Free software for speech analysis
Using tools for investigating speech signals is an invaluable help to teach phonetics and more generally speech sciences. For several years we have undertaken the development of the software WinSnoori which is for both speech scientists as a research tool and teachers in phonetics as an illustration tool. It consists of five types of tools:
to edit speech signals,
to annotate phonetically or orthographically speech signals. WinSnorri offers tools to explore annotated corpora automatically,
to analyse speech with several spectral analyses and monitor spectral peaks along time,
to study prosody. Besides pitch calculation it is possible to synthesise new signals by modifying the F0 curve and/or the speech rate,
to generate parameters for the Klatt synthesiser. A user friendly graphic interface together with copy synthesis tools (automatic formant tracking, automatic amplitude adjustment) allows the user to generate files for the Klatt synthesiser easily.
In the context of speech sciences WinSnoori can therefore be exploited for many purposes, among them, illustrating speech phenomena and investigating acoustic cues of speech sounds and prosody.
If you are interested in getting the source code of WinSnoori do not hesitate to contact me. Interface has been developed in Borland C++ with OWL library which is not available any more. However, it seems that there exists a modern open version of OWL name OWLNext. If somebody wants to try I can give access to the WinSnoori sources.
In parallel we also developed a Java version of WinSnoori called JSnoori which is more focused on language learning. This version contains new tools and the possibility of writing and using scripts in Jython.

Snorri was originally developed on a Masscomp machine in 1987 . It then was adapted to X11 with the Motif toolkit for Unix machines before being ported on Windows. Snorri is the name of the Unix version and WinSnoori that of the Windows (95, NT, 98, 2000, XP, Seven) version. The Windows version works fine with Wine on Linux machines.
