Speko rates its naturalness at 1,569 Elo from blind A/B votes on phone-agent lines (13th highest of the 43 models Speko rates). In the Artificial Analysis Speech Arena it holds 1,037 ±12 Elo (95% interval), 73rd highest of the 98 models Artificial Analysis rates; scores whose intervals overlap are a tie. In its Customer Service category, Artificial Analysis places it 73rd, at 1,051 Elo.
Speko's pronunciation test on numbers, dates and currency scores it 0.22 on a 0-to-1 scale (22nd highest of the 30 models Speko scores). This is the accuracy measure used here; Coval's word error rate separates models too little to compare them.
