speech synthesis

Spark-TTS is an efficient text-to-speech synthesis model based on a large language model with the characteristics of single-stream decoupled speech tokens. It leverages the power of large language models to reconstruct audio directly from code predictions, omitting additional acoustic feature generation models, thereby increasing efficiency and reducing complexity. The model supports zero-shot text-to-speech synthesis and is able to switch scenarios across languages ​​and codes, making it ideal for speech synthesis applications that require high naturalness and accuracy. It also supports virtual voice creation, and users can generate different voices by adjusting parameters such as gender, pitch, and speaking speed. The background of this model is to solve the problems of low efficiency and high complexity in traditional speech synthesis systems, aiming to provide efficient, flexible and powerful solutions for research and production. Currently, the model is mainly geared toward academic research and legitimate applications, such as personalized speech synthesis, assistive technology, and language research.

IndexTTS is a GPT-style text-to-speech (TTS) model, mainly developed based on XTTS and Tortoise. It can correct the pronunciation of Chinese characters through pinyin and control pauses through punctuation. This system introduces a character-pinyin hybrid modeling method in the Chinese scene, which significantly improves training stability, timbre similarity, and sound quality. Additionally, it integrates BigVGAN2 to optimize audio quality. The model was trained on tens of thousands of hours of data and outperformed currently popular TTS systems such as XTTS, CosyVoice2, and F5-TTS. IndexTTS is suitable for scenarios that require high-quality speech synthesis, such as voice assistants, audiobooks, etc. Its open source nature also makes it suitable for academic research and commercial applications.
