Git主页：git clone https://github.com/kaldi-asr/kaldi.git kaldi --origin upstream 下载后，所需操作为：
cd kaldi/tools/; make; cd ../src; ./configure; make
第一步：cd kaldi/tools/
第二步：make，显示：zhaodeng@ubuntu:~/kaldi/tools$ makeextras/check_dependencies.shextras/check_dependencies.sh: zlib is not installed.extras/check_dependencies.sh: automake is not installed.extras/check_dependencies.sh: autoconf is not installed.extras/check_dependencies.sh: sox is not installed.extras/check_dependencies.sh: gfortran is not installed.extras/check_dependencies.sh: neither libtoolize nor glibtoolize is installedextras/check_dependencies.sh: subversion is not installedextras/check_dependencies.sh: Intel MKL is not installed.

Git: 下载后，添加到matlab路径中即可。1）Pull the GitHub repository or unzip the zip archive into any suitable folder (assumed below to be C:\sap-voicebox)
2）Start MATLAB, click “Set Path”, click “Add Folder …”, navigate to C:\sap-voicebox\voicebox, click “Select Folder” then click “Save”. 3）[Optional] The routine v_voicebox.m contains various installation-dependent parameters which may need to be altered before using the toolbox. In particular it contains a number of default directory paths indicating where temporary files should be created, where speech data normally resides, etc. You can override the defaults by editing v_voicebox.m directly or, more conveniently, by setting an environment variable VOICEBOX to the path of an initializing m-file. See the comments in v_ voicebox.m for a fuller description. 4）[Optional] You may find it convenient to install the non-unicode IPA phonetic symbol fonts developed by SIL which are in the C:\sap-voicebox\external\silipa93 folder. 5）[Optional] The folder C:\sap-voicebox\external\shorten contains the source code and compiled executable for the SHORTEN program written by Tony Robinson and SoftSound Limited www.softsound.com. This is needed for reading compressed SPHERE format files. You may wish to move it elsewhere but, if so, you will need to edit v_voicebox.m to give its location.在matlab中输入：
