Deepgram is a developer-focused speech AI platform that offers speech-to-text, text-to-speech, and unified voice-agent APIs for building conversational applications, transcription pipelines, and audio intelligence workflows. Its speech-to-text models (branded Nova and Flux) target different needs — Nova for high-accuracy, multilingual transcription at scale, and Flux for low-latency, turn-aware conversational recognition suitable for live voice agents. Deepgram also provides Aura (TTS) for natural, domain-tuned voices and a Voice Agent API that integrates STT, TTS, and optional LLM orchestration in a single WebSocket-based interface.

Key features include real-time streaming and batch transcription, speaker diarization, automatic punctuation and smart formatting, keyword/keyterm boosting, filler-word detection, multi-channel audio support, automatic language detection, transcript redaction, and the ability to train or deploy custom and industry-tuned models. The platform emphasizes ultra-low latency (sub-300ms turn detection for conversational agents), scalability (cloud, VPC, or on-prem/self-hosted options), and enterprise security and compliance (SOC2, HIPAA, GDPR capabilities). Deepgram provides SDKs, developer documentation, and tools like a Playground to experiment with models and pipelines.

Typical use cases span contact centers and voice agents, meeting and media transcription (podcasts, broadcasts, captions), speech analytics and conversational intelligence (intent, sentiment, topic detection), content search and indexing, accessibility (captions and summaries), and bespoke industry deployments (healthcare, legal, finance) that benefit from domain-specific vocabularies and custom models. The primary audience includes developers, product teams, platform integrators, enterprises requiring secure and scalable voice infrastructure, and data teams seeking to extract structured insights from audio.

From a commercial perspective, Deepgram is positioned as an API-driven, enterprise-capable vendor that balances out-of-the-box accuracy with customization and deployment flexibility. It also offers options for pre-paid enterprise plans and self-hosted/on-premises engines for organizations with strict compliance or latency requirements.
