Generate high-quality speech audio from text using the Telnyx TTS API.

Usage

To convert text to speech, run the script:

The script outputs the path to the generated audio file on success.

    • Telnyx.NaturalHD.luna

{baseDir}/​scripts/​telnyx-tts.py "Hello! This is a test of Telnyx text to speech." -o /​tmp/​tts-output.mp3

Then return the audio file:
