How does audio to text conversion work?
Upload your audio file, select the spoken language, and Sonix's AI converts it to text in minutes. Review in our editor, then export to your preferred format.
Upload MP3, WAV, M4A, or any audio format and get accurate text in minutes. Sonix's AI speech recognition delivers 99% accuracy with automatic punctuation, speaker identification, and word-level timestamps.










Manual transcription takes 4x the audio length. Sonix converts audio to text in minutes, freeing your team to focus on higher-value work.
Text transcripts are searchable. Find any moment in your audio instantly by searching the transcript—no more scrubbing through hours of recordings.
Share transcripts with colleagues, add comments, and collaborate on edits. Make your audio content accessible to your entire team.
Turn audio recordings into blog posts, social media content, meeting notes, or documentation. Extend the value of every recording.
Human transcription services can be costly and time-consuming, especially when you're regularly producing content. A professional transcriptionist charges $25 to $40 per hour and may take 48 hours or longer to complete an hour-long recording—requiring them to listen multiple times to ensure accuracy.
Sonix transcribes the same content in under five minutes with up to 99% accuracy, at a fraction of the cost. Thanks to artificial intelligence, Sonix produces more accurate transcripts than many manual services while eliminating long turnaround times. Transcribe as many files as you need, quickly and affordably.
For perfect results, all transcriptions require a little clean-up—especially with terms or phrases unique to your company or industry. These clean-ups are easily achieved with the Sonix in-browser editor.
The editor works like a word processor within your browser, synchronized perfectly with your source audio or video. Click any word to jump to that exact moment in the recording. Make changes, add speaker labels, and adjust timestamps without switching between programs. Once you're done editing, export your transcript in a variety of formats—Word, PDF, SRT, VTT, text, NVivo, or Adobe Audition session files—so you can incorporate the text into the next step of your workflow.
