PocketSphinx文档翻译： 构建可运行于安卓上的Pocketsphinx,Building Pocketsphinx On Android
（ ☯：这篇教程里面不是完全正确的 ，但是非常有参考价值。部分评论也有参考价值，于是也被翻译了。 ）
我知道，妳们等这个教程等了好久了，现在就为妳们献上。感谢Matthew Cooper写下了这篇文章。此教程中说明的步骤应当能够在任何的GNU/Linux 发行版上正常工作 ，例如Fedora。另外 ，此教程预期的安卓手机系统版本为2.2 及以上。较低版本的安卓系统中 ，其SD卡的路径有点不一样，明白这一点的话同样能够轻松地按照这个教程完成妳的任务 。
下载并编译pocketsphinx
从这个网址下载以下两个源代码包 http://cmusphinx.sourceforge.net/wiki/download/
sphinxbase-0.8
pocketsphinx-0.8
然后从以下仓库下载PocketSphinxDemo
PocketsphinxAndroidDemo – snapshot
将三个源代码包都解压到某个妳能够在日后找到的地方。有一点要特别注意 ，pocketsphinx和sphinxbase源代码包都要解压到同一个上级目录中，并且将解压出来的子目录重命名为“sphinxbase”和“pocketsphinx”，目录名中不要带版本号。
打开终端并执行：
sudo -i
然后输入妳的密码。这样妳就获得root权限了。
妳稍后将用到swig，所以现在就安装它吧。妳需要安装swig 1.3，目前我们还不支持新版本的swig，例如2.0 ：
apt-get install swig
或者
yum install swig
现在，在命令行切换（cd）到sphinxbase 目录中，运行以下命令 ：
./configure
make
make install
切换到pocketsphinx 目录中，执行：
./configure
make
make install
现在切换到PocketSphinxDemo/jni目录中
打开jni 目录中的Android.mk文件，然后修改SPHINX_PATH(第5行)的值，指向包含有pocketsphinx 和sphinxbase 的上级目录 。
在命令行中执行以下命令：
妳的ndk目录的路径 /ndk-build -B
当然，这里要把 妳的ndk目录的路径 替换成妳电脑上ndk目录的实际路径
Eclipse
现在打开Eclipse，导入PocketSphinxDemo这个项目。
手机
将妳的安卓手机用USB连接，然后在此目录下创建 edu.cmu.pocketsphinx子目录
/mnt/sdcard
妳可以在终端里完成这个操作：
adb shell
在上一步获取到的外壳（shell）中：
mkdir /mnt/sdcard/edu.cmu.pocketsphinx
现在切换进入手机上的edu.cmu.pocketsphinx 目录，并且创建以下的目录结构（☯：注意参考一下 pocketsphinx源代码里的目录关系）：
edu.cmu.pocketsphinx
|
----> hmm
| |
| ----> en_US
| |
| ----> hub4wsj_sc_8k
|
----> lm
|
-----> en_US
现在执行quit 以退出adb 外壳。
此时仍然在终端中操作，将电脑上的文件推送到手机上去。
切换到pocketsphinx/model/hmm/en_US/目录然后执行：
adb push ./hub4wsj_sc_8k /mnt/sdcard/edu.cmu.pocketsphinx/hmm/en_US/hub4wsj_sc_8k
切换到pocketsphinx/model/lm/目录然后执行：
adb push ./en_US /mnt/sdcard/edu.cmu.pocketsphinx/lm/en_US
现在打开以下目录中的RecognizerTask.java文件
/src/edu/cmu/pocketsphinx/demo
代码里声明的某些路径在2.2 版本的手机上无效。我们需要修改这些路径，使得它们正常工作。看看下面这段代码。
pocketsphinx.setLogfile("/mnt/sdcard/edu.cmu.pocketsphinx/pocketsphinx.log");
Config c = new Config();
/*
* 在2.2及更高版本的系统中，我们可以使用getExternalFilesDir()或类似的函数
*/
c.setString("-hmm", "/mnt/sdcard/edu.cmu.pocketsphinx/hmm/en_US/hub4wsj_sc_8k");
c.setString("-dict", "/mnt/sdcard/edu.cmu.pocketsphinx/lm/en_US/hub4.5000.dic");
c.setString("-lm", "/mnt/sdcard/edu.cmu.pocketsphinx/lm/en_US/hub4.5000.DMP");
c.setString("-rawlogdir", "/mnt/sdcard/edu.cmu.pocketsphinx"); //只用来储存录音文件
如果妳采用的是不同的模型，则妳需要使用不同的路径，例如对于满语（mandarin）模型就要这样
c.setString("-hmm", "/sdcard/Android/data/edu.cmu.pocketsphinx/hmm/zh/tdt_sc_8k");
c.setString("-dict", "/sdcard/Android/data/edu.cmu.pocketsphinx/lm/zh_TW/mandarin_notone.dic");
c.setString("-lm", "/sdcard/Android/data/edu.cmu.pocketsphinx/lm/zh_TW/gigatdt.5000.DMP");
好了，构建并运行这个项目吧。

