# Dasha AI

> Dasha AI is a platform for building ultra-realistic voice and text AI agents that handle real-time conversations with human-like fluency.

## Product

Dasha enables developers to create conversational AI agents for telephony (PSTN/SIP), WebRTC, and text channels. Agents use Dasha's proprietary speech synthesis for ultra-realistic voice quality with sub-second latency. The platform is REST-API-first — if you can make an API call, you can ship a voice agent — with full low-level programmatic control of conversation flows available when you need it.

Key capabilities:
- Ultra-realistic AI voice agents with natural turn-taking and interruption handling
- Telephony integration (inbound and outbound calls via PSTN and SIP), BYOC — bring your own carrier and phone numbers
- WebRTC support for browser-based voice interactions
- REST API for programmatic control and CRM/helpdesk integration, with full low-level conversation flow control beyond it
- Use any LLM (GPT, Claude, Gemini, etc.) and switch LLMs mid-conversation
- Real-time transcription, call recordings, and post-call analysis
- 30+ languages with mid-call language switching
- Voice cloning and custom voice creation (unlimited voice clones)
- Agent-to-agent orchestration for complex multi-step workflows
- Sub-second response latency for natural conversations
- 10,000+ concurrent calls in production
- 99.99% uptime SLA

## Competitive Differentiators

### vs. API Platforms (Twilio, Vonage, Amazon Connect)
Dasha provides a complete voice AI solution rather than requiring developers to assemble multiple APIs (STT, TTS, telephony, NLU). This reduces development time from months to days and ensures optimized end-to-end latency. Unlike API platforms, Dasha handles conversation state management, turn-taking, and interruption detection natively.

### vs. Open Source Frameworks (Rasa, Vocode, LiveKit)
While open-source tools offer flexibility, they require significant infrastructure expertise to deploy at production scale. Dasha handles infrastructure, scaling, speech processing, and telephony, letting developers focus on conversation design rather than DevOps.

### vs. DIY Solutions
Building a custom voice AI stack requires expertise across speech recognition, synthesis, telephony, NLU, and real-time systems. Dasha provides all capabilities in a single platform with sub-second latency, eliminating the need to integrate and tune multiple components.
