Is Deepgram more accurate than WhisperAI?

Deepgram's Nova-2 is a strong in-house model and is highly competitive on its supported languages. WhisperAI runs Whisper large-v3 across 100+ languages. On clean English they're close; on long-tail non-English languages WhisperAI has broader coverage.

Can WhisperAI do real-time streaming like Deepgram?

Deepgram's WebSocket streaming targets sub-300ms latency — the right primitive for live captioning, voice agents, and conversational AI. WhisperAI's primary mode is file-based.

Does WhisperAI offer custom model training like Deepgram?

No. Deepgram's enterprise plans allow training a customer-specific Nova model on your domain audio. WhisperAI uses Whisper large-v3 without per-customer fine-tuning.

Is Deepgram cheaper than WhisperAI?

It depends on volume and shape. Deepgram bills per minute (and per second on streaming); WhisperAI is flat-rate unlimited within fair use.

Does Deepgram have a web app like WhisperAI?

Deepgram is API-first with a developer console for testing — not an end-user app for uploading and managing transcripts.

Which is better for a voice agent or contact-center app?

Deepgram, in most cases. The low-latency streaming, custom model training, keyword boosting, and Voice Agent API are aimed precisely at conversational AI and contact-center deployments.
