TrueSpeech was developed by DSP Group as a speech-compression format for applications such as voice recording and telephony. A DSP Group TrueSpeech file contains compressed speech audio that uses the TrueSpeech codec.
The format was used by multimedia and communications software that included TrueSpeech support. MIME types historically associated with it include application/dsptype and audio/tsplayer.
TrueSpeech is a legacy format. Support was more common in older Windows multimedia software and is not included in many current audio players.
On Windows, open the file with Awave Studio or another audio application that specifically supports DSP Group TrueSpeech. Modern default media players may not recognise this format.
If no compatible application is available on the current platform, use a TrueSpeech-capable converter to decode the file and save it in a more widely supported audio format.
Awave Studio can be used to open supported TrueSpeech files and export the decoded audio to a common format such as WAV. Conversion requires software with a TrueSpeech decoder; simply changing the file extension does not convert the audio.
