Play Audio lets your Agent play a recording instead of speaking synthesized text. It works well for stable announcements, disclosures, hold messages, or other audio that must remain consistent. ## Configure Play Audio Add Play Audio in the Functions section of the Agent editor. Choose the approved audio source and tell the Agent exactly when it should play and what should happen afterward. Keep a spoken fallback in the instructions in case the audio cannot be played. ## Test the complete call Place a staged call and confirm: * the correct audio starts at the intended moment * its volume and quality are clear over a phone connection * the Agent waits for it to finish * the conversation continues correctly afterward Play Audio is separate from background audio, which creates ambient or foreground sound across more of the call.
