Electronics Projects:Speech Processing Toolkit

Matlab Speech Processing Toolkit with a graphical user interface:

Speech processing is the study of speech signals and the processing methods of these signals. The signals are usually processed in a digital representation, so speech processing can be regarded as a special case of digital signal processing, applied to speech signal. An aspect of speech processing includes the acquisition, manipulation, storage, transfer and output of digital speech signals.

This project can be used to edit speech waveforms (cut, copy or paste selected speech segments) and compute spectrograms. It includes several speech related tools including a filter tool for speech filtering, and a comparison tool for comparing two waveforms using a variety of spectral distance measures. This project can be used to display time-aligned phonetic transcriptions (e.g., TIMIT's .phn files) and for manual segmentation of speech waveforms. It can also perform formant analysis and pitch analysis. In this project, graphical user interface is designed to make this project user friendly.
