Audio Transcription
Automatic Speech Recognition (ASR) converts spoken audio into written text. Modern AI-powered transcription achieves near-human accuracy on clear speech and supports dozens of languages.
Factors Affecting Accuracy
- Audio quality — clear speech with minimal background noise is essential
- Microphone quality — good microphones reduce noise and distortion
- Speaker clarity — clear pronunciation, moderate speed
- Accents and dialects — models trained on diverse speakers perform better
- Technical jargon — specialized vocabulary may require model fine-tuning
Use Cases
- Meeting notes and interview transcripts
- Podcast and video caption generation
- Voice note conversion to text
- Accessibility captions for hearing-impaired viewers
- Searchable archives of recorded content
What is Word Error Rate (WER) in transcription?
WER measures transcription accuracy — it's the percentage of words that are incorrect (substitutions, deletions, insertions). Human transcriptionists achieve ~4% WER on clear audio. OpenAI's Whisper model achieves 2.7% on benchmark datasets. Real-world WER increases significantly with accents, background noise, and multiple speakers.
How do I improve transcription accuracy?
Record at 16 kHz or higher sample rate. Use a close-miked condenser microphone. Reduce background noise — use a quiet room or noise gate. Speak clearly at a moderate pace. For multi-speaker recordings, use diarization (speaker identification) features to attribute speech to correct speakers.
Is my audio data private when using this tool?
This tool uses the Web Speech API built into your browser, which processes audio locally or sends it to your browser vendor's servers (typically Google for Chrome). No audio data is sent to OmniDash servers. For sensitive recordings requiring maximum privacy, use a locally-running model like OpenAI Whisper on your own machine.
