# Enhance Your Voice Agent

> Enhance Dasha BlackBox voice agents with natural conversation features, intelligent call handling, post-call analysis, and powerful integrations.

Make your agents more capable. This section covers natural conversation enhancements, call handling features, post-call analysis, knowledge bases, and integrations.

**What you'll learn:** Ambient noise, fillers, backchannel, noise suppression, call transfers, IVR detection, pre-conversation media, language switching, and more.

***

## Voice & Conversation

### [Ambient Noise](/docs/advanced-features/ambient-noise)

Add realistic background sounds. Eliminates uncanny silence and makes conversations feel natural.

### [Fillers](/docs/advanced-features/fillers)

Insert verbal pauses like "um" and "let me think" during processing delays.

### [Backchannel](/docs/advanced-features/backchannel)

Enable acknowledgment sounds like "mm-hmm" and "I see" while callers speak.

### [Talk First](/docs/advanced-features/talk-first)

Configure your agent to speak first when calls connect. Control opening greetings and timing.

### [Language Switching](/docs/advanced-features/language-switching)

Allow dynamic language switching mid-conversation for multilingual customers.

### [Noise Suppression](/docs/advanced-features/noise-suppression)

Filter background noise from incoming audio using Krisp-powered AI. Improve speech recognition in noisy environments.

***

## Call Handling

### [Call Transfers](/docs/advanced-features/call-transfers)

Transfer calls to human operators:

* **Warm transfer** — Context handoff with agent briefing
* **Cold transfer** — Direct routing without context
* **HTTP transfer** — Webhook-based dynamic routing

### [Max Call Duration](/docs/advanced-features/max-call-duration)

Set automatic time limits for cost control and resource management.

### [Silence Management](/docs/advanced-features/silence-management)

Handle caller silence with configurable reminders and timeouts.

### [IVR Detection](/docs/advanced-features/ivr-detection)

Detect automated systems and voicemail. Leave messages or navigate menus automatically.

### [Pre-Conversation Media](/docs/advanced-features/pre-conversation-media)

Play audio when calls connect — compliance disclosures, branded greetings, or hold music before the agent speaks.

***

## Intelligence & Analysis

### [Post-Call Analysis](/docs/advanced-features/post-call-analysis)

Extract structured data from transcripts — sentiment, outcomes, and custom fields.

### [Knowledge Base](/docs/advanced-features/knowledge-base)

Connect to knowledge bases for accurate information retrieval and reduced hallucinations.

***

## Integration

### [Tools & Functions](/docs/create/tools-and-functions)

Enable agents to perform actions — CRM lookups, appointment scheduling, order status checks.

### [Webhooks](/docs/webhooks-and-events/webhooks-overview)

Receive real-time notifications for call events and enable dynamic configuration.

### [MCP Connections](/docs/create/mcp-connections)

Connect to external MCP servers for standardized tools and data sources.

### [WebSockets](/docs/websockets/websockets-overview)

Real-time bidirectional communication for live monitoring and dynamic control.
