https://serverfault.com/questions/543825/converting-celp-audio-files
Update the question so it's on-topic for Server Fault. Closed 2 years ago. I've been tasked with converting CELP audio files (usually stored as .wav files) into a more mainstream format. CELP is a audio format specialized for speech and used in many voice recorders.

MP3 is a coding format for digital audio developed largely by the Fraunhofer Society in Germany, with support from other digital scientists in the US and elsewhere. Originally defined as the third audio format of the MPEG-1 standard, it was retained and further extended — defining additional bit-rates and support for more audio channels — as the third audio format …
audio - Philips CELP file - Stack Overflow
https://stackoverflow.com/questions/31281999/philips-celp-file
I got file recorded in Philips speechexec. I've tried to edit header of this file to open it with different codec but I didn't succeeded. I used Philips CELP codec but I couldn't read it either. I got information about that this file could be encrypted in SpeechExec transcription software but this application only work with Philips kit.

Here's a note about LPC and CELP audio codings by Van Jacobson <[email protected]>: Several people used the words "LPC" and "CELP" interchangeably. They are very different. An LPC (Linear Predictive Coding) coder fits speech to a simple, analytic model of the vocal tract, then throws away the speech & ships the parameters of the best-fit model.
Speex Audio Codec, Version 1.2
https://www.loc.gov/preservation/digital/formats/fdd/fdd000259.shtml
Speex Audio Codec, Version 1.2. Description. Speech codec designed for packet networks and voice over IP (VoIP) applications but not for mobile phones. File-based compression is also supported. The flexible codec is based on Code Excited Linear Prediction (CELP) and supports a wide range of speech quality and bit-rates.
Code-excited linear prediction - Wikipedia
https://en.wikipedia.org/wiki/Code-excited_linear_prediction
Code-excited linear prediction (CELP) is a linear predictive speech coding algorithm originally proposed by Manfred R. Schroeder and Bishnu S. Atal in 1985. At the time, it provided significantly better quality than existing low bit-rate algorithms, such as residual-excited linear prediction (RELP) and linear predictive coding (LPC) vocoders (e.g., FS-1015).
Opus (audio format) - Wikipedia
https://en.wikipedia.org/wiki/Opus_(audio_format)
The Opus format is based on a combination of the full-bandwidth CELT format and the speech-oriented SILK format, both heavily modified: CELT is based on the modified discrete cosine transform (MDCT) that most music codecs use, using CELP techniques in the frequency domain for better prediction, while SILK uses linear predictive coding (LPC) and an optional Long-Term …
