Fish Audio Releases Drama 3 35B3A Text-to-Speech Model
Fish Audio has released Drama 3 35B3A, a large Mixture of Experts text-to-speech model. Users can run the model locally using 4-bit quantization or test it directly via a Hugging Face Space demo. This release represents a significant advancement in open-source text-to-speech technology, offering high-quality localized voice synthesis capabilities for the machine learning community. It bridges the gap between massive enterprise-grade speech models and local deployment viability. Although Drama 3 35B3A is a chunky MoE model, it runs efficiently on specialized hardware like a DGX Spark. Furthermore, 4-bit quantization maintains output quality that is very close to the original unquantized model.
## BACKGROUND
A Mixture of Experts (MoE) is a neural network architecture where multiple sub-models ('experts') handle different parts of a task, governed by a router to improve efficiency and capacity. Model quantization reduces the precision of weights—such as converting 16-bit floats to 4-bit integers—drastically lowering memory and hardware requirements to run large models locally.
