我不太了解語音頻道，但您可以使用VoiceChannel.members檢查成員計數并進行如下任務循環

async def check():

? ? # define the voice channel

? ? member_count = len(voice_channel.members)

? ? if member_count == 1:

? ? ? ? # leave the channel

? ? await asyncio.sleep(30)

client.loop.create_task(check())

可能有更好的答案，但這也可以解決您的問題。

GUILD_VC_TIMER = {}

# this event runs when user leave / join / defen / mute 

@bot.event

async def on_voice_state_update(member, before, after):

    # if event is triggered by the bot? return

    if member.id == bot.user.id:

        return

    # when before.channel != None that means user has left a channel

    if before.channel != None:

        voice = discord.utils.get(bot.voice_clients , channel__guild__id = before.channel.guild.id)

        # voice is voiceClient and if it's none? that means the bot is not in an y VC of the Guild that triggerd this event 

        if voice == None:

            return

        # if VC left by the user is not equal to the VC that bot is in? then return

        if voice.channel.id != before.channel.id:

            return

        # if VC has only 1 member (including the bot)

        if len(voice.channel.members) <= 1:

            GUILD_VC_TIMER[before.channel.guild.id] = 0

            while True:

                print("Time" , str(GUILD_VC_TIMER[before.channel.guild.id]) , "Total Members" , str(len(voice.channel.members)))

                await asyncio.sleep(1)

                GUILD_VC_TIMER[before.channel.guild.id] += 1

                # if vc has more than 1 member or bot is already disconnectd ? break

                if len(voice.channel.members) >= 2 or not voice.is_connected():

                    break

                # if bot has been alone in the VC for more than 60 seconds ? disconnect

                if GUILD_VC_TIMER[before.channel.guild.id] >= 60:

                    await voice.disconnect()

                    return
