我正在尝试为我的项目创建一个简单的助手。我创建了一个mp3文件，并使用gtts模块将其保存。之后，我尝试播放该文件，但无法播放。我尝试了许多不同的模块。我尝试os.system（）播放mp3文件，但它给了我权限被拒绝的错误。 我在pycharm中使用anaconda环境来运行我的项目。我在anaconda环境中使用的python版本是3.6。我曾尝试pygame尝试使音频文件破损，但它也不起作用。
下面是我尝试的代码和我得到的错误。
import time
import speech_recognition as sr
from gtts import gTTS
from pydub import AudioSegment
from pydub.playback import play
def playMp3(filename):
mp3file = AudioSegment.from_mp3(filename)
play(mp3file)
def playWav(filename):
wavfile = AudioSegment.from_file(filename)
play(wavfile)
def speak(sentence):
tts = gTTS(text=sentence, lang='en')
filename = './new.wav'
tts.save(filename)
playMp3(filename)
def get_audio():
r = sr.Recognizer()
with sr.Microphone() as source:
r.adjust_for_ambient_noise(source)
print('say something')
audio = r.listen(source)
said = ''
try:
said = r.recognize_google(audio)
print(said)
except Exception as e:
print('Exception: ' + str(e))
return said
# text = get_audio()
# if 'hello' or 'hi' in text:
speak('hello, how are you?')
运行以上代码后，出现以下错误

我运行以下脚本来检查默认采样率，并得到以下结果：

之后，我运行以下命令来检查声卡
lspci -knn|grep -iA2 audio
并得到以下结果

我还调试了代码，并进入pyaudio.py文件。它在给出错误的行上有一个断点。但是，我真的不知道这是什么。也许我必须在pyaudio中手动更改采样率。由于默认采样率是44100，在pyaudio.py中，采样率是24000。
下面是self._stream = pa.open（** arguments）
的参数{'rate'：24000，'channels'：1，'format'：8，'input'：False，'output'：True，'input_device_index'：无，'output_device_index'：无，'frames_per_buffer'： 1024}
对于我的系统信息，我正在使用ubuntu 20.04，默认的python版本是3.8，但是在我的anaconda环境中，我正在使用python 3.6
我在终端中运行alsamixer命令，并获得了有关声卡的以下信息
0 HDA Intel HDMI
1 HDA Intel PCH
请帮助我摆脱这种情况。我被困在这里太久了，一直在寻找它，但似乎找不到解决方法。如果需要有关我的硬件或任何其他配置的更多信息，我可以提供。
