# Speech Settings - Pronunciation 🗣️
Teach your agent how to pronounce specific names, brands, and terms. Add a word as it's written and tell the agent how to say it out loud, so tricky names always sound right on a call.
Each pronunciation rule has two fields:
* **Word as written** — the term exactly as it appears in your prompt or data (for example, `ChatGPT`).
* **How to say it** — a simple, spelled-out version of how it should sound (for example, `Chat gee-pee-tee`).
When the agent is about to say the written word during a call, it uses your spelled-out version instead.
***
**Adding a rule**
Click **Add Word** to create a new row, then fill in both fields. Use the **play** button (▶) to hear how the spelled-out version sounds in your agent's current voice, and the **✕** button to remove a rule you no longer need.
{% hint style="info" %}
Write the **How to say it** field the way it should *sound*, not the way it's spelled — break the word into syllables and use hyphens or spaces to guide the agent (for example, `Dapta` → `Dap-tah`). The written word can be up to 50 characters and the spoken version up to 100.
{% endhint %}
{% hint style="warning" %}
**Every occurrence of the written word is replaced, including inside longer words.** A rule matches the text wherever it appears, not just when it stands alone. For example, a rule for `am/pm` would also affect words that contain those letters, so `example` or `program` could be mispronounced. Prefer full, distinctive words as your **Word as written** to avoid replacing text you didn't intend.
{% endhint %}
***
**When to use it**
Pronunciation rules are ideal for:
* Brand and product names (`ChatGPT`, `Cal.com`)
* Company or people's names with non-obvious pronunciation
* Acronyms that should be spelled out letter by letter
* Industry-specific or foreign terms
> **💡 Tip:** For pronunciation tweaks that are specific to phone numbers, emails, or codes inside a single prompt, you can also spell them out directly in your instructions — see [Improving pronunciation](/ai-voice-agents/how-to-set-up-your-ai-voice-agent/improving-pronunciation.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.dapta.ai/ai-voice-agents/how-to-set-up-your-ai-voice-agent/voice-agent-settings-guide/speech-settings-pronunciation.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
