Languages

Supported languages for filler detection and transcription.

Audio enhancement

All audio enhancement features — noise reduction, silence trimming, mouth sounds, breath removal, normalization, studio sound — are language agnostic. They operate at the signal level and work regardless of what language is spoken.

Transcription

Transcription is powered by Whisper and supports 99 languages, including English, German, Spanish, French, Japanese, Chinese, Arabic, Hindi, Portuguese, Russian, Korean, Italian, Dutch, Polish, Turkish, and many more. The language is auto-detected from the audio.

Filler word removal

Filler word detection is language-aware.

We process all languages phonetically, not text-based. That means, if it works great for German, it will work with Swedish, Norwegian, and other languages with similar sound patterns.

It focuses on how things sound, not merely the language. Hence, it also adapts well to multiple accents.

This gives you better results in both filler words removal and transcription.
