Speaker separation improvements
Mavio’s speaker diarization engine — the model that works out when the speaker changes — has been rebuilt, with significantly better accuracy in challenging scenarios.Accuracy improvements
What changed
- Cleaner clustering — fewer cases of one person being split across two speaker labels, or two people being merged into one.
- Overlapping speech handling — significantly improved accuracy when two or more people speak simultaneously. The model now separates overlapping voices instead of attributing the segment to a single speaker.
- Accent robustness — the new model performs equally well across a wide range of accents and speaking styles.
People management
A new Speakers section in the dashboard lets you manage identified speakers:- View everyone you have labelled across your meeting library
- Merge duplicate people (e.g., “John” and “John Smith”)
- Correct a label with one click

Language features
- Auto-detection — Mavio automatically detects the spoken language. No manual configuration needed.
- Multi-language meetings — when participants speak different languages in the same meeting, Mavio identifies and transcribes each language correctly, switching inline as the conversation shifts.
- Translated summaries — regardless of the language spoken, you can generate summaries in any supported language. Record in Japanese, get your summary in English.
- Localized action items — action items are extracted in the original language and can be translated on demand.
Transcription accuracy varies by language. English, Spanish, French, German, Portuguese, Japanese, Korean, and Mandarin achieve 95%+ accuracy. Less common languages achieve 88-93% accuracy and will improve over time as the models are refined.
Additional improvements
- Faster processing — transcription pipeline optimized, reducing average processing time from 5 minutes to 3 minutes for a 60-minute meeting
- Improved timestamps — word-level timestamps are now accurate to within 200ms (previously 500ms)
- Custom vocabulary — add industry-specific terms, product names, and acronyms in Settings > AI > Custom vocabulary so Mavio transcribes them correctly
- API language parameter — specify the expected language in API calls for faster processing when the language is known in advance
