Speed

TTFA = time to first audio (lower is better). RTF = real-time factor (× realtime; higher is better). Cold = first run after load; warm = subsequent runs. Pick a rig below — each shows its default-voice and cloning runs. Tables default to warm RTF, fastest first; click any column header to re-sort. Audio is on the Listen page.
