我不能使用python discord模块使bot加入不和谐的语音通道

import discord
from discord.ext import commands
import speech_recognition as sr
description = 'Tutorial Bot'
bot_prefix = '?'
client = commands.Bot(description=description, command_prefix=bot_prefix)
@client.event
async def on_message(message):
    if message.content.startswith("Alice"):
        msg = await client.send_message(message.channel, 'Hello')
@client.event
async def on_voice_state_update():
    with sr.Microphone() as source:
        r = sr.Recognizer()
        audio = r.listen(source)
        command = r.recognize_google(audio)
        msg = await client.send_message(message.channel, comman)
async def joinVoiceChannel():
    channel = client.get_channel("FILL")
    await client.join_voice_channel(channel)
@client.event
async def on_ready():
    print("Logged in")
    print("Name : {}".format(client.user.name))
    print("ID : {}".format(client.user.id))
    print(discord.__version__)
    await joinVoiceChannel()
client.run("FILL")

我正在尝试创建一个可以加入呼叫的机器人，在激活麦克风时听到音频并使用语音识别模块以字符串形式输出消息 . 但是我在机器人加入呼叫时遇到了困难，而且我还没有找到一种方法从discord中获取音频输入 .
