树莓派小爱同学、天猫精灵、智能音箱、百度语音极速版、百度语音标准版、语音识别、语音合成终极方案

第一句话，python2版本的代码，python3你改改就完事了

流程图如下：

全套教程下载地址点击下载

首先需要调用这个方法安装百度的语音识别

https://ai.baidu.com/ai-doc/SPEECH/Bk4o0bmt3

安装使用Python SDK有如下方式：

如果已安装pip，执行pip install baidu-aip即可。
如果已安装setuptools，执行python setup.py install即可。
然后下面的按我的来，然后就可以了

需要更改的地方是最上面的那一排排路径，还有就是需要自己在百度注册appId， apiKey ， secretKey，如下图所示：

注册地址，我好早之前注册的，所以注册我就细说不了

https://console.bce.baidu.com/ai/?fromai=1#/ai/speech/overview/index

这个下面是百度官方的tts语音合成

https://github.com/Baidu-AIP/speech-demo/tree/master/rest-api-tts/python

这个是我的语音合成，也是老版本百度的语音合成，这个简洁干练，没啥区别的，只是没有获取token这一部，但是好像没啥影响，不过据说token只有一个月的有效期，过了要继续获取，最下面代码中是实时获取的，不用担心，我的这个简短精悍的好像不需要token，哪里失效一说呢

# 发音人选择, 基础音库：0为度小美，1为度小宇，3为度逍遥，4为度丫丫，
# 精品音库：5为度小娇，103为度米朵，106为度博文，110为度小童，111为度小萌，默认为度小美
PER = 4
# 语速，取值0-15，默认为5中语速
SPD = 5
# 音调，取值0-15，默认为5中语调
PIT = 5
# 音量，取值0-9，默认为5中音量
VOL = 5
# 下载的文件格式, 3：mp3(default) 4： pcm-16k 5： pcm-8k 6. wav
AUE = 3robotVoicePath = '/home/pi/share/tts/dvic/voice.mp3'# 将本地文件进行语音合成，这个和下面那个tts都可以用，用这个方便快捷
def tts(word):result  = client.synthesis(word,'zh',1, {'vol':VOL,'per':PER,'spd':SPD,'pit':PIT})# 合成正确返回audio.mp3，错误则返回dictif not isinstance(result, dict):with open(robotVoicePath, 'wb') as f:f.write(result)f.close()print 'tts successful'#其中robotVoicePath 自己设定， 还有tts 后面那个括号中的word，例如： tts("你傻不傻")
#然后VOL、PER、SPD、PIT自己设定一下

下面是官方的语音识别代码demo，极速版本的代码这以下链接中注释了一部分，大家注意了

https://github.com/Baidu-AIP/speech-demo/blob/master/rest-api-asr/python/asr_raw.py

下面是我的百度语音识别普通版和极速版，需要更改一些路径，还有自己的appId， apiKey ， secretKey，需要改了才能跑，具体demo看最下面一个代码，那最全。

这里就是那个snowboy中python2的demo.py，然后我改进了一下，调用了上面的loopRecord.py

#_*_ coding:UTF-8 _*_
import snowboydecoder
import sys
import signal
import loopRecord
from light import Lightinterrupted = Falsedef signal_handler(signal, frame):global interruptedinterrupted = Truedef interrupt_callback():global interruptedreturn interrupted#  回调函数，语音识别在这里实现
def callbacks():global detector#led = Light(17)#led.blink()# 语音唤醒后，提示ding两声#snowboydecoder.play_audio_file()#snowboydecoder.play_audio_file()#  关闭snowboy功能detector.terminate()#  开启语音识别loopRecord.loopRecord()# 打开snowboy功能wake_up()    # wake_up —> monitor —> wake_up  递归调用# 热词唤醒
def wake_up():global detectormodel = 'snowboy.pmdl'  #  唤醒词为 可乐# capture SIGINT signal, e.g., Ctrl+Csignal.signal(signal.SIGINT, signal_handler)# 唤醒词检测函数，调整sensitivity参数可修改唤醒词检测的准确性detector = snowboydecoder.HotwordDetector(model, sensitivity=0.45)print('Listening... please say wake-up word:SnowBoy')# main loop# 回调函数 detected_callback=snowboydecoder.play_audio_file # 修改回调函数可实现我们想要的功能detector.start(detected_callback=callbacks,      # 自定义回调函数interrupt_check=interrupt_callback,sleep_time=0.03)# 释放资源detector.terminate()if __name__ == '__main__':# 打开snowboy功能wake_up()

这里是随机播放音乐的代码,可以循环播放的

#!/usr/bin/python
# -*- coding: UTF-8 -*-
import os
import random
import time
#播放音乐
def mplayerMusic(fileName):os.system('mplayer ' + '/home/pi/share/music/'+ '*' + fileName  + '*' + ' > /dev/null 2>&1 &')def closeMplayer():isRunStr = str(os.popen("ps -ef | grep mplayer | grep -v grep | awk '{print $1}' |sed -n '1p'").readline().strip())if isRunStr=='pi':os.system("ps -ef | grep mplayer | grep -v grep | awk '{print $2}' | xargs kill -9")def getMplayerIsRun():isRunStr = str(os.popen("ps -ef | grep mplayer | grep -v grep | awk '{print $1}' |sed -n '1p'").readline().strip())if isRunStr=='pi':return Trueelse:return Falsedef loop():closeMplayer()fileNameList = os.listdir('/home/pi/share/music')while True:time.sleep(2)if getMplayerIsRun()==False:fileName = fileNameList[random.randint(0,len(fileNameList) - 1)]mplayerMusic(fileName)loop()

目前我这个代码，基本已经实现了小爱同学的主要关键性功能：

1、语音唤醒，极速唤醒有木有，你再也不用循环录音，随机录音了，担心你录的声音只有一部分

2、语音识别，百度的语音识别功能没啥好说的，代码中有标准版本和极速版本，目前用的是极速版本，快就不用说了

3、语音合成，现在你可以小萝莉、御姐音、大叔音、暖男音、鬼哭狼嚎傻子音

4、录音时间，可长可短由你控制，再也不用担心说话来不及了，嘴巴甜的2秒说完，嘴巴慢的可以说7秒，你想说一辈子也行，改改代码就办到

码代码不易呀，大家有钱的支持个一块两块呀，也是个意思呀，哈哈哈，有钱的捧个钱场，没钱的点个赞评论一下，让我有点小感动也阔以呀！！！

实在不会弄的，私信我哦
