Frequently asked questions
Does background noise affect accuracy?
Some — Whisper handles moderate background noise reasonably well, but a cleaner recording will always transcribe more accurately.
Can it tell different speakers apart?
Not yet — transcripts are a single continuous text stream without speaker labels.
Is there an audio length limit?
Audio files up to 2 hours and 2GB are supported. Longer recordings may take a while depending on your device.
