Python Gtts助手

Question

我已经使用这个网站上的教程为Python语言编写了一个简单的助手代码：https://randerson112358.medium.com/build-a-virtual-assistant-using-python-2b0f78e68b94。创建者的代码是错误的，我已经修复了一些缩进错误。不过，它还有其他一些错误，我想要修复这些错误。

错误，例如：

Traceback (most recent call last):
  File "C:\Users\Johann\Desktop\BIZ\Python\BoringAuto1.py", line 120, in <module>
    assistantResponse(response)
  File "C:\Users\Johann\Desktop\BIZ\Python\BoringAuto1.py", line 33, in assistantResponse
    myobj = gTTS(text=text, lang="en", slow=False)
  File "C:\Users\Johann\AppData\Local\Programs\Python\Python39\lib\site-packages\gtts\tts.py", line 126, in __init__
    assert text, 'No text to speak'
AssertionError: No text to speak

如果你能帮我一把，那就太棒了。代码如下：

import speech_recognition as sr
import os
import datetime
import warnings
import calendar
from gtts import gTTS
import random
import wikipedia

warnings.filterwarnings('ignore')

def recordAudio():
    r = sr.Recognizer()
    with sr.Microphone() as source:
        print("Say something!")
        audio = r.listen(source)

    data = ""
    try:
        data = r.recognize_google(audio)
        print("You said:  " + data)
    except sr.UnknownValueError:
        print("Google Speech Recognition could not understand")
    except sr.RequestError as e:
        print("Request error from Google Speech Recognition")
    return data



def assistantResponse(text):
    print(text)

    myobj = gTTS(text=text, lang="en", slow=False)

    myobj.save("assistant_response.mp3")

            else:
                meridiem = "a.m."
                hour = now.hour

            if now.minute < 10:
                    minute = "0"+str(now.minute)
            else:

    if ("who is" in text):
        person = getPerson(text)
        wiki = wikipedia.summary(person, sentences=2)
        response = response + "" + wiki

    assistantResponse(response)

提前感谢！

致以最好的问候，约翰

首先，在发言之前，请检查是否有要发言的文本：

if response != "":
  assistantResponse(response)

其次，您可以将“who is”函数包装在try except块中，以捕获“未找到”错误。

def getPerson(text):
  wordList = text.split()
  for i in range(0, len(wordList)):
    if i + 3 <= len(wordList) - 1 and wordList[i].lower() == 'who' and wordList[i + 1].lower() == 'is':
      return wordList[i + 2] + ' ' + wordList[i + 3]
  return ""
if 'who is' in text:
  person = getPerson(text)
  if person != "":
    wiki = wikipedia.summary(person, sentences=2)
    response += wiki
  else:
    response += "I could not find the person you were looking for"

这应该会捕获我在测试您的程序时遇到的所有错误。
