([source](https://news.ycombinator.com/item?id=47262482)) "PersonaPlex is still interesting although it was looking like we would need to fine tune it" ([source](https://news.ycombinator.com/item?id=48834546)) "PersonaPlex totally seems like the future." ([source](https://news.ycombinator.com/item?id=48016344)) - Single model handles voice and prosody (1 comment in the sample): "the go to solution is PersonaPlex from Nvidia based upon Moshi" ([source](https://news.ycombinator.com/item?id=48835914)) ## What people warn about - Choppy, slow, or inaccurate performance (3 comments in the sample): "this full duplex architecture is still a bit off in terms of giving you good accuracy/performance" ([source](https://news.ycombinator.com/item?id=47259510)) "it was absolutely terrible. Around 10 seconds for each reply, and even then it was saying something totally unrelated." ([source](https://news.ycombinator.com/item?id=47261240)) "couldn't get even PersonaPlex to run properly (without choppiness/latency" ([source](https://news.ycombinator.com/item?id=46794156)) - No text output alongside audio (3 comments in the sample): "it lacks the ability to have a silent text stream output" ([source](https://news.ycombinator.com/item?id=47259192)) "If the model cannot emit both text and audio at the same time, to enable tools, it’s not really useful at all for voice agents." ([source](https://news.ycombinator.com/item?id=47260818)) "we have to also separately transcribe because it does not also provide what the person said" ([source](https://news.ycombinator.com/item?id=47267163)) - Limited intelligence without tool calls (2 comments in the sample): "7b can't be very intelligent on its own, and for anything useful, you'd need tool-calls" ([source](https://news.ycombinator.com/item?id=47261323)) "in my test it was oddly dumb and unable to follow instructions" ([source](https://news.ycombinator.com/item?id=47035625)) - Gets stuck, stutters, or rambles (1 comment in the sample): "it's really easy to get PersonaPlex stuck in a death spiral - talking to itself, stuttering and descending deeper and deeper into total nonsense" ([source](https://news.ycombinator.com/item?id=47259992)) ## Other voice AI models people recommend - [GPT-Live](https://hackerapproved.com/p/gpt-live/): 47 recommend, 21 mixed, 45 criticize - [Gemini Live](https://hackerapproved.com/p/gemini-3-8-live/): 40 recommend, 9 mixed, 23 criticize - [Sesame voice demo](https://hackerapproved.com/p/sesame/): 5 recommend, 0 mixed, 1 criticize ## The badge A product earns the Hacker Approved badge when at least 10 people recommend it, recommenders outnumber critics at least 2 to 1 (mixed feelings count toward neither side), it was recommended in at least 4 of the 12 months and in at least 5 different threads, and no single thread supplies more than half of the people who recommend it.
