VALL-E X: The Most Dangerous Scammy AI Voice Cloning Tool Now Open Source
In Brief
Microsoft’s VALL-E X zero-shot TTS model has been released open source, allowing users to explore advanced text-to-speech synthesis and voice cloning.
The model supports fluent speech synthesis in English, Chinese, and Japanese, zero-shot voice cloning, speech emotion control, zero-shot cross-lingual speech synthesis, accent control, and acoustic environment adaptation.
VALL-E X operates seamlessly on both CPU and GPU, with a 6GB GPU VRAM required for optimal performance.
An open-source implementation of Microsoft’s VALL-E X zero-shot TTS model has been unveiled, allowing users to delve into the realms of advanced text-to-speech synthesis and voice cloning. This development comes as an expansion of Microsoft’s initial research paper, which lacked the code or pre-trained models necessary for hands-on exploration. With this release, the technology community gains access to a powerful tool for next-generation TTS capabilities.
VALL-E X is an exceptional multilingual text-to-speech model introduced by Microsoft. While the original research paper was informative, it lacked practical application due to the absence of code or pre-trained models. To bridge this gap, the dedicated team took on the challenge of reproducing the results and training our own VALL-E X model. The result of our endeavors is now available to the public, enabling a broader audience to experience the transformative potential of cutting-edge TTS technology.
VALL-E X is marked by several groundbreaking functionalities:
- Multilingual TTS: The model supports fluent speech synthesis in three languages: English, Chinese, and Japanese. Users can experience natural and expressive speech synthesis across these languages.
- Zero-shot Voice Cloning: By recording a short 3 to 10-second sample of an unfamiliar speaker’s voice, VALL-E X has the capacity to generate personalized, high-quality speech that mirrors the speaker’s unique vocal characteristics.
- Speech Emotion Control: VALL-E X can infuse synthesized speech with specific emotions, adding a layer of expressiveness to the audio output that aligns with the provided acoustic prompt.
- Zero-shot Cross-Lingual Speech Synthesis: The model can produce personalized speech in a different language while retaining fluency and accent, expanding the linguistic horizons of monolingual speakers.
- Accent Control: VALL-E X offers accent experimentation, allowing users to create content with diverse accents, such as speaking Chinese with an English accent and vice versa.
- Acoustic Environment Adaptation: The model accommodates varying audio prompts, adapting to the acoustic environment of the input to deliver a natural and immersive speech generation experience.
Moreover, VALL-E X extends its support to Chinese and Japanese languages, boasting exceptional performance across all three languages.

The voice cloning capabilities of VALL-E X facilitate the creation of voice prompts using a person’s, character’s, or one’s own voice. A speech sample of 3 to 10 seconds, along with the transcript, is all that’s needed to craft a distinct voice prompt. A user-friendly graphical interface further simplifies interactions with VALL-E X, rendering voice cloning and multilingual speech synthesis an accessible endeavor.
Notably, VALL-E X operates seamlessly on both CPU and GPU (pytorch 2.0+, CUDA 11.7, and CUDA 12.0). The model’s efficient design ensures that a GPU VRAM of 6GB is sufficient for operation without offloading.
In comparison to the Bark model, VALL-E X offers several advantages:
- Lighter in weight, occupying only 3/4th of the space.
- Enhanced efficiency with a 4x speed boost.
- Superior quality in Chinese and Japanese languages.
- Cross-lingual speech synthesis without foreign accents.
- Easy voice cloning capabilities.
Regarding VRAM requirements, a 6GB GPU VRAM meets the criteria for running VALL-E X effectively. However, for longer text generation, the total length of the audio prompt and the generated audio must remain below 22 seconds to ensure optimal performance.
The open-source licensing of VALL-E X, governed by the MIT License, signifies a new era of accessibility and exploration in the realm of multilingual text-to-speech synthesis and voice cloning.
