帮我用speech写一个文本转音频的代码

Sure, 我可以帮你用Python的Text to Speech库(SpeechSynthesis)实现文本转语音的功能。下面是代码示例：

import speech_recognition as sr
from gtts import gTTS
from playsound import playsound
import os

def text_to_speech(text):
    # 将指定文本转换为语音
    tts = gTTS(text=text, lang='en')
    # 将转换好的音频文件保存为mp3格式
    tts.save('output.mp3')
    # 播放音频文件
    playsound('output.mp3')
    # 删除音频文件
    os.remove('output.mp3')

# 使用语音识别库SR获取语音
def speech_to_text():
    r = sr.Recognizer()
    with sr.Microphone() as source:
        print("Say something!")
        audio = r.listen(source)
    try:
        # 调用Google语音识别API将语音转换为文本
        text = r.recognize_google(audio, language='en')
        print("Google Speech Recognition thinks you said " + text)
        # 将语音转换为文本并播放语音
        text_to_speech(text)
    except sr.UnknownValueError:
        print("Google Speech Recognition could not understand audio")
    except sr.RequestError as e:
        print("Could not request results from Google Speech Recognition service; {0}".format(e))

if __name__ == '__main__':
    speech_to_text()

使用方法：运行程序后，跟随终端指示，通过麦克风录入指定文本，程序将文本转换为语音并播放。
