How to Install Tortoise TTS on Ubuntu 24.04

Tortoise TTS is a high-quality text-to-speech system built with a focus on natural-sounding speech with rich prosody, emotional expression, and voice variety. Unlike many TTS engines that sound robotic, Tortoise uses a diffusion-based approach to generate speech that captures nuance, rhythm, and intonation. It supports multiple preset voices out of the box and allows voice cloning from short audio samples. The system is designed for quality over speed — it's slower than real-time but produces some of the most natural-sounding open-source TTS available. Key features include: multi-voice support with 10+ built-in presets, voice cloning from 10+ seconds of audio, emotional range control, strong autoregressive decoder with CLIP latents, and Python API for integration into larger applications.
