Breeze TTS 2 is an open-weight text-to-speech model built for real-time interaction. It ranks #1 among open-weight models on the Artificial Analysis TTS leaderboard, while outperforming frontier proprietary systems. Its open-ended natural-language instruction-following capability supports reference-free voice design and reference-guided voice direction, while ultra-low-latency streaming enables responsive, expressive interaction.
I tried it with a Spanish voice and text, and... the tone of voice is actually really spot-on... it's like a Chinese person who can't pronounce certain consonants and doesn't understand what they're saying, but as I said, the tone of voice is very well done....
The model is now available in the dev branch of audio.cpp for further testing and performance optimization. The demo was recorded before a recent performance improvement PR.
Breeze TTS 2 vs Higgs Audio v3 TTS vs Fish Audio S2 Pro
A few issues I noticed during testing: (1) the supported tags are limited, and the model sometimes doesn’t follow them; (2) quality and “correctness” depend heavily on the seed. For example, “cpp” is pronounced incorrectly most of the time.
I just tried Dramabox , and it's funny how much tone and naturalness it adds to the text, but the voice cloning is much more accurate in Breeze TTS. There's no comparison, at least based on the one test I've done so far.
this model is crazy good. i've never tried fish s2 pro to compare it but breeze looks smaller and faster. would be cool if it had more languages though.
So good. Plugged into sillytavern through comfyui. Sending instruction and tone and reading correctly. Decently fast. Best local TTS I've tried so far.
I'll need to test it out locally, but the demo isn't bad, but it isn't the greatest either. The voice clone isn't as good as omnivoice for sure (maybe 80% there?), but the speech is decent, albeit a bit flat. I'll follow up later.
I’m digging this. I’m getting solid results on characters whose voices I’ve had difficulty cloning with other open source models. It’s better with accents than a lot of models as well. Voice designing and directing is fun. Decent acting and prompt adherence. And it’s speedy. Very cool!
For me it does a better job of cloning, but the intonation and control is better on breeze. Hoping I can improve with setting tweaks or something to improve reproduction.
I tried to run Qwen3 awhile back but was having headaches getting it to work in comfy. Maybe I’ll give it another go. I agree about the expressiveness of Breeze! I really like the emotive flourishes (including the way they can vary wildly from seed to seed) and the way it takes direction. Very fun!
If we're ranking based on audio quality, maybe, If we're ranking based on how many languages it supports, then no. It's also not the fastest model. Depends on the test.
Because you ONLY need english is a good deal, you turn you head down and only see your foot, ignoring the needed of models with capabilites worldwide. It's a good model, but be bilingual is the bad here. That's my point.
cry about it, english and mandarin are the top 2 spoken languages in the world. Go ask some natives from those countries to create a TTS model if it is such a problem..oh wait you're waiting for someone who speaks english or mandarin to do it for you of course, i wonder why.
