如何在python2.7上结合语音识别和pyttsx

pip install SpeechRecognition
pip install pyttsx

import speech_recognition as sr
import pyttsx

r = sr.Recognizer()

with sr.Microphone() as source:
    print("请开始说话：")
    audio = r.listen(source)

try:
    text = r.recognize_google(audio, language='zh-CN')  # 使用Google语音识别API进行识别
    print("识别结果：" + text)
except sr.UnknownValueError:
    print("无法识别音频")
except sr.RequestError as e:
    print("无法连接到Google Speech Recognition服务：" + str(e))

engine = pyttsx.init()
engine.say(text)
engine.runAndWait()

import speech_recognition as sr
import pyttsx

# 创建语音识别器对象
r = sr.Recognizer()

# 使用麦克风录制音频并进行语音识别
with sr.Microphone() as source:
    print("请开始说话：")
    audio = r.listen(source)

try:
    text = r.recognize_google(audio, language='zh-CN')  # 使用Google语音识别API进行识别
    print("识别结果：" + text)
except sr.UnknownValueError:
    print("无法识别音频")
except sr.RequestError as e:
    print("无法连接到Google Speech Recognition服务：" + str(e))

# 使用pyttsx将文本转换为语音
engine = pyttsx.init()
engine.say(text)
engine.runAndWait()
