# How to use text to speech for custom call flow messages
> Create natural sounding greetings and announcements using text to speech in Quo.
Text to speech helps you turn written messages into audio, so you can update greetings quickly without recording a new message every time.
Quo’s enhanced text to speech uses a more natural sounding voice. If you have existing text to speech greetings, you may need to edit and save them again to apply the updated voice.
***
## **Enhanced text to speech**
Enhanced text to speech is designed to sound warm and professional so callers hear a greeting that feels human rather than robotic.
Standard text to speech voices are still supported and remain available in the dropdown under **Text to speech**.
***
## **Where text to speech is available**
Text to speech is available in several places within Quo’s call flow builder.
**All plans**
* [Voicemail greetings](https://support.quo.com/core-concepts/administration/call-flows/voicemail#create-your-greeting)
**Business and Scale plans**
* [Phone menu greetings](https://support.quo.com/core-concepts/administration/call-flows/phone-menu#create-your-greeting)
* [Play audio messages](https://support.quo.com/core-concepts/administration/call-flows/play-audio)
***
## **How to set up text to speech**
1. Navigate to the call flow builder
2. Select **an option with a greeting**
* This could be **Voicemail**, **Phone menu** or **Play audio**
3. Choose **Text to speech**
4. Choose from the available voice options:
* **4 natural voices** — newer, high-quality options
* **1 legacy text-to-speech voice** — the original TTS option
5. Click **Generate** to create your greeting
6. Preview your greeting using the **Play button**
7. Once satisfied, click **Save** to save your changes
When switching between **Standard voice** and **Natural voice**, the **Generate** button needs to be clicked to generate a new preview.
6. Save when you’re ready
Text to speech is a good fit for announcements that change often, like holiday hours or temporary notices. If you expect to switch routing back after a short period, [temporary call flows](https://support.quo.com/core-concepts/administration/call-flows/temp-call-flows) can help you manage those changes more efficiently.
## **Write a greeting that sounds natural**
### **Make numbers easy to understand**
Enhanced text to speech interprets numbers based on context. Writing numbers out and adding pauses can help avoid unexpected pronunciation.
**Phone numbers**
| ✅ Do | ❌ Don't |
| ------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------ |
| Write numbers phonetically with pauses, such as “two zero one... five five five... one two three four”. | Enter formatted numbers like “201-555-1234”. These may be read inconsistently. |
**Emergency numbers**
| ✅ Do | ❌ Don't |
| :------------------------------------- | :------------------------------------------------------- |
| Write “nine one one” instead of “911”. | Write “911”, which may be read as “nine hundred eleven”. |
**Menu options**
| ✅ Do | ❌ Don't |
| :------------------------------------------------------------------- | :------------------------------------------------------------------- |
| Keep options simple, such as “Press one for sales, two for support”. | Rely on typing numbers out if you need it pronounced a specific way. |
### **Control pacing with punctuation**
Enhanced text to speech doesn’t support speech markup, but punctuation can still shape delivery.
* Use ellipses **(...)** for longer pauses
* Use commas **(,)** for brief pauses
* Use periods **(.)** for full stops
> **Example**\
> *Thank you for calling... We’ll be right with you. Press one for sales, or stay on the line.*
### **Handle names, acronyms, and special terms**
If a word is mispronounced, try spelling it the way it sounds. For acronyms, spacing out letters often helps.
**Company names and acronyms**
| ✅ Do | ❌ Don't |
| :------------------------------------------------------------------ | :----------------------------------------------------------------------------------------- |
| Write names phonetically if needed, such as “Kwo” instead of “Quo”. | Skip previewing your greeting to determine if you need to try spelling a word differently. |
| Space out letters for acronyms, such as “I T” instead of “IT”. | Keep letters together, as it may be read as a word. |
**Addresses and codes**
| ✅ Do | ❌ Don't |
| :------------------------------------------------------------------------ | :----------------------------------------------------------------- |
| Write write numbers as words, such as “Suite three hundred”. | Rely on numbers formatted as "1234" for building numbers or codes. |
| Spell out directions, such as “North Main Street” instead of “N Main St”. | Use shortened addressed like, “N Main St”. |
## **Troubleshooting**
Edit the message and save it again to apply the enhanced voice.
Try spelling the word phonetically or adjusting punctuation to guide pacing.
