description: Introduction:

CVoiceFake (Full) encompasses five common languages (English, Chinese, German, French, and Italian) and utilizes multi-advanced and classical voice cloning techniques (Parallel WaveGAN, Multi-band MelGAN, Style MelGAN, Griffin-Lim, WORLD, and DiffWave) to produce audio samples that bear a high resemblance to authentic audio.



Parallel WaveGAN: As a non-autoregressive vocoder-based model, Parallel WaveGAN produces high-fidelity audio rapidly, ideal for efficient and quality deepfake generation.

Multi-band MelGAN: Multi-band MelGAN is a variant of MelGAN that divides the frequency spectrum into sub-bands for faster and more stable multi-lingual vocoder training, enhancing the robustness and scalability of the dataset.

Style MelGAN: Style MelGAN is designed to capture fine prosodic and stylistic nuances of speech, making it particularly compelling for deepfake applications that require high levels of expressivity and variation in speech synthesis.

Griffin-Lim: This algorithm reconstructs waveforms from spectrograms using an iterative phase estimation method. Though less high-fidelity than neural vocoders, it serves as a traditional baseline for comparing deepfake generation.

WORLD: WORLD is a statistical parameter-based voice synthesis system that offers fine control over the spectral and prosodic features of the synthesized audio. Its fine manipulation is useful for crafting the nuanced variations needed in deepfake datasets.

We have also built the SOTA diffusion-based deepfake audio (DiffWave); please contact the author at xinfengli@zju.edu.cn if you are interested in the dataset, particularly the DiffWave portion. Furthermore, any additional discussions are welcomed.DiffWave: DiffWave is a diffusion probability model for waveform generation. It converts the white noise signal into structured waveform through a Markov chain, capable of both conditional and unconditional generation tasks. DiffWave represents the advanced synthesis method for its fast synthesis speed and high synthesis quality.


🔥 News:

Please note that we recently released our DiffWave subset in Version 2 (DiffWave is the 6th voice cloning technique added in the extended TDSC'26 version (https://ieeexplore.ieee.org/document/11216043). This is an update from Version 1 (our CCS'24 version includes 1st to 5th voice cloning techniques). You can download the file named CVoiceFake_Large_diffwave_update.tar.gz.xx. After unzipping, you'll find the file structure remains the same as before.
