Common Questions
How accurate is the transcription?
Accuracy depends on audio quality and clarity. For clear speech with minimal background noise, expect 90%+ accuracy. Whisper handles accents well but may struggle with heavy noise, overlapping speakers, or very technical terminology.
Why does the first transcription take so long?
The first use downloads the Whisper Tiny model (~150MB). This is cached by your browser, so subsequent transcriptions start much faster. Larger files also take longer to process.
What languages are supported?
Currently supported: English, Spanish, French, German, Italian, Portuguese, Chinese, Japanese, Korean, and Russian. More languages may be added in future updates.
Is there a file size or duration limit?
No enforced limit, but very long audio (30+ minutes) may strain device memory. For best results, keep files under 10 minutes or split longer audio into segments.
Can this transcribe multiple speakers?
The current model doesn't distinguish between speakers. All speech is transcribed as continuous text without speaker labels or timestamps.
