I record every meeting and interview. Transcribing a 1-hour recording used to take 4 hours of manual typing. AI transcription does it in 5 minutes with 95% accuracy.
Accuracy by Audio Quality
| Audio Quality | Expected Accuracy | Examples |
|---|---|---|
| Studio quality (close mic, quiet room) | 97-99% | Podcast recordings, professional interviews |
| Good quality (decent mic, some noise) | 93-97% | Zoom calls, phone recordings |
| Fair quality (built-in mic, noisy) | 85-93% | Lecture recordings, conference rooms |
| Poor quality (far from mic, heavy noise) | 70-85% | Outdoor recordings, crowded spaces |
| Multiple speakers overlapping | 60-80% | Group discussions, debates |
Tips for Better Transcription
- Clean the audio first. Use our Noise Remover before transcribing.
- Use a good microphone. A $30 USB mic beats any laptop built-in mic.
- Speak clearly. Enunciate and pause between sentences.
- One speaker at a time. Overlapping speech is the hardest challenge.
Output Formats
- Plain text. Just words, no timestamps.
- SRT subtitles. Text with timestamps for video.
- Timestamped transcript. Paragraphs with timestamps for meeting notes.
Transcribe your audio - AI-powered, free, instant.
