环境：mac 10.12


安装指导文档：http://cmusphinx.sourceforge.net/wiki/tutorialpocketsphinx
1 安装brew --mac下安装软件的好工具
按该网站首页的提示安装：http://brew.sh
2 按指导文档下载最新的pocketsphinx安装相关的包
http://cmusphinx.sourceforge.net/wiki/download
sphinxbase-5prealpha
pocketsphinx-5prealpha
sphinxtrain-5prealpha
sphinx4-5prealpha


3 进入 sphinxbase目录，运行./autogen.sh
发现运行失败，缺少autoconf等，这个时候就用第一步中brew安装：brew install autoconf
反应有点慢，耐心等待


4 运行autogen.sh后，继续按指导文档运行./configure
发现配置失败，找不到swig。继续brew install swig
之后，重新运行 ./configure ,配置成功
接着编译 make
然后安装 make install
然后配置环境变量 vi ~/.bash_profile 加入如下两行
--------------------------------------------------
export LD_LIBRARY_PATH=/usr/local/lib
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
--------------------------------------------------


5 进入pocketsphinx目录，重复3-4步


6 测试是否安装成功：重开一个命令窗口，敲入pocketsphinx_continuous -inmic yes,然后对着麦克风说话，会打出如下信息（最后一个是识别的信息，说实话识别的并不准确，也许是笔者发音不准）：
