Based on the sources, for your Hindi agent that’s sometimes speaking in a different language, you should verify the `language` parameter in your agent configuration.[(1)](https://docs.retellai.com/api-references/update-agent)[(2)](https://docs.retellai.com/api-references/create-agent)

The `language` parameter specifies what language and dialect the speech recognition operates in.[(1)](https://docs.retellai.com/api-references/update-agent)[(2)](https://docs.retellai.com/api-references/create-agent) For Hindi, you need to set `language` to `"hi-IN"`.[(1)](https://docs.retellai.com/api-references/update-agent)[(2)](https://docs.retellai.com/api-references/create-agent)

When creating or updating your agent, ensure this parameter is correctly set:

```json
{
  "language": "hi-IN"
}

```

[(1)](https://docs.retellai.com/api-references/update-agent)[(2)](https://docs.retellai.com/api-references/create-agent)

If unset, the default value `"en-US"` will apply, which could explain why your agent occasionally speaks English instead of Hindi.[(1)](https://docs.retellai.com/api-references/update-agent)[(2)](https://docs.retellai.com/api-references/create-agent)

To update your existing agent with Agent ID `agent_a2f28109f405f7c21f2696e225`, you can use the Update Voice Agent API endpoint with the correct language parameter.[(1)](https://docs.retellai.com/api-references/update-agent)

Additionally, consider using `boosted_keywords` to bias the transcriber model toward Hindi-specific names, brands, or terms that are commonly used in your conversations.[(1)](https://docs.retellai.com/api-references/update-agent)[(2)](https://docs.retellai.com/api-references/create-agent)
