Pro Tips for Better Transcription Results
Professional techniques to maximize transcription accuracy and streamline your audio to text workflow
Provide Context When Possible
When uploading files, include relevant metadata like speaker names, topic, or industry. This context helps our AI better understand technical terminology and specialized vocabulary specific to your field.
Review and Edit Transcripts
While our AI achieves up to 99% accuracy, always review transcripts for critical applications. Use the time-synced playback feature to quickly verify unclear sections by listening to the original audio.
