Hello @Gabriel Garcia, how are you?
Your conclusion aligns with what I've seen in production.
AI Scoring today is much stronger for:
- semantic interpretation
- empathy
- compliance language
- conversational behavior
- than for deterministic acoustic analysis.
- Metrics like:
- greeting within X seconds
- silence thresholds
- interruption timing
- exact hold duration
- are still much more reliable using:
- Speech Analytics
- Acoustic Metrics
- Interaction Categories
- Topics/Programs
Prompt engineering can improve participant/context awareness, but it won't fully replace true timestamp/acoustic analysis because the LLM is primarily transcript-oriented.
I hope this answer is helpful to you.
Regards!

Subject: AI Scoring vs Acoustic Metrics for Time-Based QA Evaluations in Virtual Supervisor
Hello community,
We have been testing AI Scoring / Virtual Supervisor for QA automation and noticed some limitations around time-based evaluations.
Example:
- "Agent must greet within 10 seconds"
- "No excessive silence"
- "Dead air detection"
What we observed:
The AI seems heavily transcript-driven and not truly aware of acoustic timing or participant silence duration.
In some scenarios:
- customer speaks first
- agent remains silent
- but the AI still interprets the interaction as an active greeting/opening
This creates false positives for timing-based compliance rules.
Our current conclusion is:
- AI Scoring works very well for empathy, ownership, soft skills and conversational quality
- Acoustic/timestamp KPIs still belong to Speech Analytics / Topics / Acoustic Metrics
Curious how others are balancing:
- LLM-based evaluations
vs - deterministic acoustic metrics
Have you found effective prompt engineering strategies for timing-sensitive QA scenarios?
