Summary written by usedby from the source page, in English. The figures are those of Cartesia and Telli, not ours.

> Integration with telli’s existing stack allowed their engineering team to implement Cartesia as their TTS provider with minimal effort—taking only about one hour to get up and running.

> The voice is at the heart of what we do, so it has to be just right. With Cartesia and their voice cloning capabilities, we’ve been able to reach a new level of quality. Throughout, they’ve been a great partner to start with and to scale with. It’s an easy-to-use text-to-speech tool that we’d definitely recommend for achieving brand-aligned, highly engaging conversations.
