## What the story says

toby builds an application that provides real-time translation on video calls. It uses Cartesia as its voice provider for low-latency multilingual speech, regional accent control, and voice cloning of speakers.

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

> Cartesia consistently achieves sub-200ms latency across all languages, the fastest among providers without compromising quality. This enables seamless translation, making interactions indistinguishable from live, in-office conversations.

> Our goal at toby is to eliminate language barriers to enable global workforces. It’s an ambitious mission that requires our bar for a voice provider to be extremely high. Cartesia delivers the best multilingual model for us across the board—latency, quality, and localization control that no other provider has.
