# Build a Hindi assistant

> Configure an assistant that speaks natural Hindi, understands Hinglish, and follows callers who switch language.

In this tutorial you'll build an outbound assistant that follows up on loan applications in Hindi.

**1. Start from a template**

Go to **AI Assistants** and click **NBFC Loan Follow-up**. Set the **Agent name**, for example `Neha`, and replace the lender details in the instructions with your own.

**2. Set the language**

On the **Voice** tab:

* **Primary language**: Hindi
* **Auto switch language**: on, so the assistant follows callers who reply in English

**3. Choose a Hindi voice**

Select **Sarvam** (model **Bulbul v3**) and preview the voices. Pick one that sounds natural for your audience and keep the speed close to 1.0x.

**4. Translate the instructions**

On the **Prompt** tab, click **Translate prompt**. Orato rewrites the instructions in Devanagari with a natural, spoken tone. Placeholders like `{customer_name}` and your section structure stay as they are.

Review the result, then update the **First message** in Hindi, for example:

```text theme={null}
नमस्ते {{customer_name}} जी, मैं नेहा बोल रही हूँ। आपके लोन आवेदन के बारे में दो मिनट बात कर सकते हैं?
```

**5. Check the transcriber**

On the **Advanced** tab, Orato picks a transcriber from your languages. To set it yourself, click **Change** and choose **Sarvam AI → Saaras v4 Realtime**.

**6. Pick the AI model**

On the **Settings** tab, set **Role** to **Outbound** and choose a caller ID. Try **Anthropic Claude Haiku 4.5** first, then compare with **Sarvam AI → Sarvam 105B**.

**7. Test with native speakers**

Use **Talk** and ask colleagues who speak Hindi to try it. Listen for unnatural phrasing, wrong number formats, and how it handles Hinglish.

## Tips

* Ask the assistant to say amounts the way callers expect, for example in lakhs.
* Keep compliance language (fees, interest, consent) in **Guardrails**, and review the translated version carefully.
* See [Multilingual assistants](/multilingual) for other Indian languages.
