Resemblyzer
Speaker-verification embeddings from a small generalist encoder.
Drop your audio. Transcript in seconds. First transcript free, then $2 a file or $8 = 1,000 min
Best for speaker similarity scoring + simple clustering-based diarization. Pricing: free.
What it is
A 256-dim speaker encoder reproduction with a clean API. Apache-2.0.
Watch out for: Smaller embeddings vs. WavLM-based SOTA; English-tuned.

Where this category is heading
From the vendor changelogs we track weekly — what changed in August 2026, and what it means if you are choosing now.
AssemblyAI moved summarisation onto an LLM this month; every vendor is racing to return action items, quotes and topics with the text rather than as an add-on.
Whipscribe today Every Whipscribe job already returns an insights payload — summary, key quotes, topics and speakers — from the same job id, at no extra charge.
Deepgram shipped self-hosted container images in August — the market is moving toward audio that stays inside a boundary the customer controls, because teams with customer calls or unreleased material are refusing shared model endpoints.
Whipscribe today Whipscribe runs on our own GPUs in a private, secured cloud. Audio is never forwarded to OpenAI or any third-party model.
The fastest-growing way to use a transcription API is not a form — it is Claude, Cursor or a workflow runner calling it mid-task through MCP.
Whipscribe today Whipscribe ships an MCP server: transcribe, search and summarise from an assistant without wiring anything.
AssemblyAI's 1.0 SDK unified async, realtime and sync; Deepgram's CLI went to 0.3. The unit of work is becoming the folder or the bucket, not the file.
Whipscribe today Submit with an Idempotency-Key and a batch_id, poll by job, retry safely. The S3 connector runs a whole prefix in one grant.
Deepgram added Afrikaans, Georgian and Armenian and improved a dozen more this month. Coverage is widening while quality still clusters around English and the large European languages.
Whipscribe today 99+ languages auto-detected. Ask for a language explicitly when you know it — auto-detect on a short or noisy clip is the most common cause of a wrong-language transcript.
