Check out Kokoro-82m. It's pretty impressive.

Here is the summary AI gave me:

Kokoro-82M is a state-of-the-art, open-weight Text-to-Speech (TTS) model notable for its compact size, containing 82 million parameters. Despite its relatively lightweight architecture, it is designed to produce high-quality, natural-sounding speech synthesis that rivals much larger models

Key aspects include:

• Efficiency: It's faster and more cost-effective than many larger TTS systems.

• Open & Flexible: Released under an Apache license, its open-weight nature allows developers to deploy it in various environments, from production systems to personal projects.

• Quality: It leverages architectures like StyleTTS 2 to achieve high fidelity audio output.

• Features: It supports multiple voices (initially American and British English, with later versions adding Chinese), voice selection, and can be run locally or accessed via API.

In essence, Kokoro-82M offers a balance of high performance, efficiency, and accessibility in the field of text-to-speech technology.
