Developed by the International Voice Association, this is a standardized file format for digitized speech. Digital Speech Standard files store information in a high-compression format. You can record an insert or overwrite the sound; the file can also be filled with metadata. This format offers two modes: “Overwrite” and “Enable”. Digital Speech Standard allows for creating voice files suitable for sending via e-mail. This format is powered by IBM ViaVoice software, which enables speech recognition.