啊，感谢这篇教程，它写得狠好，狠简单。当然，它需要读者对于安卓开发有基本的了解！
我遇到了一些问题，希望妳能帮助我！
我使用的是：
MacOS 10.6.7 (预装的SWIG版本是1.3.31)
NDK: android-ndk-r5b 2011年1月版
SDK 2.2 API8, 设备模拟器-5554之前一直狠顺利，直到我要使用 NDK 来编译原生代码时出现问题。
—
在命令行执行：
妳的ndk目录的路径/ndk-build -B
当然，将妳的ndk目录的路径 替换成妳的ndk 目录的真实路径
—–在做这一步时，我遇到了错误，它还特别长，所以我只复制开头和结尾的部分：

我试过在“PocketSphinxDemo/jni/”和“PocketSphinxDemo/”目录（按照http://developer.android.com/sdk/ndk/index.html的说明是可以这样做的）中都执行了"/ndk-build -B”命令。我记得上面那一堆错误信息是在第二个目录中执行时产生的，但是两个目录中产生的错误信息实际上是非常相似的。
这些信息足够找到原因了吗？
—————-
—————-在教程的后面部分，我成功地将项目导入了Eclipse，构建了它，并且在模拟器中运行。程序启动动了，但是，当我点击“Record”的时候，程序崩溃了。**我修改了“RecognizerTask.java”中的那些路径，直接访问了我的电脑上解压后的“/pocketsphinx/”目录中的“.dic、.DMP等等”文件，而不是将它们复制/推送到SD卡中去。
—————-
—————-
对于教程中所说的在SD卡上创建目录结构的部分，我认为，它们应当是与解压后的“/pocketsphinx/”目录中的结构类似，所以应当是以下这样的一个结构对吧？SDCard—>edu.cmu.pocketsphinx—-> hmm—-> en_US—-> hub4wsj_sc_8k
SDCard—>edu.cmu.pocketsphinx—-> lm—–> en_US再次感谢

Benmael:

collect2: ld returned 1 exit status它在链接到sphinxbase的时候失败了。妳需要检查确认：正确地指定了sphinxbase 的路径；sphinxbase 库存在并且已经编译过了。
> Regarding the part of creating the folder structure in the SDCard, I think it has to be something similar to the unzipped “/pocketsphinx/” dir structure, so the diagram should be something like this maybe?
妳怎么安排这个目录结构并不重要。重要的是，妳要在源代码里指定正确的位置。

啊。当我先用ndk-build 来编译一个示例项目时，成功地编译了。但是，当我编译pocketsphinx_jni时就遇到了错误
我不知道原因。

遇到未定义的引用（undefined reference）错误时，可以尝试这样解决：
编辑Android.mk文件。修改第162 行：LOCAL_STATIC_LIBRARIES := sphinxutil sphinxfe sphinxfeat sphinxlm pocketsphinx
改成：LOCAL_STATIC_LIBRARIES := pocketsphinx sphinxlm sphinxfeat sphinxfe sphinxutil -
我解决了自己之前遇到的问题了。它与JNI毫无关系。
我误解了教程中所画的那个目录树的结构了：这样写也许会更好：
cd /mnt/sdcard
mkdir edu.cmu.pocketsphinx
cd edu.cmu.pocketsphinx
mkdir hmm
mkdir hmm/en_US
mkdir hmm/en_US/hub4wsj_sc_8k
mkdir lm
mkdir lm/en_US@ Stewart Boling
妳好像遇到了类似的问题，因为妳的logcat 记录跟我的完全一样。
检查一下/mnt/sdcard/edu.cmu.pocketsphinx/pocketsphinx.log中的错误记录。晚安！
-
最近几天都在调试这个问题。
我看到的现象是，程序启动了，但是马上就退出了。eclipse中最后一条调试信息是“JNI_onLoad”
让我们把话说远点。通用来讲，NDK的错误处理非常差，所以要想弄清楚是哪里的问题会是狠难的，它会直接崩溃掉（然后就没戏了）。由于pocketsphinx不大可能在这个层面上出问题，所以，应当是别的什么原因。
问题在于这段话：
“代码里声明的某些路径在2.2 版本的手机上无效。我们需要修改这些路径，使得它们正常工作。看看下面这段代码。
pocketsphinx.setLogfile(”/mnt/sdcard/edu.cmu.pocketsphinx/pocketsphinx.log”);
Config c = new Config();
/*
* 在2.2及更高版本的系统中，我们可以使用getExternalFilesDir()或类似的函数
*/
c.setString(”-hmm”, “/mnt/sdcard/edu.cmu.pocketsphinx/hmm/en_US/hub4wsj_sc_8k”);
c.setString(”-dict”, “/mnt/sdcard/edu.cmu.pocketsphinx/lm/en_US/hub4.5000.dic”);
c.setString(”-lm”, “/mnt/sdcard/edu.cmu.pocketsphinx/lm/en_US/hub4.5000.DMP”);
c.setString(”-rawlogdir”, “/mnt/sdcard/edu.cmu.pocketsphinx”); // Only use it to store the audio”
应该改成，对于2.2及以上版本的系统，将以下代码中的路径改成……
理想情况下，这个示例程序应当重写，将这些文件直接从资源（res）目录里提取出来，这样就不需要手动将它们推送到手机上了。这将会一帮不熟悉安卓的人带来狠大的方便。
