Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

インストール

$ npm i openjtalk.js

使い方

一番シンプルな例

//openjtalk.jsをインポート
const openjtalk = require('openjtalk.js');
//talk関数で音声の生成と再生を実行
openjtalk.talk('こんにちは、世界!');

声をカスタマイズする場合

const openjtalk = require('openjtalk.js');

const text = 'こんにちは、これはOpenJTalkによって生成された音声です。';

//デフォルトで搭載されているHTSボイスファイルのパスを取得
const mei_normal = openjtalk.getSpeaker('mei_normal');

const option = {
    speaker: mei_normal, //ここにはHTSボイスファイルのパスを指定します
    formant: 0.55,
    pitch: 0,
    speed: 1,
    intonation: 1,
};

openjtalk.talk(text, option).catch(console.error);

Readable 型で受け取る

Discord ボットで音声読み上げをしたい時などに利用できます

const openjtalk = require('openjtalk.js');
const fs = require('fs');
const path = require('path');
const { execFile } = require('child_process');

//ストリームの取得
const audioStream = openjtalk.stream('こんにちは、世界!');

//音声ファイルの生成
const wavPath = path.join(__dirname, './test.wav');
const outFile = fs.createWriteStream(wavPath);
audioStream.pipe(outFile);

//音声ファイルの生成が終了したら実行
audioStream.on('close', () => {
    switch (process.platform) {
        case 'darwin':
            playAndRefresh('afplay', wavPath);
            break;
        case 'linux':
            playAndRefresh('aplay', wavPath);
            break;
        default:
            console.error('Playback on this OS is not supported.');
            break;
    }
});

function playAndRefresh(com, path) {
    execFile(com, [path], () => {
        fs.unlinkSync(path);
    });
}

v2 から v3 への主な変更点

インストール時に open_jtalk をビルドしていましたが、リポジトリーを移してプリビルドしたものを利用するように変更しました。一部の環境(特に Ubuntu 24 系 以外の Linux ディストリビューション)では、このバイナリーが動かない可能性があります。
