Question 1

How is the quality score measured?

Accepted Answer

It comes from Artificial Analysis, an independent benchmark. Listeners hear two clips of the same line without being told which model produced either, and pick the one they prefer. Sonic 3.6 rates above both Resemble AI models on the board, Chatterbox HD and Chatterbox.

Question 2

How many languages does Cartesia support?

Accepted Answer

44 languages from one model, including English, Spanish, French, German, and Japanese. Accents are calibrated per region rather than bolted onto an English model. Resemble AI lists 23+ languages for Chatterbox Multilingual.

Question 3

Can I use my own voice with Cartesia?

Accepted Answer

Yes. An instant clone takes 10 seconds of audio and a professional clone takes 30 minutes, both self-serve on the public API.

Question 4

How long does it take to switch from Resemble AI?

Accepted Answer

One to two weeks for most teams. Cartesia is integrated into the major voice agent platforms and every model is on the public API, so there is no platform to move onto and nothing to unpick later.

Listeners rate Cartesia's Sonic 3.6 above both Resemble AI Chatterbox models.
