The Voconix API for professionals

Generating personalized voice messages

The Voconix API allows you to create custom audio messages by combining:

  • AI voices in multiple languages, with customizable pauses and transitions.
  • Hold or background music , chosen from a paginated library (genres, types, free search).
  • Precise mixing : adjusting volume, timing (start/end of music, pauses between vocal blocks), for a professional result.

Example of use : Send a personalized welcome message for a telephone switchboard, a voice campaign, or customer service, with music adapted to your brand image.
