An unintelligible utterance is input whose meaning cannot be determined reliably. In conversational logs, it may result from keyboard mashing, severe typos, speech-to-text errors, or captured background conversation. section 4.4.2
Recognizing the failure
Inputs such as “does it school,” a long fragment from a caller’s background conversation, or “klewtkhaccalifornia liense” are too incoherent for dependable intent assignment. section 4.4.2
Handle suspected unintelligible utterances during candidate review:
- Make a quick usability decision rather than over-analyzing; discard the input if no determination is possible within about a minute. section 4.4.2
- Exclude clearly unintelligible inputs from blind test sets. section 4.4.2
- Set recurring speech-transcription or environmental-noise patterns aside for further evaluation or referral to the appropriate team. section 4.4.2
