concerned with empowering computer in order to speech production. Speech synthesis is granting human abilities to the computer for speech production. Data-based approach and process-based approach are the two main approaches on speech synthesis. Each approach has its varied challenges. Unit-selection speech synthesis and statistical parametr...

in this paper, genetic programming is applied for quality improvement of noisy speech signal. therefore, a system including both spectral subtraction and genetic programming is implemented for speech enhancement. in the proposed method, first noise is reduced by spectral subtraction. in the next step, genetic programming trees are trained for more enhancement of noisy signal by mapping the sign...

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 ...
