本文实例为大家分享了基于树莓派的语音对话机器人，供大家参考，具体内容如下

第一部分代码

arecord -D "plughw:1" -f S16_LE -r 16000 -d 3 /home/pi/Desktop/voice.wav

第二部分代码

# coding: utf-8import sys import json import urllib2 import base64 import requestsreload(sys) sys.setdefaultencoding(“utf-8”)def get_access_token(): url = “https://openapi.baidu.com/oauth/2.0/token” body = { “grant_type”:”client_credentials”, “client_id” :”此处填写自己的client_id”, “client_secret”:”此处填写自己的client_secret”, }r = requests.post(url,data=body,verify=True)respond = json.loads(r.text)return respond["access_token"]def yuyinshibie_api(audio_data,token): speech_data = base64.b64encode(audio_data).decode(“utf-8”) speech_length = len(audio_data) post_data = { “format” : “wav”, “rate” : 16000, “channel” : 1, “cuid” : “B8-27-EB-BA-24-14”, “token” : token, “speech” : speech_data, “len” : speech_length }url = "http://vop.baidu.com/server_api"json_data = json.dumps(post_data).encode("utf-8")json_length = len(json_data)#print(json_data) req = urllib2.Request(url, data=json_data)req.add_header("Content-Type", "application/json")req.add_header("Content-Length", json_length) #print("asr start request\n")resp = urllib2.urlopen(req)#print("asr finish request\n")resp = resp.read()resp_data = json.loads(resp.decode("utf-8"))if resp_data["err_no"] == 0: return resp_data["result"]else: print(resp_data) return Nonedef asr_main(filename,tok): try: f = open(filename, “rb”) audio_data = f.read() f.close() resp = yuyinshibie_api(audio_data,tok) return resp[0] except Exception,e: print “e:”,e return “识别失败”.encode(“utf-8”)

第三部分代码

# coding: utf-8 import requestsimport jsonimport sysreload(sys)sys.setdefaultencoding("utf-8") def Tuling(words): Tuling_API_KEY = "此处填写自己的Turling KEY" body = {"key":Tuling_API_KEY,"info":words.encode("utf-8")} url = "http:///text2audio?tex=暂停结束&lan=zh&cuid=B8-27-EB-BA-24-14&ctp=1&tok="+tok+"&per=3" os.system('mpg123 "%s"'%url) continue else: tex = Turling.Tuling(info) url = yuyinhecheng.yuyinhecheng_api(tok,tex) os.system('mpg123 "%s"'%url) time.sleep(0.5)
