How to get rid of this ffmpeg?

Question

I am currently working on a bot. Its function is to join voice channels and speak with tts .

This is my attempt so far:

try {
    const broadcast = client.voice.createBroadcast();
    var channelId = message.member.voice.channelID;
    var channel = client.channels.cache.get(channelId);
    channel.join().then(connection => {
        broadcast.play(discordTTS.getVoiceStream("Staline est né le : 18 Décembre 1878."));
        const dispatcher = connection.play(broadcast);
    });
    message.delete();
}
catch (e) {
    console.log(e);
}

This is the error I'm getting:

events.js: 292
throw er; // Unhandled 'error' event
          ^

    Error: spawn ffmpeg ENOENT

                    spawnargs: [

                        '-ac', '2',
                        'pipe:1'
                    ]
}

I really don't understand, I never asked for ffmpeg to be here

As far as I know /tts is inner Discord's function (not discord.js). Bot can't join and speak by tts. You can make something like this:

client.on('message', message => {
    message.channel.send(args, {
        tts: true
    });
});

Without joining voice channel!

Update!

I didn't mention that you are using "discord-tts". First of all you have to install all needed dependencies: @discordjs/opus and ffmpeg-static

Then try your code or this:

if (msg.content==="say test 123") {
    const broadcast = bot.voice.createBroadcast();

    if (msg.member.voice.channel) {
        const connection = await msg.member.voice.channel.join();

        broadcast.play(discordTTS.getVoiceStream("test 123"));

        const dispatcher = connection.play(broadcast);

    } else {
        await msg.reply('You need to join a voice channel first!');
    }
}
