Gemini Label Verification

Every sample was sent to Gemini 3.1 Flash Lite for two independent tasks:

1. Match scoring: Audio + original prompt label sent together. Model rates how well the label matches: 0 (not at all), 1 (slightly), 2 (very well).
2. Dense captioning: Audio sent alone (without the label). Model produces a concise technical description of the vocal burst.

Match Score	Meaning	Count	Percentage
2	Very well — label accurately describes audio	15,082	93.2%
1	Slightly — somewhat related but not accurate	160	1.0%
0	Not at all — label is completely wrong	933	5.8%

15,242 / 16,175 samples (94.2%) verified as valid (match score 1 or 2).

Total verification cost: /bin/bash.97 (32,350 API calls across 100 parallel threads in ~21 minutes).
