A powerful voice-AI platform unlocking real-time, highly accurate speech-to-text, text-to-speech, and conversational voice agents for developers and enterprises.
Deepgram is a foundational voice AI platform designed to transform human–machine interaction. It equips developers and enterprises with advanced speech-to-text (STT), text-to-speech (TTS), and voice agent APIs, all underpinned by state-of-the-art deep learning models. Trusted by over 200,000 developers, Deepgram delivers faster, more accurate results, and cost-efficient services—accessible via cloud APIs or self-/single-tenant deployments.
Built around custom deep learning infrastructure, Deepgram handles everything from transcription and synthesis to conversation orchestration, directly competing on speed, accuracy, and scalability.
Deepgram leverages proprietary deep learning models with advanced Transformer architectures, such as Nova-2/Nova-3, and delivers exceptional transcription accuracy, significantly lower latency (<300 ms), and much faster processing compared to legacy systems. It also offers domain adaptation and customization for enhanced performance.
Yes, new users receive $200 in free credits. This generous onboarding bundle allows users to explore speech-to-text, text-to-speech, and voice agent capabilities without needing a credit card.
Deepgram processes audio at remarkable speeds—up to 40× faster than traditional systems—and can transcribe an hour of audio in about 12 seconds, enabling real-time and high-throughput workloads.
Deepgram supports 36+ languages and dialects, offering strong multilingual transcription suitable for global applications.
Yes, Deepgram offers real-time transcription via streaming APIs and WebSocket interfaces, ideal for live use cases like call centres and interactive voice applications.
Absolutely. Deepgram supports enterprise-grade deployments with robust security, comprehensive compliance options (e.g., HIPAA/GDPR), and flexible hosting—including cloud-managed, single-tenant (Deepgram Dedicated), or self-hosted configurations—to meet strict regulatory and performance requirements.
Beyond transcription, Deepgram includes powerful audio intelligence tools such as summarization, sentiment analysis, topic detection, redaction, diarization, and smart formatting—enabling deeper insights from voice data.
Deepgram supports temporary token-based authentication via short-lived JWTs (Time To Live of 30 seconds by default). These are ideal for secure, client-side access, especially in real-time or browser-based applications. They reduce risk exposure and ensure smoother interaction without persistent API keys.
Yes, Deepgram offers a managed Whisper Cloud API that enables users to leverage Whisper model sizes (tiny to large) while benefiting from Deepgram’s added features like diarization and metadata, in a fully hosted setup. Note: live streaming isn't supported via Whisper; the Nova model is recommended instead for streaming use.
Deepgram offers comprehensive developer support, including documentation, API references, SDKs (Python, JavaScript, Go, and . . .NET), an interactive API playground, starter apps, and an active developer community on Discord and forums for peer and official support.
