# Audio Message

> Audio Message sends a voice recording to a customer inside a Keyword Replies flow — a friendlier, more personal alternative to a wall of text. Use this when a customer wants to know where an audio clip can go in a flow, what real-world use cases it fits, or how long/what tone to record it in.

An **Audio Message** plays a voice recording to the customer inside a Keyword Replies flow — see
[Keyword Replies](/learn/whatsapp-keyword-replies#add-flow-components) for how to drag it onto the canvas
alongside the other flow components. Unlike a text message, audio lets a business explain
something in its own voice, which reads as more personal for greetings, walkthroughs, and
instructions.

**Example:** a "Property Introduction Audio" flow sends a welcome text — *"We've prepared a
short audio to help you understand the project highlights before exploring further"* — then
plays a voice recording covering the apartment, amenities, pricing, and lifestyle.

## Where it can go in a flow

An Audio Message can connect after almost any other block, so it fits wherever a spoken
explanation adds value:

| Comes after         | Typical reason to add audio                                    |
| ------------------- | -------------------------------------------------------------- |
| Text Message        | Reinforce a written welcome or instruction in a natural voice  |
| Image Message       | Describe what's in the photo — a property, product, or vehicle |
| Video Message       | Add commentary the video itself doesn't cover                  |
| Document Message    | Explain how to read or use a brochure, invoice, or catalog     |
| Interactive Message | Narrate the options before the customer taps a button          |
| CTA URL Button      | Explain what the link leads to before the customer opens it    |
| User Input Flow     | Guide the customer through what information is being collected |
| AI Reply            | Turn a text answer into a spoken summary for a more human feel |
| Condition           | Explain the branch the conversation just took                  |
| WhatsApp Flow       | Introduce a form before the customer fills it in               |
| HTTP API Response   | Read out live data fetched from an external system             |
| Template Message    | Add a voice follow-up to an approved template send             |

<Tip>
  The real estate **Property Introduction** example above is one instance of this same pattern —
  see [Keyword Replies: Real Estate Property Showcase](/learn/bot-reply-use-case-real-estate) for a full
  worked flow it could extend.
</Tip>

## Best practices

<Warning>
  * Keep audio between **30–60 seconds** whenever possible — long recordings lose customers.
  * Speak clearly, in a friendly tone, with background noise removed.
  * Cover **one topic per audio message** rather than combining several ideas.
  * End with a clear call to action — explore products, contact support, or book a service.
</Warning>

## Frequently asked

<AccordionGroup>
  <Accordion title="What audio formats and file size does Audio Message support?">
    AAC, MP3, AMR, or OGG, up to 16 MB — see the component table in
    [Keyword Replies](/learn/whatsapp-keyword-replies#add-flow-components). An OGG file encoded with the
    Opus codec renders as a native WhatsApp voice note with a waveform; other formats play as a
    regular audio file — see [Audio Messages](/meta-api/messaging/audio-messages).
  </Accordion>

  <Accordion title="Which flow components can an Audio Message follow?">
    Almost any of them — Text, Image, Video, Document, Interactive Message, CTA URL Button, User
    Input Flow, AI Reply, Condition, WhatsApp Flow, HTTP API, and Template Message — see
    [Where it can go in a flow](#where-it-can-go-in-a-flow) above.
  </Accordion>

  <Accordion title="How long should an Audio Message be?">
    30–60 seconds is the sweet spot — long enough to explain one thing clearly, short enough
    that customers actually listen to the end.
  </Accordion>

  <Accordion title="Can Audio Message be the very first message a customer receives?">
    Yes, but the common pattern pairs it with a short lead-in Text or Image message first (e.g.
    `Hi → Welcome Text → Welcome Audio`) so the customer has context before the recording plays.
