Narrator

The mod is built mainly for players with visual impairments. It reads aloud text from many game elements that ordinary screen readers often skip, including item and block tooltips, inventories, creative tabs, the Book and Quill screen, boss bars, experience level, potion effects, buttons and the F3 debug screen. Narrator speaks the element under the cursor as it is hovered, which removes the need to press a key again and again.

A separate text-to-speech engine produces the spoken output, and it can load a range of voice models. Only two model files are needed for each voice, one ending in .onnx and one in .onnx.json, and both must share the same base name with different extensions. Multi-speaker models meant for Minecraft are supported, and a single-speaker model also works, though with lower quality. Changing the voice model takes effect immediately, and no restart is required.

Chat is read one message at a time, since a clicked line is the only way to separate lines in a multi-line message. When messages arrive quickly, the voiceover can play several at once. Speech for each line of a multi-line message is planned for a future version.
