SFS/WASP Version 1.54
Windows Tool for Speech Analysis
WASP is a free program for the recording, display and analysis of speech. With WASP you can record and replay speech signals, save them and reload them from disk, edit annotations, and display spectrograms and a fundamental frequency track.
WASP is a simple application that is complete in itself but which is also designed to be compatible with the Speech Filing System (SFS) tools for speech research.
