- Why it was chosen
- Audio-tag controls, Elo scores and access across platforms help assess controllability in speech generation.
A model scores each item twice, independently, against one written standard, out of 100. An item is admitted only when the two scores add up to twice the threshold. The threshold is set per source tier.
