AllTalk TTS is a Python-based extension for the Text Generation Web UI, offering advanced text-to-speech capabilities. It targets users who want to integrate high-quality, customizable speech synthesis into their workflows, particularly within conversational AI or content creation, by leveraging the Coqui TTS engine.

How It Works

AllTalk TTS is built upon the Coqui TTS engine, specifically supporting XTTSv2 models. It provides a user-friendly interface with features like model finetuning, support for custom local models, and efficient batch processing. Advanced options include DeepSpeed for performance acceleration and a low VRAM mode, making it accessible even on hardware with limited GPU memory.

Quick Start & Requirements

• Installation: Clone the repository into your Text Generation Web UI extensions folder (git clone https://github.com/erew123/alltalk_tts) or use the provided setup scripts (atsetup.bat / ./atsetup.sh) for standalone installations.
• Prerequisites: Python 3.9-3.11.x (tested with 3.11.x), Git. For DeepSpeed, an NVIDIA GPU is required. Windows users may need C++ build tools.
• Resources: Initial model download is ~1.8GB.
• Documentation: AllTalk TTS GitHub

Highlighted Details
