如果工作正常但 elif 抛出错误

Question

我正在编写 python 代码（已提供）；但是当我说 'open photos' 时一切正常并且它识别出我说的是 'open photos' 但抛出 except 语句而不是 'elif listen() == "open photos": output'。请帮助我。

import speech_recognition as sr
import pyttsx3
import time
friday = pyttsx3.init('sapi5')
r = sr.Recognizer()
mic = sr.Microphone()
friday.setProperty('rate', 150)
def listen():
     with mic as source:
         r.adjust_for_ambient_noise(source)
         audio = r.listen(source)
         try:
           text =  r.recognize_google(audio)
           print(text)
           return text
         except sr.UnknownValueError:
          friday.say("sorry sir , could't do that")
          friday.runAndWait()
print("started!")
while 1:
    if listen() == "hello Jarvis":
        friday.say("hello sir")
        friday.runAndWait()
    elif listen() == "open photos":
            friday.say("opening")
            friday.runAndWait()

Answer 1

我认为你需要的是更好的关注。 listen 将消耗输入；第二次调用它会迫使你重复这个短语。相反，第一次注意。 :-)

heard = listen()
if heard == "hello Jarvis":
    friday.say("hello sir")
    friday.runAndWait()
elif heard == "open photos":
    friday.say("opening")
    friday.runAndWait()

请注意，如果缩进一致，您的代码将更易于阅读：处于同一处理级别的代码，即使在独立块之间，也应缩进到同一级别。

if is working properly but elif throws an error
