You will learn to
Mark audible speech, uncertainty, and transcription inference separately.
Why this matters
Guessing an unclear word turns uncertainty into false training data.
Three things to remember
- Use timestamps for every issue.
- Keep spoken words separate from reviewer inference.
- Use the project's uncertainty convention consistently.
See one example
Task
Traffic noise masks one word in a sentence.
Weak approach
Guess the likely word from context.
Stronger approach
Mark the span unclear at the timestamp and preserve the surrounding words.
Why the stronger approach works
Faithful uncertainty is higher-quality data than a plausible guess.
Make something yourself
Create a three-line transcript review with timestamp, observed issue, and confidence.
A useful starting pointDo not invent missing speech. Use an explicit unclear marker.
