5 Feb 2010	Gautam Vallabha	Features of the Toolbox (take from the website): * Dual time-waveform and spectrogram displays * Records speech directly into MATLAB NEW * Displays time-aligned phonetic transcriptions (e.g., TIMIT's .phn files) * Manual segmentation of speech waveforms * Waveform editing - cutting, copying or pasting speech segments * Formant analysis - displays formant tracks of F1, F2 and F3 * Pitch analysis * Filter tool - filters speech signal at cutoff frequencies specified by the user * Comparison tool - compares two waveforms using several spectral distance measures * Speech degradation - adds noise to the speech signal at an SNR specified by the user
