The four steps above take about 10 minutes for an hour of audio — these details turn the raw transcript into a finished document.
Before You Upload: A 60-Second Checklist
Three small choices before uploading decide most of your transcript's quality. Upload the best version of the file you have — the original export beats anything re-compressed by a messaging app, and a higher-bitrate MP3 or an uncompressed WAV gives the AI more signal to work with. Pick the language actually spoken in the recording; a mismatched language setting is the fastest way to a useless transcript. And if several people speak, don't worry about marking them — speakers are detected and labeled automatically, though knowing roughly who's who will speed up your review.
Editor Habits That Pay Off
The review pass in step three goes fastest with two habits. First, trust your doubts: whenever a sentence reads oddly, click the suspect word and the audio plays from that exact moment — verifying takes two seconds, guessing costs accuracy. Second, fix systematically rather than randomly: proper nouns, company jargon, and technical terms cause most of the corrections, so handle them first. You can also add custom terms and definitions for Sonix to prioritize, which teaches it your vocabulary for every future upload rather than fixing the same name file after file.
Choosing the Right Export
Step four offers 30+ formats, and the destination decides the choice. A document someone will edit wants DOCX; a record wants PDF; a video needs SRT or VTT with the timing already built in. Researchers coding interviews export to NVivo with speakers and timestamps intact, and plain text serves everything else — from search indexes to pasting into another tool. Nothing about the choice is final: the same transcript can be exported to as many formats as you need, whenever you need them.
If the Transcript Comes Back Rough
A rough transcript is nearly always the audio talking: distant microphones, background noise, crosstalk, or heavy compression. The repair strategy is triage — fix the passages you actually need using click-to-listen rather than polishing every line, and let the rest stay rough. For the next recording, the fixes are physical, not digital: a closer microphone, a quieter room, and one voice at a time will do more for accuracy than any setting. Our audio clean-up guides in the articles library cover rescuing noisy recordings before you upload them.
