Guys, today I must share with you Microsoft's open - source real - time speech model VibeVoice - Realtime - 0.5B 👏!

Previously, when using traditional TTS models, the startup time was often 1 - 3 seconds. That kind of lag really affected the experience 😫. This was the pain point in our use of speech models. However, VibeVoice - Realtime - 0.5B perfectly solves this problem. On average, it only takes 300 milliseconds from text input to sound output, almost with zero delay. It's just like having a conversation with a real person. As soon as you type, the other side starts to respond. It's extremely smooth 💯.

Its capabilities don't stop there! It can generate an ultra - long audio of up to 90 minutes at one time, and the whole process is smooth and natural, just like a professional broadcaster reading. Moreover, it natively supports up to 4 characters to have a conversation simultaneously, with smooth emotion transitions. The built - in emotion perception module can automatically recognize emotions without manual annotation, and it's ready to use as soon as you get it 👍.

I tried it myself. I used it on HuggingFace to read the first chapter of "The Three - Body Problem". There was no voice break, and the effect was excellent. Its English performance is close to the commercial level, and it's also very good in Chinese. Although there is still room for improvement in the handling of some polyphonic characters and neutral tones, the official will release a fine - tuned version. With its lightweight design, it can run at real - time speed on an ordinary laptop and can already be integrated into many tools.
Currently, this model has been completely open - sourced and supports commercial use. There are also many interesting demos in the community. Guys, don't miss it. Hurry up and give it a try 👇!
