- Waveform audio file created in the NIST SPHERE format, which is often used in speech recognition research; often contains a recording of a person speaking; can be provided as input to speech recognition systems.
- A lossy file format used to compress speech in Global Standard for Mobile (GSM) telecommunications. It is very effective for reducing audio file size. However, encoding and decoding audio signals severally is discouraged as the final product will have a lot of noise. Popular with some voice mail software but it is CPU intensive.
