Output Formats Explained
TXT — Plain Text
Simple text without timestamps. Best for meeting notes, lecture transcripts, interviews, and any case where you need the spoken words as readable text. Easy to paste into documents, emails, or notes.
SRT — SubRip Subtitles
The most widely supported subtitle format. Includes numbered segments with start/end timestamps. Works with VLC, Premiere Pro, DaVinci Resolve, YouTube uploads, and virtually every video player and editor.
VTT — Web Subtitles
The HTML5 web standard for video captions. Used with the <track> element in web video players. Supports styling and positioning. Choose VTT when building web applications or embedding subtitles in websites.
Tips for Better Transcription
AI transcription accuracy depends heavily on the quality of your audio. Here are practical tips to get the best results:
- Use clear audio — recordings with minimal echo, distortion, or clipping produce the most accurate transcriptions. If possible, use a decent microphone close to the speaker.
- Minimize background noise — music, traffic, air conditioning, and other ambient sounds interfere with speech recognition. Record in a quiet environment when you can.
- Single speaker works best — the AI handles one speaker at a time most accurately. Overlapping conversations or crosstalk between multiple speakers may produce errors or merged text.
- Speak at a natural pace — very fast speech or mumbling reduces accuracy. Clear, natural-paced speech is ideal.
- Choose Best quality for difficult audio — the Best quality mode uses more processing passes and handles accents, background noise, and technical vocabulary better than Fast mode.
- Specify the language when you know it — while Auto-detect works well, explicitly selecting the language can improve accuracy, especially for less common languages or audio with code-switching.
