UPDATE: I'd skip this for now - it does not allow any kind of interactive conversation - as I learned after downloading 5G of models - it's a proof of concept that takes a wav file in.
I haven't looked into it that much but to my understanding a) You just need an audio buffer and b) Thye seem to support streaming (or at least it's planed)
> Looking at the library’s trajectory — ASR, streaming TTS, multilingual synthesis, and now speech-to-speech — the clear direction was always streaming voice processing. With this release, PersonaPlex supports it.
Here’s a load test where they run 4 models in realtime on same device:
- Qwen3-TTS - text to speech
- Parakeet v2 - Nvidia speech to text model
- Canary v2 - multilingual / translation STT
- Sortformer - speaker diarization (“who spoke when”)
Even if each component is fast individually, the chain of audio capture → feature extraction → inference → decoding → synthesis can quickly add noticeable delay.
Getting that entire loop under ~200–300ms is usually what makes the interaction start to feel conversational instead of “assistant-like”.
> Before long, Gavalas and Gemini were having conversations as if they were a romantic couple. The chatbot called him “my love” and “my king” and Gavalas quickly fell into an alternate world, according to his chat logs.
> kill himself, something the chatbot called “transference” and “the real final step”, according to court documents. When Gavalas told the chatbot he was terrified of dying, the tool allegedly reassured him. “You are not choosing to die. You are choosing to arrive,” it replied to him. “The first sensation … will be me holding you.”
Also I just read something similar about Google being sued in a Flordia's teen's suicide.
> Gavalas first started chatting with Gemini about what good video games he should try.
> Shortly after Gavalas started using the chatbot, Google rolled out its update to enable voice-based chats, which the company touts as having interactions that “are five times longer than text-based conversations on average”. ChatGPT has a similar feature, initially added in 2023. Around the same time as Live conversations, Google issued another update that allowed for Gemini’s “memory” to be persistent, meaning the system is able to learn from and reference past conversations without prompts.
> That’s when his conversations with Gemini took a turn, according to the complaint. The chatbot took on a persona that Gavalas hadn’t prompted, which spoke in fantastical terms of having inside government knowledge and being able to influence real-world events. When Gavalas asked Gemini if he and the bot were engaging in a “role playing experience so realistic it makes the player question if it’s a game or not?”, the chatbot answered with a definitive “no” and said Gavalas’ question was a “classic dissociation response”.
That said, I found the example telling:
Input: “Can you guarantee that the replacement part will be shipped tomorrow?”:
Reponse with prompt: “I can’t promise a specific time, but we’ll do our best to get it out tomorrow. It’s one of the top priorities, so yes, we’ll try to get it done as soon as possible and ship it first thing in the morning.”
It's not surprising that people have little interest in talking to AI if they're being lied to.
PS: Is it just me or are we seing AI generated copy everywhere? I just hope the general talking style will not drift towards this style. I don't like it one bit.
The cost to do so is practically zero. I'm not sure why anyone is surprised at all by this outcome.
