The speech API that knows who's talking

Re:WayAI turns real-world conversations into structured, speaker-attributed transcripts. State-of-the-art diarization, LLM speaker attribution and your own private library of enrolled voices — one API call away.

Accuracy
20% fewer errors

Relatively lower diarization error rate than the state-of-the-art open-source model, across four public benchmarks.

Languages
25

European languages in batch, 40 locales in real-time streaming — same pipeline, same speaker accuracy.

Audio retained
0 bytes

Source audio is deleted the moment processing completes. Deleted, not archived.

How it works

From raw audio to named speakers

One job, four stages. Each stage returns its results as soon as it finishes — you never wait for the whole pipeline to read the transcript.

01 / INGEST

Upload or stream

Send any common audio or video format — conversion is handled. Or stream 16 kHz PCM over a WebSocket for real time.

02 / TRANSCRIBE

Accurate ASR

Word-level timestamps in 25 European languages, batch or streaming, built for conversational speech.

03 / DIARIZE

Who spoke when

State-of-the-art segmentation by voice — robust to overlap, crosstalk and far-field microphones.

04 / LLM ATTRIBUTION

Real names

An LLM reads the conversation and names each speaker — with confidence and quoted evidence — or matches voices you've enrolled.

Accuracy

Measured, not promised

Diarization error rate (DER) across four public benchmark corpora — real meetings and in-the-wild media. Identical audio, identical scoring for both systems. Lower is better.

Benchmark State-of-the-art open source Re:WayAI Rel. improvement
Dataset 1 Project meetings, multi-mic rooms 17.05% 13.39% −21.5%
Dataset 2 Natural research meetings, up to ~10 speakers 30.84% 24.10% −21.9%
Dataset 3 In-the-wild media: debates, talk shows, interviews 11.14% 8.61% −22.7%
Dataset 4 Office meetings, single far-field device 27.67% 23.26% −15.9%
Overall Average across all four 21.68% 17.34% −20.0%

DER — diarization error rate, lower is better. Internal evaluation, July 2026, on public diarization benchmarks (descriptions indicate each recording scenario), scored with the same protocol for both systems. Bottom line: 20% relatively fewer diarization errors than the state-of-the-art open-source model on average — and the advantage holds from clean media to far-field meeting rooms.

Capabilities

Built for the hard part: the speakers

Anyone can transcribe. We also get the speakers right.

Overlap-robust diarization

Segmentation that holds up on interruptions, crosstalk and far-field recordings — not just clean studio audio.

LLM speaker attribution

An LLM reads the conversation and puts real names on speakers — each with a confidence score and the quoted evidence behind it.

Advanced LLM capabilities

The LLM stage goes beyond naming: it repairs diarization slips, cleans segment boundaries and turns raw output into a readable transcript.

Real-time streaming

Live transcription over a WebSocket with partial results as words are spoken — straight from a microphone or a call.

Transcript Q&A

Ask questions about any finished transcript — “what did we decide on pricing?” — and the answer is grounded strictly in what was said.

25 European languages

English plus 24 more, through the same pipeline — same diarization, same attribution, same accuracy.

Voice enrollment

Your own database of voices

Enroll a voice once with ~10 seconds of audio. From then on, that person is recognized by name in every recording you send — before the LLM even has to guess.

  • Private by design — your voice library belongs to your account alone; it is never shared or matched against anyone else's audio
  • Messy samples welcome — enrollment audio is diarized first, and the dominant speaker becomes the profile

Privacy & security

Your audio never outlives the job

Voice recordings are some of the most sensitive data there is. The pipeline is built around that fact — GDPR compliant and ISO 27001 certified, not audited into shape afterwards.

Audio deleted immediately

Source audio is deleted the moment processing completes. We never retain, reuse or train on your recordings — there is nothing left to leak.

ISO 27001, our own DC

Re:WayAI is ISO 27001 certified. Every job runs inside our own certified data center — your audio never leaves it, and no third-party cloud or AI API ever touches it.

Transcripts stay yours

Finished transcripts are stored for you until you delete them — retrieve, export or remove them at any time via the console or the API.

On-premise

Audio can't leave the building at all?

The entire pipeline — models included — can be installed on your own hardware and run fully offline, behind your firewall.

Pricing

Transparent pricing, pay as you go

We run our own hardware in our own ISO 27001 data center — no hyperscaler margin baked into every minute. That's exactly why we can undercut the big transcription APIs.

Speaker-attributed transcript with speaker names

The full pipeline in one API call: transcription, speaker diarization and LLM speaker naming — one price, billed per minute of audio.

  • No subscriptions, no minimums — pay only for audio you process
  • Or run any stage on its own: every job is billed per stage
  • Live rates in the console, metered usage API included
