> **Key:** **The one-liner:** the most natural-sounding voice AI just landed on iPhone — the question is whether people actually keep talking to it.

**What happened.** On 28 May, **Sesame** released a public preview of its iPhone voice app in 39 countries, with four AI agents, built on its **Conversational Speech Model** — prized for sounding genuinely human and for keeping conversation flowing.
