Answer 1

I went ahead an included Nicholas Johnson's Github bot code here, but I made slight modifications.

1. He appears to be creating a lock; so I created a LockableClient that extends the Discord Client.
2. Never include an authorization token in the code

auth.json

{
  "token" : "your-token-here"
}

lockable-client.js

const { Client } = require('discord.js')

/**
 * A lockable client that can interact with the Discord API.
 * @extends {Client}
 */
class LockableClient extends Client {
  constructor(options) {
    super(options)
    this.locked = false
  }
  lock() {
    this.setLocked(true)
  }
  unlock() {
    this.setLocked(false)
  }
  setLocked(locked) {
    return this.locked = locked
  }
  isLocked {
    return this.locked
  }
}

module.exports = LockableClient;

index.js

const auth = require('./auth.json')
const { LockableClient } = require('./lockable-client.js')

const bot = new LockableClient()

bot.on('message', message => {
  if (!bot.isLocked() && message.content === 'Gotcha Bitch') {
    bot.lock()
    var voiceChannel = message.member.voiceChannel
    voiceChannel.join().then(connection => {
      const dispatcher = connection.playFile('./assets/audio/gab.mp3')
      dispatcher.on('end', end => voiceChannel.leave());
    }).catch(err => console.log(err))
    bot.unlock()
  }
})

bot.login(auth.token)
