Speech Analyzer is a computer program for recording  and acoustic analysis of speech sounds. You can use it to do the following tasks:

• Perform fundamental frequency, spectrographic and spectral analysis, and duration measurements.
• Add phonemic, orthographic, tone, and gloss transcriptions to phonetic transcriptions in an interlinear format.
• Perform ethnomusicological analysis of music recordings.
• Use slowed playback, repeat loops and overlays to assist with perception and mimicry of sounds for language learning.

It can record and open WAV files and it can open MP3 files. The transcription data is stored in human readable XML format. The data can be read and analyzed by the Phonology Assistant program which can help to analyze the phonemics of the phonetic data. Speech Analyzer data can also be imported into a FLEx database to provide audio examples in a lexicon. All transcription data can be entered in Unicode.
