Python的語音識別與聊天機器人

Question

我目前正在建設一個個人助理機器人是一個挑戰，而我在學校放假。我目前有麻煩了SpeechRecognition整合ChatterBot。當我在同一個文件都打電話，我沒有得到任何錯誤：

import speech_recognition as sr 
from chatterbot import ChatBot 

def setup(): 
    chatbot = ChatBot(
     'Ron Obvious', 
     trainer='chatterbot.trainers.ChatterBotCorpusTrainer' 
    ) 

    # Train based on the english corpus 
    chatbot.train("chatterbot.corpus.english") 
    while True: 
     get_response(chatbot) 

def get_response(chatbot): 
    # Get a response to an input statement 
    speech = return_audio() 
    print chatbot.get_response(speech) 

def return_audio(): 
    r = sr.Recognizer() 
    with sr.Microphone() as source: 
     audio = r.listen(source) 
    try: 
     speech = r.recognize_google(audio) 
     try: 
      speech = str(speech) 
      print speech 
      return speech 
     except TypeError: 
      print "Error! Could not convert speech to string!" 
    except sr.UnknownValueError: 
     print "Error! Could not process that audio." 
     return "Error!" 
    except sr.RequestError as e: 
     print "Error! No internet connection to Google Sound Recognizer." 
     return "Error!" 

setup() 

但是，如果我把兩個兩個不同的文件，我得到一個AttributeError。我得到的程序有它拋出一個異常崩潰左右，但這個例外意味着機器人從來沒有真正與用戶交互。

貝婁是兩個文件： 聽

import speech_recognition as sr 
from chatterbot import ChatBot 

import Messanger_Alert as MA 
import Weather 
import Email_Alert 
import Chat 
import Run 


def start(): 
    bot = Chat.start() 
    MA_client = MA.login() 
    print "Hello Luke!" 
    print "I am ready for your command! :D" 
    while True: 
     speech = str(return_audio()) 
     if not speech: 
      print "Error! Speech returned nonetype!" 
      continue 
     else: 
      try: 
       if any(word in speech for word in ("Jason", "jason")): #Old key words: "SysGen", "Sysgen", "System", "system" - will reimpliment if needed 
        if any(word in speech for word in ("Message", "message", "Messenger", "messenger", "Facebook", "facebook")): 
         if any(word in speech for word in ("Send", "send")): 
          MA.send_message(MA_client) #now getting an attribute error. 
          print "Ready for next command!" 
         elif any(word in speech for word in ("Search Friend", "search friend", "Seach friend", "search Friend", "friend", "Friend", "friends", "Friends")): 
          MA.friend_search(MA_client) 
          print "Ready for next command!" 
         elif any(word in speech for word in ("Check", "check")): 
          MA.check_message(MA_client) 
          print "Ready for next command!" 
        elif any(word in speech for word in ("Email", "email")): 
         if any(word in speech for word in ("Personal", "personal", "Home", "home")): 
          Email_Alert.login1() 
          print "Ready for next command!" 
         elif any(word in speech for word in ("School", "school", "Dorm", "dorm", "UCSD", "ucsd")): 
          Email_Alert.login2() 
          print "Ready for next command!" 
        elif any(word in speech for word in ("Weather", "weather", "Forecast", "forecast")): 
         Weather.decide() 
        elif any(word in speech for word in ("Goodnight", "goodnight", "Bye", "bye", "Goodbye", "goodbye")): 
         print "Goodnight Luke!" 
         exit() 
        else: 
         Chat.talk(bot, speech) 
       elif speech == "Error!": 
        return_audio() 
       else: 
        Chat.talk(bot, speech) 
      except sr.UnknownValueError: 
       print "Error! Could not process that audio." 
      except sr.RequestError as e: 
       print "Error! No internet connection to Google Sound Recognizer." 


def return_audio(): 
    r = sr.Recognizer() 
    with sr.Microphone() as source: 
     audio = r.listen(source) 
    try: 
     speech = r.recognize_google(audio) 
     try: 
      speech = str(speech) 
      print speech 
      return speech 
     except TypeError: 
      print "Error! Could not convert speech to string!" 
    except sr.UnknownValueError: 
     print "Error! Could not process that audio." 
     return "Error!" 
    except sr.RequestError as e: 
     print "Error! No internet connection to Google Sound Recognizer." 
     return "Error!" 

聊天：

from chatterbot import ChatBot 
from chatterbot.trainers import ListTrainer 
import os.path 

import Listen 

def start(): 
    file_list = ["Jason_logs.txt", "Sample1.txt"] 
    chatbot = ChatBot('Jason', trainer='chatterbot.trainers.ChatterBotCorpusTrainer') 
    for path in file_list: 
     if os.path.exists(path) == "True": 
      train_from_text(chatbot, path) 
    train_bot(chatbot) 

def train_from_text(chatbot, path): 
    conversation = [] 
    with open(path, 'r') as f: 
     while True: 
      line1 = f.readline() 
      line2 = f.readline() 
      if not line2: 
       break 
      else: 
       conversation.append(line1) 
       conversation.append(line2) 
    chatbot.set_trainer(ListTrainer) 
    chatbot.train(conversation) 

def train_bot(chatbot): 
    # Train based on the english corpus 
    chatbot.train("chatterbot.corpus.english") 
    # Train based on english greetings corpus 
    chatbot.train("chatterbot.corpus.english.greetings") 
    # Train based on the english conversations corpus 
    chatbot.train("chatterbot.corpus.english.conversations") 

def talk(chatbot, entry): 
    try: 
     response = chatbot.get_response(str(entry)) 
     print response 
     with open("Jason_logs.txt", "a") as f: 
      f.write(entry) 
      f.write(response) 
    except TypeError: 
     print "Error! Could not convert speech to string!" 
    except AttributeError: 
     print "Error! Speech not accepted by Jason's Chatterbot libraries." 

我不能完全肯定這是爲什麼，因爲他們都工作，如果他們是在同一個文件（第一大塊代碼）。但是，出於組織目的，如果可能的話，我寧願保持兩個文件分開。

感謝您的任何想法和解決方案您可能能夠給！

Answer 1

Chat.start()不返回chatbot，所以隱式返回的值是None。嘗試添加return chatbot到start()結束。你也可以考慮使自己的聊天機器人包裝類，而不是使用一個模塊並通過周圍聊天機器人實例。
