# Configure Settings

> Overview of all configuration settings for single prompt agents

This page is a quick reference for all settings available in the single prompt agent configuration panel. Each section links to a dedicated page with full details.

## Prompt Settings

These settings appear below the system prompt editor:

| Setting              | Options                     | Default |
| -------------------- | --------------------------- | ------- |
| Enhanced Turn Taking | On / Off                    | Off     |
| Prompt Enhancer      | Disabled / Basic / Advanced | Basic   |

**Enhanced Turn Taking** enables better numeral capturing and backchannel detection for more natural conversations.

**Prompt Enhancer** applies automatic enhancements to your prompt. Basic adds stable model-agnostic improvements; Advanced adds model-aware prompts with live context.

## Voice Settings

Select a voice from Hamsa's library, filtered by language, gender, dialect (Arabic only), and style. Language is set automatically when you choose a voice.

| Setting            | Range                            | Default      |
| ------------------ | -------------------------------- | ------------ |

## LLM Settings

| Setting     | Options                                | Default               |
| ----------- | -------------------------------------- | --------------------- |
| Provider    | OpenAI, Gemini, Groq, DeepMyst, Custom | Gemini                |
| Model       | Varies by provider                     | Gemini 3.1 Flash Lite |
| Temperature | 0.0–1.0                                | 0.2                   |

Temperature controls response variability. Lower values produce more consistent outputs; higher values produce more natural-sounding variation.

<Note>
  GPT-5 family models (GPT-5, GPT-5-Mini, GPT-5-Nano) require temperature = 1.0. This is set automatically when you select a GPT-5 model.
</Note>

## Noise Cancellation

| Send Denoised to STT    | On / Off                                           | Off              |

**Ambient Sound** — Adds subtle ambient sound to the agent's audio. Do not combine with Noise Cancellation.

**Thinking Voice** — Plays a thinking/processing sound between responses.
