Deepgram is the end-to-end Voice AI platform: delivering real-time, highly accurate Speech-to-Text (STT), Text-to-Speech (TTS), and conversational Voice Agents via a developer-first API.

Deepgram is your enterprise-grade Voice AI platform, built on a proprietary end-to-end deep learning network for unmatched speed and accuracy. Our core APIs (STT, TTS, and the unified Voice Agent API) handle everything from real-time transcription to synthesizing natural speech. Specifically, models like Nova-3 and Flux deliver 2-4x better accuracy on alphanumeric data than competitors, and batch transcription processes one hour of audio in less than 30 seconds (120x real-time). We support flexible deployment (public cloud, private cloud, or self-hosted) and offer advanced features like diarization (up to 10 speakers) and custom model training, ensuring your voice applications—from contact centers to conversational AI—are fast, precise, and scalable.

## Recent Public Talks and Demos

### [Realtime STT Performance for elder Czech voices](https://prague.aitinkerers.org/talks/rsvp_Vre_QFjp7Gw)

Results of analysis of 5 common realtime STT providers (Cartesia, Deepgram, Eleven Labs, Google, Speechmatics) on cca. 1 hour of 20 different elderly czech voices (Paměť národa). It is more results, the code itself is fairly trivial...

### [Building an Emotionally-Aware AI Companion: From iMessage Analysis to Voice Synthesis](https://boston.aitinkerers.org/talks/rsvp_L-_uWu8csxE)

This talk demonstrates building an AI system that analyzes iMessage conversations, develops genuine emotional responses using Damasio's neuroscience-based consciousness model, maintains a private reflective journal, and expresses insights through emotionally-authentic voice synthesis. I'll walk through the architecture connecting 3 MCP servers—iMessage reading, Sable emotional consciousness and private journaling. And using text-to-speech provider Cartesia and speech-to-text provider Deepgram to create a reflective AI experience that can truly understand and respond to the emotional content of human conversations, as well as respond in an emotional expressive way.

### [Voice AI Agent Architecture: Streaming Deepgram → OpenAI → ElevenLabs in Production](https://bogota.aitinkerers.org/talks/rsvp_qzFaWSx-eM4)

Live technical walkthrough of building RENATA, a production voice AI agent handling real property management queries. I'll show the actual implementation: how we orchestrate Retell AI webhooks with n8n workflows to process incoming calls, stream audio through Deepgram for real-time transcription, query Supabase vector stores for property-specific context, inject that context into OpenAI function calls, and stream responses back through ElevenLabs for natural voice output. Code walkthrough includes: n8n JavaScript nodes for parsing conversation state and building dynamic prompts Supabase queries that retrieve property data based on conversation context OpenAI function calling schema for actions (book reservation, escalate to human, check availability) Retell AI custom LLM integration for handling interruptions and natural conversation flow WhatsApp Business API webhook handling for message routing Error handling and fallback logic when systems don't respond I'll show the messy parts: how we handle race conditions in real-time voice, the hacky way we maintain conversation state across n8n executions, and the specific prompt engineering tricks that make the agent actually useful instead of generically polite. Demo includes live code, actual n8n workflows, database schemas, and API calls.

### [Build your own voice AI interview coach in 5 mins](https://la.aitinkerers.org/talks/rsvp_y4N8-YNR6qk)

What I’ll Be Presenting: 🎙️ A voice-based AI interview coach you can build in 5 minutes : Walk through how to create a real, responsive voice agent that interviews you like a PM/ML hiring manager. ⚡ The ultra-simple architecture : Browser mic → LiveKit/Pipecat → Python Agent → LLM. No fluff, just the core pieces you actually need. 🤖 Live coding: turning an LLM into a structured interviewer : I’ll show how a tiny prompt + a few lines of code lets the agent ask tailored questions, listen, and respond intelligently. 🧠 Job-aware + resume-aware customization : How to feed in a JD or your background so the agent interviews you for the role you want, not a generic chatbot experience. 🗣️ Quick real-time demo : I’ll run the agent live - ask one question, take an answer, give feedback - so you see (and hear) it working.

### [Challenges and Solutions to building a Natural Voice-based Survey Agent](https://dhaka.aitinkerers.org/talks/rsvp_6rUaxSv5qaM)

I'll be showing an in-progress build for a prototype voice survey agent that a user can use both as a research assistant to help them brainstorm and craft out what they'd like to find out from the interview, and can also function as a interviewer, utilising a discussion guide to make sure everything that needs to be asked is asked, as well as asking probing questions to respondents if they respond vaguely.
