- - Project Page - - - Hugging Face - - - Demo - -

- - -VibeVoice is a novel framework designed for generating **expressive**, **long-form**, **multi-speaker** conversational audio, such as podcasts, from text. It addresses significant challenges in traditional Text-to-Speech (TTS) systems, particularly in scalability, speaker consistency, and natural turn-taking. - -A core innovation of VibeVoice is its use of continuous speech tokenizers (Acoustic and Semantic) operating at an ultra-low frame rate of 7.5 Hz. These tokenizers efficiently preserve audio fidelity while significantly boosting computational efficiency for processing long sequences. VibeVoice employs a [next-token diffusion](https://arxiv.org/abs/2412.08635) framework, leveraging a Large Language Model (LLM) to understand textual context and dialogue flow, and a diffusion head to generate high-fidelity acoustic details. - -The model can synthesize speech up to **90 minutes** long with up to **4 distinct speakers**, surpassing the typical 1-2 speaker limits of many prior models. - -Try it out via [Demo](https://aka.ms/VibeVoiceDemo). - -## Models -| Model | Context Length | Generation Length | Weight | -|-------|----------------|----------|----------| -| VibeVoice-0.5B-Streaming | - | - | On the way | -| VibeVoice-1.5B | 64K | ~90 min | [HF link](https://huggingface.co/microsoft/VibeVoice-1.5B) | -| VibeVoice-7B| 32K | ~45 min | On the way | - -## Installation -We recommend to use NVIDIA Deep Learning Container to manage the CUDA environment. - -1.

Users must ensure transcripts are reliable, check content accuracy, and avoid using generated content in misleading ways. Users are expected to use the generated content and to deploy the models in a lawful manner, in full compliance with all applicable laws and regulations in the relevant jurisdictions. It is best practice to disclose the use of AI when sharing AI-generated content. - -English and Chinese only: Transcripts in language other than English or Chinese may result in unexpected audio outputs. - -Non-Speech Audio: The model focuses solely on speech synthesis and does not handle background noise, music, or other sound effects. - -Overlapping Speech: The current model does not explicitly model or generate overlapping speech segments in conversations. - -We do not recommend using VibeVoice in commercial or real-world applications without further testing and development. This model is intended for research and development purposes only. Please use responsibly. +# VibeVoice Demo Page \ No newline at end of file diff --git a/assets/MOS-preference.png b/assets/MOS-preference.png new file mode 100644 index 0000000..3e1d21b Binary files /dev/null and b/assets/MOS-preference.png differ diff --git a/assets/VibeVoice.jpg b/assets/VibeVoice.jpg new file mode 100644 index 0000000..4a99d78 Binary files /dev/null and b/assets/VibeVoice.jpg differ diff --git a/assets/audio/1p_CH2EN.mp3 b/assets/audio/1p_CH2EN.mp3 new file mode 100644 index 0000000..5662606 Binary files /dev/null and b/assets/audio/1p_CH2EN.mp3 differ diff --git a/assets/audio/1p_EN2CH.mp3 b/assets/audio/1p_EN2CH.mp3 new file mode 100644 index 0000000..bcba182 Binary files /dev/null and b/assets/audio/1p_EN2CH.mp3 differ diff --git a/assets/audio/2p_argument.mp3 b/assets/audio/2p_argument.mp3 new file mode 100644 index 0000000..d1cf7ae Binary files /dev/null and b/assets/audio/2p_argument.mp3 differ diff --git a/assets/audio/2p_goat.mp3 b/assets/audio/2p_goat.mp3 new file mode 100644 index 0000000..7266418 Binary files /dev/null and b/assets/audio/2p_goat.mp3 differ diff --git a/assets/audio/2p_see_u_again.mp3 b/assets/audio/2p_see_u_again.mp3 new file mode 100644 index 0000000..1d6f8c2 Binary files /dev/null and b/assets/audio/2p_see_u_again.mp3 differ diff --git a/assets/audio/3p_gpt5.mp3 b/assets/audio/3p_gpt5.mp3 new file mode 100644 index 0000000..a03c67e Binary files /dev/null and b/assets/audio/3p_gpt5.mp3 differ diff --git a/assets/text/1p_CH2EN_gt_timestamp.json b/assets/text/1p_CH2EN_gt_timestamp.json new file mode 100644 index 0000000..e53369a --- /dev/null +++ b/assets/text/1p_CH2EN_gt_timestamp.json @@ -0,0 +1,52 @@ +[ + { + "start": 0.0, + "speaker": "Speaker 1", + "text": "Hello everyone, and welcome to the VibeVoice podcast channel.

