The primary method of interaction between individuals is communication. In the case speech-impaired people, communication them and normal people not understandable by latter as former communicates through gestures sign language. speech-impaired. Today, Internet Things (IoT) can be used for gesture recognition to convert into audible speech. this project, a prototype created such that or languag...

Speech recognition in reverberant environments is a difficult task. Reverberation has the effect of degradation of recognition performance due to acoustic mismatch. We present an optimization method of the wavelet parameters for dereverberation in automatic speech recognition (ASR). By tuning the wavelet parameters to improve the acoustic model likelihood, waveletbased dereverberation methods b...

We present an optimization method of the wavelet parameters for dereverberation in automatic speech recognition (ASR). By tuning the wavelet parameters to improve the acoustic model likelihood, wavelet-based dereverberation methods become more effective in the ASR application. We evaluate several existing wavelet-based methods and optimize them, based on our proposed scheme. Experimental evalua...

This paper presents an approach to the recognition of speech signal using frequency spectral information with Mel frequency for the improvement of speech feature representation in a HMM based recognition approach. A frequency spectral information is incorporated to the conventional Mel spectrum base speech recognition approach. The Mel frequency approach exploits the frequency observation for s...

The cellular phone offers significant benefits but causes several social problems. One such problem is phone use in places where people should not speak, such as trains and libraries. A communication style that would not require voiced speech has the potential to solve this problem. Speech recognition based on electromyography (EMG), which we call "Mime Speech Recognition" is proposed. It not o...

Traditionally the interest in voice gender conversion was of a more theoretical nature rather than founded in real– life applications. However, with the increase in mobile communication and the resulting limitation in transmission bandwidth new approaches to minimising data rates have to be developed. Here voice gender normalisation (VGN) presents an efficient method of achieving higher compres...
