The Auto-Detect option identifies the spoken language automatically — no manual selection required.
How to Get the Best Transcription Results
For highest accuracy, use clear audio recordings with minimal background noise. Single-speaker audio transcribes more accurately than multi-speaker conversations. Recordings at 16kHz or higher sample rate produce better results than very low bitrate files. If your recording has significant background noise, consider using audio editing software to reduce noise before uploading.

Use a Good Microphone
Recordings made with a quality microphone or headset produce significantly higher accuracy than phone speaker or built-in laptop mic recordings.
Reduce Background Noise
Record in a quiet room. Background music, fan noise, or crowd sounds reduce accuracy. Use noise-reduction software if your recording already has noise.
Speak at a Natural Pace
Speak clearly at a moderate speed. Very fast speech or heavy mumbling reduces accuracy. Enunciate clearly, especially for technical terms or names.
Use High-Quality Audio Files
Use WAV or FLAC for best quality. MP3 at 128kbps or higher works well. Avoid heavily compressed files (below 64kbps) for important recordings.
Select the Right Language
If you know the language of the audio, select it manually instead of using Auto-Detect. This improves accuracy, especially for accented speech.
Trim Long Silences
Trim very long silent sections or dead air from recordings before uploading. This speeds up processing and keeps the transcript cleaner.
