Welcome to the world of Scilab Speech

Speech Synthesize

1．pitch_marks = find_pmarks(wavefile, fs_in)

　　----calculates and returns the pitch marks (placed at peaks in the short-time energy function) for the input speech signal.

2．plot_pmarks(wavefile, pm)

　　----draw some lines in the place where the pitch frequency is.

3．[vuv]=detect_vuv(wavefile, fs, pm)

　　----return voiced/unvoiced decisions considering pitch marks.

4 ．y = tdpsola(wavefile, fs, pscale, tscale, pm, vuv)

　　----adjust the prosodics.
