python语音转换文本

安装PocketSphinx 开源的api 用于语音转换文本
pip install PocketSphinx
pip install SpeechRecognition
如果安装PocketSphinx 报错：
Complete output (6 lines):
running bdist_wheel

building ‘sphinxbase._sphinxbase’ extension
swigging deps/sphinxbase/swig/sphinxbase.i to deps/sphinxbase/swig/sphinxbase_wrap.c

需要安装下载swig
下载：https://sourceforge.net/projects/swig/files/swigwin/swigwin-4.0.1/swigwin-4.0.1.zip/download?use_mirror=jaist
下载后解压缩在C盘，配置环境变量，用户环境变量中新增C:\swigwin-4.0.1
保存后 cmd 输入 swig -version 查看安装成功

重开anaconda 再安装 pip install PocketSphinx
如果出现下面错误
error: [WinError 3] 系统找不到指定的路径。: ‘D:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\PlatformSDK\lib’

需要安装twisted
去这个网站http://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted下载对应的文件
如果报错ERROR: Twisted-19.10.0-cp38-cp38-win32.whl is not a supported wheel on this platform.
需要查下 自己的版本
import pip._internal
print(pip._internal.pep425tags.get_supported())
如果不行使用
import pip
print(pip.pep425tags.get_supported())

根据这些信息选择下载

下载后放入C盘
在anaconda prompt中 路径指向文件保存路径然后 c:>pip install Twisted-19.10.0-cp37-cp37m-win_amd64.whl
安装成功后继续安装pip install PocketSphinx
