Kokoro TTS: A Practical Text-to-Speech Model

What is Kokoro TTS?

Simply put, Kokoro-FastAPI is a Dockerized FastAPI wrapper based on the Kokoro-82M text-to-speech model. It supports multiple languages (English, Japanese, Chinese), provides an OpenAI-compatible voice interface, and supports NVIDIA GPU acceleration or CPU inference.

In plain English: You feed it some text, and it can read it out loud using various voices, and it sounds quite natural.

How to Use

After installing the application, open the main page.

The most basic usage is converting text to an audio file:

Enter your content in the text box. Content exceeding 500 characters will be automatically paginated.

Select the language model.

This feature is quite interesting; it can blend multiple voices:

Select the speech speed and language, then click the Generate button.

For one page of data, it takes about 2 minutes. After generation, click play to listen to the result.

The download button in the lower right corner can be used to download the MP3 file.

Check the /v1/audio/voices endpoint to get a list of all available voices.

The English results are also good, and the voice quality feels more natural.

Summary

Kokoro is a pretty decent local TTS solution, especially suitable for: Content Creators: Who need to generate voice content in bulk. Privacy-Conscious Users: Who don't want to send their text to the cloud.

Most importantly, this thing is completely free and open-source, so you don't have to worry about running out of API credits or the service being discontinued.
