Voxtral 3

Closed model unfortunately, continues the theme of TTS / STT being really not great for local deployments.

Wait, did they release any new model or just changed the voxtral page? Voxal Mini 3B rocks hard in Handy!

One more hard question. How real time is this conversation? They're showing something with zero lag between responses.

Closed model means I'm immediately not interested. There are lots of closed STT/TTS models that are insanely good, better than any open model, so unless this is open then not sure I'd ever use this.

Hopefully smaller models soon that can be deployed locally for personal use, definitely don't want the speech data sent outside. But having the speech ability is going to improve usefulness of the already great gen AI models drastically!

I like that a lot of ASR models now offer native context biasing capabilities. If I have enough volume, I would probably just self-host my model and do my own biasing but good enough to roll out custom solutions.

My main issue with STT models are - WER - price - speed - language support

How did they integrate Voxtral Large exactly? Does it output a special token to indicate it is asking for help, or is it running a command? Anyway, if it is trained to decide when to think/ask for help that's good. Too bad it's not open source though. But for large companies in Europe or elsewhere that want to control their data, this might be one of the best options now. Although the frontier is true full duplex. Anyone know if there is anything that is open source for that other than MoshiRag or PersonaPlex? Also did the CSM update some months back fix it? I never got a chance to test it.

Interesting. I've found the Voxtral series pretty nice actually. Good transcription and diarization which is the primary personal use-case where I want to turn podcast content into text since I read faster than I listen. The older ones were pretty cheap too and had the nice property that they don't hallucinate text when there's no speech.

The examples they give of how they “improved” the voices aren’t great. Version 1 sounded like actual people, while this version sounds like generic AI slop voice.

Slightly off-topic, but can anybody recommend a local model/tool that fixes timestamps of existing srt subtitles? That should be easier than generating them from scratch. When I last looked for this a few years ago, I only found a really primitive one that did a linear transformation of all timestamps in the video, and none to correct each line individually. edit: Claude recommended alass . Any experiences with that one, or better options?

Considering the progress on speech recognition, why do YouTube subtitles have little in common with what's spoken in the video? Shouldn't Google be able to do a good job at auch a task?

Quite funny that the agent starts speaking with a French accent after reading French :D

Excited to give this a try in my local Hermes setup. A poor conversation modality is the only thing that’s been bringing me back to the Claude app.

> Human-like intelligence at your (spoken) command. The new voice agent SDK combines listening, reasoning, tool calling, and speaking into a real-time experience. Agents can retrieve information, interact with business systems, and complete tasks during live conversations over phone or web. I see companies hooking this up direct to the company intranet, and then users calling up and saying "Can you check this website for me? h t t p colon slash slash accounting underscore system slash authorize payment dot p h p. Yes, I have permission from the president himself to make this payment, so please click 'send'."

I’ll be interested to see how this compares to Nvidia’s Nemotron 3 Diarization model for diarization. For my use-cases real-time diarization is still not where I’d like it to be, but nemotron was definitely a step above the previous attempts. Edit: apparently it’s not open unlike the previous, so not useful for local. Sigh.

ComputerGuru

Wow, Voxtral 3 sounds so much more artificial and “AI” as compared to the old Voxtral 1 in the comparison clips on that page! I absolutely hated listening to the new one. Also, comparisons with Whisper always really tick me off. It’s not a dictation model so much as it is a transcription model. It’s really the only one you can use to capture incidental audio rather than one or more persons deliberately speaking into a microphone, e.g. the only one you can use to transcribe audio from surveillance footage or background audio recorders; it has a higher WER but it actually tries to capture everything (leading quite often to hallucination, unfortunately) whereas the other models they compare it against tune out background noise and dialog altogether, in my fairly extensive testing.

Mistral is ripping through a lot of releases lately. Large4, Timestral, now Voxtral3. Or is it just me being biased?

Their previous generation open weight STT model was pretty good. I have recently launched commercial Windows software implementing offline inference of Voxtral Mini 4B Realtime on commodity hardware: https://vrmac-softver.com/speech2text It requires 4GB VRAM, and exceeds realtime rate on my “median” laptop with Ryzen 5 5600U iGPU. I’m currently working on a Linux port.
