COLEA is a Matlab Speech Processing Toolkit with a graphical user interface.

This program can be used to edit speech waveforms (cut, copy or paste selected speech segments) and compute spectrogramss. 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.COLEA 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. A manual describing COLEA is included. For more information about this program visit the web site:
