# Deepgram Voice AI Platform

> Deepgram is a foundational Voice AI platform for developers, offering unified APIs for Speech-to-Text (STT), Text-to-Speech (TTS), and autonomous Voice Agent orchestration. Available as a managed API (US, EU, and Australia endpoints), in-VPC, or self-hosted.

## Products
- [Voice Agent API](https://deepgram.com/product/voice-agent-api): A single WebSocket API unifying STT, LLM orchestration, and TTS with sub-300ms transcription latency. Flat-rate pricing from $4.50/hr, BYO LLM and BYO TTS options, function calling, barge-in, and mid-session reconfiguration ([docs](https://developers.deepgram.com/docs/voice-agent)).
- [Speech-to-Text (STT)](https://deepgram.com/product/speech-to-text):
    - **Flux**: Conversational speech recognition purpose-built for voice agents, with built-in end-of-turn detection, natural interruption handling, and word-level timestamps. Available in English (`flux-general-en`) and Multilingual (`flux-general-multi`, 10 languages with in-conversation language switching) ([docs](https://developers.deepgram.com/docs/flux/quickstart)).
    - **Nova-3**: Flagship transcription model for batch and streaming, with 50+ languages, keyterm prompting, diarization, smart formatting, and noise robustness ([docs](https://developers.deepgram.com/docs/stt/getting-started)).
    - **Industry-tuned & custom models**: Domain models including Nova-3 Medical, plus custom models trained on customer data.
- [Text-to-Speech (TTS)](https://deepgram.com/product/text-to-speech):
    - **Flux TTS**: Streaming-first, conversation-native TTS on `/v2/speak` (WebSocket and batch REST). Generally available and the default Voice Agent voice (`flux-kit-en`). Barge-in reporting of exactly what the user heard, mid-session speed control, and 36 English voices across seven accents ([docs](https://developers.deepgram.com/docs/flux-tts/overview)).
- [Audio Intelligence](https://deepgram.com/product/audio-intelligence): Summarization, sentiment analysis, topic detection, and intent recognition ([docs](https://developers.deepgram.com/docs/audio-intelligence)).
