Eleven v4 Turbo takes #1 on Artificial Analysis TTS leaderboard
The cheaper, faster Turbo variant beating its own flagship in blind human preference voting signals that latency and cost, not raw quality, now decide TTS purchases. Teams building voice agents or customer service bots can pick Turbo for roughly half the price of Eleven v4 while still topping the arena. Its US$40/1M characters undercuts Cartesia's Sonic 3.6 at US$49, though Gemini 3.8 Flash TTS remains far cheaper at US$16.49.
