Voice and cloning

For voice, I look at human preference, price per million characters, streaming latency and whether pt-BR voices exist. Demo samples and a MOS declared by the vendor stay out. Cloning requires consent and a reading of the use policy; a Brazilian accent and rights enter that conversation before the rank.

I did not find, in this pass, an independent arena devoted only to voice cloning.

What I cite is an isolated point from Artificial Analysis, in the latest version we checked: Eleven v4 led the Speech Arena with an Elo of 1338, at US$80 per million characters, and Qwen-Audio-3.1-TTS-Plus sat 3rd, at 1299. Source: Artificial Analysis (artificialanalysis.ai). There is a price divergence I have not reconciled: the same reading lists Qwen at US$19.31 per million, while Model Studio in Singapore lists qwen-audio-3.1-tts-plus at US$0.3 per 10,000 characters, which equals US$30 per million. It may be a different region or a different cut.

Open source board

Voice has no number board. Anything from Artificial Analysis stays as a citation in the text, with the index version.
