对着电脑吼一声,自动打开谷歌网站或者自动打开命令行终端--使用google speech 语音识别程序操作电脑

1)更新源文件:@ubuntu:~$ sudo vim /etc/apt/sources.list

                deb http://cn.archive.ubuntu.com/ubuntu precise main restricted universe


2)更新源文件后,要 update:sudo aptitude update


3)我自己数据库有问题,重新安装mysql数据库:

                                    @ubuntu:~$ aptitude search mysql-server

                                    sudo aptitude reinstall mysql-server

                                  @ubuntu:~$ aptitude install mysql-server

                                  @ubuntu:~$ aptitude purge mysql-server


4)安装相关的包以及依赖环境:

sudo easy_install wave

~/pyvoice$ sudo aptitude install flac      此工具将 wav 转换成 flac

~/pyvoice$ sudo aptitude install python-alsaaudio 


5)思路:

输入--处理--输出

1:获取电脑录音-->WAV文件
    python record wav

2:录音文件-->文本
    STT: Speech to Text

    STT API Google API
    TTS: Text to Speech


3:文本-->电脑命令



6)代码:

jiangge@ubuntu:~/pycode/pyvoice$ tree
.
├── 1.flac
├── 1.txt
├── 1.wav
├── recordtest.py
├── runcmd.py
└── stt_google.py

采样的库:recordtest.py
SpeechToText:stt_google.py
runcmd.py
1.txt



采样的库:recordtest.py

#!/usr/bin/env python

## recordtest.py
##
## This is an example of a simple sound capture script.
##
## The script opens an ALSA pcm forsound capture. Set
## various attributes of the capture, and reads in a loop,
## writing the data to standard out.
##
## To test it out do the following:
## python recordtest.py out.raw # talk to the microphone
## aplay -r 8000 -f S16_LE -c 1 out.raw


# Footnote: I'd normally use print instead of sys.std(out|err).write,
# but we're in the middle of the conversion between python 2 and 3
# and this code runs on both versions without conversion

import sys
import time

import alsaaudio
import wave

def usage():
    sys.stderr.write('usage: recordtest.py [-c <card>] <file>\n')
    sys.exit(2)

    card = 'default'

    opts, args = getopt.getopt(sys.argv[1:], 'c:')
    for o, a in opts:
        if o == '-c':
            card = a

    if not args:
        usage()

    f = wave.open(args[0], 'wb')
    f.setnchannels(1)
    f.setsampwidth(2)
    f.setframerate(8000)

    # Open the device in nonblocking capture mode. The last argument could
    # just as well have been zero for blocking mode. Then we could have
    # left out the sleep call in the bottom of the loop
    inp = alsaaudio.PCM(alsaaudio.PCM_CAPTURE, alsaaudio.PCM_NONBLOCK, card)

    # Set attributes: Mono, 44100 Hz, 16 bit little endian samples
    inp.setchannels(1)
    inp.setrate(8000)
    inp.setformat(alsaaudio.PCM_FORMAT_S16_LE)

    # The period size controls the internal number of frames per period.
    # The significance of this parameter is documented in the ALSA api.
    # For our purposes, it is suficcient to know that reads from the device
    # will return this many frames. Each frame being 2 bytes long.
    # This means that the reads below will return either 320 bytes of data
    # or 0 bytes of data. The latter is possible because we are in nonblocking
    # mode.
    inp.setperiodsize(160)

    loops = 2000000
    while loops > 0:
        loops -= 1
        # Read data from device
        l, data = inp.read()
      
        if l:
            f.writeframes(data)
            time.sleep(.001)

run_browser(cmds)
run_jeap(cmds)
run_term(cmds)
run_gedit(cmds)

7)运行:

jiangge@ubuntu:~/pycode/pyvoice$ python recordtest.py 1.wav;python stt_google.py ;python runcmd.py

然后对着电脑喊"新浪"

会看到命令行变化:

新浪网
新浪吗
新浪


如果正常的话,你就会在浏览器上看到已经打开新浪网首页了.不正常的情况...嗯,Fuck GFW
