Snorri, a software for speech sciences

1 PAROLE - Analysis, perception and recognition of speech

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 WinSnorri 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 and copy synthesis tools allows the user to generate files for the Klatt synthesiser easily. In the context of speech sciences Snorri can therefore be exploited for many purposes, among them, illustrating speech phenomena and investigating acoustic cues of speech sounds and prosody.
