Artificial Analysis Launches Controlled Voice Arena TTS Leaderboard

Artificial Analysis has launched the Controlled Voice Arena, a text-to-speech (TTS) leaderboard featuring a public voting arena. To isolate model capability from voice preference, the evaluation uses 8 uniformly cloned voices to test different TTS models. The organization has also published its methodology and the cloned voice samples used for testing.
