## What the story says

EliseAI runs its voice agents for leasing, resident support and healthcare scheduling on Cartesia's Sonic models, working with Cartesia to tune regional and multilingual voices. It tests new voices through benchmarks, blind A/B tests, a limited production rollout and manual call audits.

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

> The regional voice test moved every northstar metric EliseAI tracked. Tour conversions rose 5%. Caller engagement rose 8%. Callers spoke 16% more words, which gives the agent more to work with and a better shot at solving the problem on the first call.

- **8%**: “Caller engagement rose 8%.”
- **16%**: “Callers spoke 16% more words, which gives the agent more to work with and a better shot at solving the problem on the first call.”
- **12.5%**: “In early testing, renters rated it 12.5% higher on voice naturalness than every previous model.”

> We run 5M+ voice calls a month helping people through eligibility, income verification, and recertification. Multilingual means we can now do it in their own language, after hours, when they need it, because the language you speak shouldn’t make housing harder to get.
