how to play pre-recorded audio
I want to play precorded audio file when a user call the agent. How can I do this? Can I upload a mp3 somehow and then play it?
THere’s the easiest way to play a pre-recorded audio file (-mp3, ‑wav, etc.) when someone calls your Voiceflow agent over the Twilio/Vonage Phone integration.

Feel free to add multiple Custom Action steps if you want to string together several audio clips, or combine them with regular Speak steps for TTS prompts.
- Host the audio file• Upload the file to any HTTPS-accessible location (AWS S3, Cloudfront, GitHub Pages, your own server, etc.). • Copy the direct URL (for example: `https://my-files.s3.amazonaws.com/welcome.mp3`). Voiceflow itself doesn’t store audio assets today.
- Add a **Custom Action → TwiML** step in your flow (You’ll find it in the Logic section of the canvas.)
- Paste TwiML that tells Twilio to play the file:```xml<?xml version="1.0" encoding="UTF-8"?><Response><Play>https://my-files.s3.amazonaws.com/welcome.mp3</Play></Response>```That’s it—when the call reaches this step Twilio streams the mp3 to the caller before the conversation continues. If you need to collect DTMF afterwards you can wrap the `<Play>` in a `<Gather>`.
<audio> tag. Using a Custom Action with raw TwiML is the supported way to play media files.Docs for reference
