Automatic transcription is very good and getting better, but "very good" isn't "flawless." Knowing what moves the needle — and what to check afterward — saves you from either over-trusting or over-editing the result.
What accuracy actually depends on
The single biggest factor is audio quality, not the tool. In rough order of impact:
- Clarity of speech — clear, paced speakers transcribe near-perfectly; mumbling and fast crosstalk don't.
- Background noise — music, traffic, room echo, and HVAC hum all degrade results.
- Number of speakers — one voice is easy; four people interrupting each other is hard.
- Accents and domain jargon — strong accents and specialized terminology raise the error rate, especially for names and acronyms.
- Recording setup — a lapel mic beats a laptop across the room every time.
Where errors show up
When mistakes happen, they cluster in predictable places: proper nouns, brand and product names, technical terms, numbers, and the boundaries where speakers overlap. General prose is usually clean.
Tip: Every finished VTS transcript shows an estimated confidence score. Use it to triage — high confidence needs a skim, low confidence needs a closer read against the audio.
A fast review pass
You don't need to re-listen to everything. Search the transcript for the names and terms you know appear, fix those, then read the low-confidence sections against the recording. For most clean audio that's a few minutes of cleanup on a transcript that would have taken an hour to type.
The honest summary: expect a strong draft, not a finished document. On good audio the draft is nearly final; on bad audio, fix the audio before you fix the text.
