Discord BOT，guildMemberSpeaking事件不起作用

Question

我想让漫游器检测用户在讲话。在不一致的文档中，我看到我需要使用事件guildMemberSpeaking。这是代码：

const Discord = require('discord.js');
const client = new Discord.Client();


client.once('ready', () => {
    console.log('Talkover is online!');
})


// Joins the voice channel with every tekst
client.on('message', async message => {
    // Join the same voice channel of the author of the message
    if (message.member.voice.channel) {
        const connection = await message.member.voice.channel.join();

    }
});


client.on('guildMemberSpeaking', (member, speaking) => {

    if (speaking) {
        console.log('speaking');
    } else {
        console.log('notspeaking');
    }

});

由于某种原因，该消息有效，但公会成员却不讲话。我不知道我在做什么错。
