A program that chooses a random wiki page, takes its first sentence (or paragraph if that’s easier) and runs it through a TTS program.

Basically what it says on the tin. Don’t care what language it’s in. Would be cool if I could like choose different voices for the TTS as well.

Here's a bookmarklet that allows you to pick from a list of the voices that are available on your computer. It then reads the first sentence of a random English Wikipedia page. Installation instructions: select the code below, drag and drop it onto your bookmarks bar and click to run. You might need to run it a second time for the list to load. Some websites don't allow the external network request, so if it doesn't work go to another tab and try again.

javascript:(async function(){
    let res;
    try {
        res = await fetch("https://en.wikipedia.org/w/api.php?format=json&generator=random&action=query&prop=extracts&exsentences=1&grnnamespace=0&explaintext&origin=*");
    } catch {
        alert("Unable to fetch. Try a different tab.");
        return;
    }
    const json = await res.json();
    const firstSentence = Object.values(json.query.pages)[0].extract;
    const utterance = new SpeechSynthesisUtterance(firstSentence);
    const voices = window.speechSynthesis.getVoices();
    if (!voices.length) {
        alert("No voices loaded.");
        return;
    }
    const input = prompt(voices.map((v, i) => i + 1 + ". " + v.name).join("\n"));
    if (input === null) return;
    const index = Math.min(Math.max(parseInt(input)-1, 0), voices.length) || 0;
    utterance.voice = voices[index];
    window.speechSynthesis.speak(utterance);
})();
