SPPAS is a free audio annotation tool that allows you to create, visualize and search annotations for audio data. This software is issued under the terms of the GNU Public License. It is able to produce automatically speech segmentation annotations from a recorded speech sound and its transcription. Some special features are also offered for managing corpora of annotated files.

SPPAS's data files are XML-based. However SPPAS is compatible with Praat, Elan, Transcriber, and many others. SPPAS is written in Python and runs on Windows, Macintosh and Unix platforms.

By using SPPAS, you agree to cite one reference in your publications. See the references page for information on how to cite SPPAS, and for published related work.
