# Select the Model and voice

* **Models & Voice section** decide karta hai ki aapka voice agent conversations mein **kaise sunega, sochega aur bolega**.
* Sabse pehle **Pipeline Mode** choose karein:
  * **STT + LLM + TTS pipeline** aapko zyada control deta hai kyunki speech-to-text, AI brain aur text-to-speech alag-alag configure hote hain.
  * **Realtime model** ek single unified setup deta hai jo faster configuration ke liye useful hai.
* **TTS (Text-to-Speech)** decide karta hai agent ki voice kaisi hogi — aisa voice model select karein jo aapke brand aur audience se match kare.
* **LLM (Large Language Model)** agent ka brain hota hai — yeh response quality, speed aur instruction follow karne ki ability control karta hai. Model choose karte waqt speed, cost aur complexity ka dhyan rakhein.
* **STT (Speech-to-Text)** user ki voice ko text mein convert karta hai — better understanding ke liye high-accuracy model aur correct language select karein.
* **Noise Cancellation** enable karein taaki background noise remove ho aur calls noisy environment mein bhi clear rahein.
* Pipeline mode, models, voice aur noise settings ko sahi configure karne se aapka voice agent **natural, intelligent aur professional** sound karega.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://helpdocumentation.gitbook.io/user-documentation/voice-ai/voice-ai-overview-in-hindi/select-the-model-and-voice.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
