我无法使用带有语音识别的 urllib 进行搜索（我是初学者）

Question

我正在尝试在网站中搜索字符串，但无法搜索。

import speech_recognition as sr
import urllib
import urllib.request
import re

page = urllib.request.urlopen("https://en.wikipedia.org/wiki/Main_Page").read()

r = sr.Recognizer()
with sr.Microphone() as source:
    print("say something: ")
    audio = r.listen(source)

flag = False
try:

    print("you said: " + r.recognize_google(audio,))

    flag = True

except sr.UnknownValueError:
    print("error")
except sr.RequestError as e:
    print("error; {0}".format(e))


if flag:
    re.findall(r.recognize_google(audio), page)
    page.find(r.recognize_google(audio))

else:
    print("error")
    

错误是

return _compile(pattern, flags).findall(string) 类型错误：无法在类似字节的对象上使用字符串模式
