# Agents: Advanced (https://docs.envocal.ai/agents/advanced/)

> Fine-tune how the Agent listens, understands, and responds during conversations. These options help improve accuracy, responsiveness, and overall interaction quality.

## Automatic Turn Detection
Controls **how the Agent knows when a user has finished speaking** and when it should respond.

### Semantic
The Agent listens for **meaning and intent**, not just silence.
It continuously tries to understand if the user has finished speaking, even if the user pauses.
**Example:**
> “I was wondering if you could help me book a demo… maybe tomorrow?”
👉 The agent waits for the full thought before responding.

Note that you can even control **how eager** is the Agent to respond.

### Standard (Timeout-Based)
The Agent responds after a **pause or silence** based on a fixed timeout (e.g., 1–2 seconds of no speech)

### When to Use Each
- **Semantic** → More natural, human-like conversations (recommended)  
- **Standard** → Simpler use cases or when timing must be strictly controlled  

## Noise Reduction
Improves how well the Agent hears the user by filtering background noise.

### Near-Field
Designed for users speaking **close to the microphone** as phone calls, headset, laptop mic.
👉 Best for most use cases

### Far-Field
Designed for users speaking **from a distance** as speakerphones, meeting rooms, kiosks.
👉 Helps capture speech in noisier environments

### When to Use Each
- **Near-field** → One-on-one calls (default)  
- **Far-field** → Shared spaces or noisy environments

## Transcription
There settings control how the Agent converts speech into text.

### Automatic Language Detection
The Agent automatically detects the spoken language out of **50+ supported**.
This is best when the users are expected to speak different languages, however it comes with a drawback in accuracy, especially with shorted sentences.

### Preselected Language
You define a specific language (e.g., English) which improves accuracy even for shorter sentences. 

Note that you can even choose from **high precision** or **high accuracy**

### Additional Instructions
You can provide extra guidance to improve transcription accuracy.
### Examples
> - “Expect email addresses and phone numbers”  
> - “Support technical terms and abbreviations”  

### Why This Matters
Better transcription leads to more accurate understanding, better tool usage and more natural responses.
