Open the original (DOI 10.1145/3382039)- What it measures
- The task asked participants to find errors in their own dictated text using audio only. The result was not significantly different from sighted participants.
- What it does not show
- Audio-only error detection in a lab task with 12 blind participants. The finding means audio review alone misses many errors, whoever is listening.
