对于简单的对话需要普通话比较标准,当然可以设置成四川话,不过对于名字也可能出错,因为近音词太多了。

2、实现过程
2.1、首先获取语音

通俗点讲就是你说话生成语音文件

def save_wave_file(filepath, data):
  wf = wave.open(filepath, 'wb')
  wf.setnchannels(channels)
  wf.setsampwidth(sampwidth)
  wf.setframerate(framerate)
  wf.writeframes(b''.join(data))
  wf.close()
  
def my_record():
  pa = PyAudio()
  #打开一个新的音频stream
  stream = pa.open(format=paInt16, channels=channels,
           rate=framerate, input=True, frames_per_buffer=num_samples)
  my_buf = [] #存放录音数据
 
  t = time.time()
  print('正在录音...')
  while time.time() < t + 4: # 设置录音时间(秒)
  	#循环read,每次read 2000frames
    string_audio_data = stream.read(num_samples)
    my_buf.append(string_audio_data)
  print('录音结束.')
  save_wave_file(FILEPATH, my_buf)
  stream.close()

必须要通过语音文件进行对话才行,所以首先转换成语音文件。

2.2、获取文件内容

就是语音文件转换成文字,这里调用了百度语音识别

def listen():
 # 读取录音文件
 with open(FILEPATH, 'rb') as fp:
   voices = fp.read()
 try:
   # 参数dev_pid:1536普通话(支持简单的英文识别)、1537普通话(纯中文识别)、1737英语、1637粤语、1837四川话、1936普通话远场
   result = client.asr(voices, 'wav', 16000, {'dev_pid': 1837, })
   # result = CLIENT.asr(get_file_content(path), 'wav', 16000, {'lan': 'zh', })
   # print(result)
   # print(result['result'][0])
   # print(result)
   result_text = result["result"][0]
   print("you said: " + result_text)
   return result_text
 except KeyError:
   print("faild")
2.3、通过接口图灵机器人对话

注册图灵机器人之后会有一个语音接口,这里是用爬虫对他对话的

 
class TuringChatMode(object):
    #初始化API请求地址
    def __init__(self):
        # API接口地址
        self.turing_url = 'http://www.tuling123.com/openapi/api?'

     #定义人机交互方法
    def botInteraction (self,text):
        url_data = dict(
            key = 'e7ea86036040426e8a9d123176bfe12f',
            info = text,
            userid = 'yjc',
        )
      
        self.request = Request(self.turing_url + urlencode(url_data))#设置并实例化Request

        try:
            w_data = urlopen(self.request)#发送请求
        except URLError:
            raise Exception("No internet connection available to transfer txt data")
            #断言了请求URL异常
        except:
            raise KeyError("Server wouldn't respond (invalid key or quota has been maxed out)")
            # 其他情况断言提示服务相应次数已经达到上限

        response_text = w_data.read().decode('utf-8')
        #print(response_text)

        json_result = json.loads(response_text)#将json格式进行解析

        return json_result['text']
3.4、获取图灵机器人的对话之后转成语音播报
            engine = pyttsx3.init()
            engine.say(botMsg)
            engine.runAndWait() 

我是同的win实现的,所以这个如果用到硬件上面的话可以看看怎么写代码
