SIL International has just announced the release of version 3.0 of Speech Analyzer (SA), a tool for recording, transcribing and analyzing speech sounds:
Linguists will find SA useful to perform duration measurements and fundamental frequency, spectrographic and spectral analyses. SA can also combine phonetic, phonemic, orthographic, tone and gloss transcriptions in an interlinear format. Features to enhance language learning include slowed playback, repeat loops and overlays to assist with perception and mimicry of sounds. With SA, ethnomusicologists can perform analysis of music recordings. Version 3.0 is the first significant release of SA since version 2.7 (June 2005).
New features include:
- Unicode support and support for Transcription Encoding Converters for data from previous versions
- Import data in MP3 and WMA formats
- Import and export MusicXML
Other Features:
