DragonLineageAI/Vi-SparkTTS-0.5B

Spark TTS Vietnamese

Spark-TTS is an advanced text-to-speech system that uses the power of large language models (LLM) for highly accurate and natural-sounding voice synthesis. It is designed to be efficient, flexible, and powerful for both research and production use. This model is trained from viVoice vietnamese dataset

Usage

First, install the required packages:

pip install --upgrade transformers accelerate

Text-to-Speech

We have customized the code so you can inference using the huggingface transformer library without installing anything else.
