What is Spark-TTS-0.5B?
Spark-TTS-0.5B is an innovative text-to-speech model that leverages large language model technology to produce natural-sounding speech synthesis. Built on the Qwen2.5 architecture, it introduces a unique single-stream decoupled speech tokens approach that simplifies the traditional TTS pipeline while maintaining high-quality output.
Implementation Details
The model implements a streamlined architecture that directly reconstructs audio from LLM-predicted codes, eliminating the need for separate acoustic feature generation models. This approach significantly reduces system complexity while maintaining high-quality output. The model is particularly notable for its efficient processing pipeline and ability to handle both Chinese and English text.
