This original proposal has no paid validation. Speech models assist transcription but cannot establish intent, attitude or service quality.
Deliver samples rather than staff rankings
The buyer is a support lead seeking process improvement. Initial labels might include query type, explicit resolution, next actions and audio positions. Use agreed evaluation rules without inferring emotions, personality or blame.
Align interpretation through a small sample
Request lawfully obtained, authorized, anonymized recordings. Two reviewers label the same sample independently and revise guidance after discussing differences. Demonstrations should use fictional dialogue, never a previous client's recordings to acquire another.
Include disputed cases in service scope
Audio quality, overlapping voices and ambiguous rules increase labor. Specify sample scope, review, disputes and deletion in pricing. Outputs support process improvement or training preparation; personnel decisions and other uses require separate client assessment.
