Empathic Voice Interface — voice AI that reads and responds to emotion in speech.
Best for wellness, coaching, and companion apps where tone matters as much as words. Pricing: see vendor pricing.
What it is
Hume's Empathic Voice Interface (EVI) is a streaming voice API that returns transcription plus emotional prosody scores and generates speech tuned to user affect. Developers integrate EVI over WebSocket with their own logic or use Hume's hosted conversational LLM. EVI competes with OpenAI Realtime by emphasizing emotional context over pure latency.
Watch out for: Emotion claims should be validated for your population; English-led model coverage.

How is Whipscribe different from Hume EVI?
Hume EVI is another vendor's product; Whipscribe is a per-minute transcription service. Recordings are transcribed on our own servers and never used for training, and every job returns five formats plus an AI summary, quotes and topics. The first 20 minutes of any recording are transcribed free, and a pack from $6 (500 minutes) transcribes the rest and opens every export.
What does transcription cost if I use Whipscribe instead of Hume EVI?
$0.012 a minute — about $0.72 an audio hour — bought as credits that never expire. There is no subscription and no monthly minimum: a 3-hour recording is about $2.16, a thousand-hour archive is about $720 once. The first 20 minutes of any recording are transcribed free, and a pack from $6 (500 minutes) transcribes the rest and opens every export, so you can see what your recording holds before paying anything.
Where is the Hume EVI category heading?
Three things are moving across the whole speech-to-text market right now: summaries, action items and speaker insights generated on top of the transcript rather than sold separately; private, secured deployment where the audio never leaves a boundary you control; and agent access — transcription exposed as a tool that Claude, Cursor or a workflow runner can call directly. Whipscribe ships all three today: per-job insights, our own servers, and an MCP server.
Whipscribe is a hosted transcription service. If you want transcripts without running infrastructure, paste a URL or drop a file in the form below — you'll have a transcript in seconds.
