 "note": "Twi voices only; no separate English voices. 30 of 207 Twi pseudo-speakers were measured. Use twi-cs-* for text mixing English into Twi and twi-* for pure Twi -- the two rankings disagree sharply, so neither substitutes for the other. spk_0016 is the best code-switch voice yet 21st of 30 on pure Twi, while spk_0165 is 3rd on Twi and poor on code-switch. Training hours predicts neither. Unlisted speakers remain reachable by raw speaker index.",
