Question

大家好，我正在尝试开发一个虚拟助手，它可以帮助我完成一些项目，所以我试图获得最终项目的基础知识，但是我收到一个错误（UnboundLocalError：分配前引用的局部变量“命令”）和我试图将 return command 更改为 printf(command) 下，但它不让我说话，并且一条消息 NONE 和另一个错误（TypeError: argument of type 'NoneType' is not iterable）出现在终端。那么我怎样才能不停地工作呢？

代码如下：

import pyttsx3
import pywhatkit
import datetime

listener = sr.Recognizer()
engine = pyttsx3.init()

def talk(text):
    engine.say(text)
    engine.runAndWait()

def take_command():
    try:
        with sr.Microphone() as source:
            print('listening...')
            voice = listener.listen(source)
            command = listener.recognize_google(voice)
            command = command.lower()
            if 'skor' in command:
                command = command.replace ('skor', '')
                print(command)
    except:
        pass
    return command
def run_skor():
    command = take_command()
    print(command)
    if 'play on youtube' in command:
        song = command.replace ('play on youtube', '')
        talk('playing' + song)
        pywhatkit.playonyt(song)
    elif 'search on google' in command:
        sea = command.replace ('search on google', '')
        talk ('searching' + sea)
        pywhatkit.search(sea)
    elif 'tell me the time' in command:
        time = datetime.datetime.now().strftime('%H:%M')
        print(time)
        talk('Current time is' + time)
while True:
    run_skor()```

Answer 1

您需要进行的唯一更改是在 take_command() 函数中。这是我的版本：

def take_command():
    try:
        with sr.Microphone() as source:
            print('listening...')
            voice = listener.listen(source)
            command = listener.recognize_google(voice)
            command = command.lower()
            if 'skor' in command:
                command = command.replace ('skor', '')
                print(command)
    except sr.UnknownValueError:
        command = ""
    return command

基本上，您可以先更改 execpt 命令，更具体地说。 sr 有一个名为 UnknownValueError 的内置命令。我们可以使用它来更具体地了解except命令何时起作用。然后，在 except 中，将命令设置为 ""。这将停止错误，因为当命令返回时，它仍然是一个字符串，并且仍然有效。

Answer 2

def takeCommand():
    r = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        audio = r.listen(source)

        try:
        print("Recognizing...")
        command = r.recognize_google(audio, language='en-in')
        print(f"User said: {command}\n")

    except Exception as e:
        print("Say that again please...")
        return "None"

    return command.lower()
