How it was tested

4,524 audio clips, split evenly between genuine and synthetic speech. Podonos scores submitted predictions against private labels.

These are the main benchmark results. The 8 kHz and 16 kHz telephone-audio tracks are separate evaluations.

Processing speed is the reciprocal of the reported real-time factor; systems use different hardware, analysis windows and service conditions.
