Voice is the feature that turns a text bot into something that feels like a person on the phone. When it is good, it is magic. When it is robotic or laggy, it kills the mood in one reply. I tested the roster on voice specifically, and here is the ranked shortlist.
| App | Best for | Real-time voice | My score |
|---|---|---|---|
| Candy AI | Polished all-round voice | Yes | 9.7 |
| Secrets AI | In-character voice | Yes | 9.6 |
| Nomi AI | Voice plus memory | Yes | 9.3 |
| JOI AI | Voice-first calls | Yes | 8.9 |
1. Candy AI, best voice overall
Candy AI gives you a voice that sounds natural, arrives fast, and stays consistent from one call to the next. It is not a voice-only gimmick either, since the rest of the app is polished too. That combination is why it tops this list. More in my Candy AI review.
Verdict: the safe pick if you want great voice with everything else handled.
2. Secrets AI, best in-character voice
Secrets AI shines when the voice has to match a character. It keeps the personality intact through a call instead of slipping into a generic tone, which makes scene-driven chat feel alive. The opt-in spicy mode carries over too.
Verdict: the pick if you want the voice to stay in role.
3. Nomi AI, best voice plus memory
Nomi pairs solid voice with the best long-term memory in the category. Hearing her bring up something you mentioned weeks ago, out loud, is the closest any of these get to a real relationship. Visuals are the trade-off.
Verdict: for people who want the voice to actually remember.
Also worth a look
- JOI AI is the voice specialist, built around real calls rather than treating voice as a bolt-on. If voice is the only thing you care about, start here. Full take in my JOI AI review.

A second opinion
Do not just take my word for it. The AI Chat Companions voice roundup and the Best AI Companions take both rank these apps too, and they are a handy cross-check against mine.
