Independent benchmark

Independently benchmarked against Microsoft, Google and Whisper

Researchers at the University of Bucharest scored seven transcription systems on over 126 hours of Romanian speech. Vatis finished top two of the seven overall — first on Antena 1 news and first on podcasts, and more accurate than Google on every single set.

  • ~95%

    Accurate on Antena 1 news

    95.6% on the Antena 1 news set — the highest of all seven systems tested, ahead of Microsoft, Google and every Whisper model.

  • ~90%

    Accurate on podcasts

    89.8% on podcasts — first again on unscripted conversation, and more than 12 points clearer than Google on the same audio.

  • 6 of 6

    Domains ahead of Google

    Vatis transcribed more accurately than Google's Chirp on every set in the study, from studio news to overlapping film dialogue.

Figures are Word Error Rate (%) — the share of words a system gets wrong, so lower is better. It is the metric the paper reports, kept here so the table can be checked against it line for line; the headline numbers above are its flip side, accuracy. Vatis at 4.4 WER on Antena 1 is 95.6% of words correct. Every score is zero-shot: no system was tuned on these recordings before it was measured.

Outlined values are the best score in their column.

Use cases

Use cases for audio to text transcription

View all customers

95%+ accuracy is not a marketing number. We benchmark our models against fresh datasets every week. When we say 95%, we mean it. Our LLMs are trained on diverse audio — accents, background noise, crosstalk — because real conversations aren't recorded in a studio.

Recorder

In a world full of unsearchable but crucial information living on TikTok, Instagram Reels, Facebook and YouTube lives, Vatis gave us, as journalists, the opportunity to collect, transcribe and search that information.

Without it, I would have to listen to thousands of hours of interviews, debates and streamed video with nothing but two ears, ten fingers and a headset.

You can also translate transcripts into 50+ languages with one click.

Can I edit and search within transcripts?

Yes. You can search for specific parts of a transcript and proofread or correct it directly in the editor.

Does the transcript show when each speaker is talking?

Yes. Transcripts carry timestamps so you can find specific moments in the audio or video, and they show when each speaker is talking.

How can I create subtitles for my audio files?

Upload your files and Vatis Tech automatically transcribes them. It can also translate transcripts and generate subtitles in 30+ languages, making your content accessible to a wider audience. Export subtitles as SRT — the format most video platforms expect — or as plain TXT, then add them to your videos on YouTube, Facebook and elsewhere.

Is my data secure and are my files confidential?

Yes. Vatis Tech uses end-to-end encryption and is fully GDPR compliant. Your files are processed securely and are never shared with third parties. For organizations with strict security requirements we offer on-premise deployment: transcription runs entirely on your own servers and no data leaves your infrastructure.

Do you have an API for developers?

Yes. The Vatis Tech Speech-to-Text API lets you integrate transcription, speaker diarization, audio intelligence and real-time streaming into any application, via Python, JavaScript or plain REST. It supports 50+ languages and includes character-level timestamps, audio-event tagging and custom model training. Visit our API documentation to get started.

Can I generate a transcript from a video?

Yes. Upload any video file (MP4, MKV, AVI, MOV, WebM) or paste a YouTube link, and our AI generates a complete transcript with timestamps and speaker labels. Export it as TXT, DOCX, PDF or SRT. It is the fastest way to turn video into text — videos of any length, in minutes rather than hours.