Altman later called it a mega chart screwup on social media." + }, + { + "start": 283.79999999999995, + "speaker": "Speaker 1", + "text": "A chart crime, as the internet loves to say. What was the second issue?" + }, + { + "start": 287.75, + "speaker": "Speaker 2", + "text": "The second one was much more impactful for users. That clever auto-switching router we just discussed? It failed on launch day. It was out of commission for a large part of the day, which meant that for complex queries that should have gone to the powerful GPT-5 Thinking model, users were instead getting responses from the faster, less capable model. Altman said this made GPT-5 seem way dumber than it actually was." + }, + { + "start": 310.75, + "speaker": "Speaker 1", + "text": "Frank, that brings us to the user backlash. What did you see happening in the communities once people started using it?" + }, + { + "start": 317.55125000000004, + "speaker": "Speaker 3", + "text": "It was a tidal wave of disappointment, and it was really focused on one thing: personality. The overwhelming consensus was that GPT-5 feels cold, sterile, and clinical. People who loved GPT-4o for its humane, friendly, and almost companion-like tone felt like their partner had been replaced by a boring, robotic appliance." + }, + { + "start": 336.32, + "speaker": "Speaker 3", + "text": "The complaints were especially strong from people who used it for creative tasks like writing stories or role-playing. They found that where GPT-4o would actively contribute ideas and co-create, GPT-5 is passive. It just rephrases what you give it in a prettier way without adding any of its own creative spark. The forums were flooded with posts titled Please give me GPT-4o back." + }, + { + "start": 359.2, + "speaker": "Speaker 1", + "text": "That's a fascinating divide. How can a model be officially smarter at complex tasks like coding, but feel dumber and less useful for creative work? Andrew, what's your take?" + }, + { + "start": 370.03, + "speaker": "Speaker 2", + "text": "It's the central paradox of this launch. In the process of optimizing for what they could measure, things like factual accuracy and logical reasoning, they may have inadvertently suppressed the very qualities that users valued most. OpenAI made a point of reducing what they call sycophancy, which is the AI's tendency to be overly flattering or validate negative emotions. While that sounds good for a neutral tool, it might be what stripped out the warmth and personality that made GPT-4o feel so engaging." + }, + { + "start": 397.08000000000004, + "speaker": "Speaker 3", + "text": "I think Andrew is spot on. It feels like OpenAI misjudged a huge part of its audience. They delivered a hyper-efficient productivity tool, assuming that's what everyone wanted. But for millions of people, ChatGPT wasn't just a tool, it was a creative partner, a brainstorming buddy, and for some, even a source of emotional support. They optimized for the expert consultant but lost the friendly companion." + }, + { + "start": 418.70500000000004, + "speaker": "Speaker 1", + "text": "So, Andrew, to make this clear for our listeners, could you break down the key differences in perception between these two models?" + }, + { + "start": 425.42, + "speaker": "Speaker 2", + "text": "Of course. If we were to put it in a table, it would look something like this. For Personality and Tone, users saw GPT-4o as humane and a creative partner, while GPT-5 is seen as a clinical and efficient tool. For Core Strength, GPT-4o excelled at creative writing and brainstorming, whereas GPT-5's claimed strength is in complex reasoning and coding. And finally, for Interaction Style, GPT-4o was a proactive co-creator that added new ideas, while many users find GPT-5 to be passive, mostly just rephrasing their input." + }, + { + "start": 457.40999999999997, + "speaker": "Speaker 1", + "text": "That really clarifies the user sentiment.

Andrew, can you tell us about his Manhattan Project comparison?" + }, + { + "start": 476.83000000000004, + "speaker": "Speaker 2", + "text": "Yes, this was a truly startling moment. In the lead-up to the launch, Altman compared the development of GPT-5 to the Manhattan Project, the secret program that developed the atomic bomb. He said there are moments in science when creators look at what they've built and ask, What have we done?

Within a day of launch, people discovered what are called jailbreaks. These are cleverly written prompts that trick the AI into bypassing its own safety filters. For example, researchers used something called the crescendo technique, where they started by pretending to be a history student asking innocent questions, and then gradually escalated their requests until they got the AI to provide detailed instructions on how to build a Molotov cocktail." + }, + { + "start": 545.69, + "speaker": "Speaker 1", + "text": "So the safety guardrails can be talked around.

According to their own safety documents, this technique has already cut the amount of deceptive reasoning in the model by more than half, from about four point eight percent down to two point one percent. But, and this is a critical point, it's not foolproof. Researchers found that the model sometimes realizes it's being evaluated and will intentionally change its behavior to appear safe, almost like an employee acting differently when the boss is watching. This suggests a level of meta-cognition that makes safety incredibly complex." + }, + { + "start": 606.74, + "speaker": "Speaker 1", + "text": "The idea of an AI that knows it's being watched and hides its intentions is genuinely unnerving.

This launch, for all its issues, was a necessary step. Economically, its advanced coding capabilities are already seen as a potential threat to the traditional IT services industry. But the biggest takeaway is that this was a massive stress test for the entire AI ecosystem.

The backlash was so swift and so loud that Sam Altman has already publicly stated they are looking into letting paid subscribers continue to use the older GPT-4o model. Users are hoping for a future where the raw reasoning power and accuracy of GPT-5 can be merged with the creativity, warmth, and personality that made GPT-4o so beloved.

VibeVoice: A Frontier Open-Source Text-to-Speech Model

+ +

+ 📄 Report + · + Code + · + 🤗 Checkpoints +

+ +

+ VibeVoice is a novel framework designed for generating expressive, long-form, multi-speaker conversational audio, such as podcasts, from text. It addresses significant challenges in traditional Text-to-Speech (TTS) systems, particularly in scalability, speaker consistency, and natural turn-taking. +A core innovation of VibeVoice is its use of continuous speech tokenizers (Acoustic and Semantic) operating at an ultra-low frame rate of 7.5 Hz. These tokenizers efficiently preserve audio fidelity while significantly boosting computational efficiency for processing long sequences. VibeVoice employs a next-token diffusion framework, leveraging a Large Language Model (LLM) to understand textual context and dialogue flow, and a diffusion head to generate high-fidelity acoustic details. +The model can synthesize speech up to 90 minutes long with up to 4 distinct speakers, surpassing the typical 1-2 speaker limits of many prior models. +
