kaldi集成到应用hap
本库是在RK3568开发板上基于OpenHarmony3.2 Release版本的镜像验证的，如果是从未使用过RK3568，可以先查看润和RK3568开发板标准系统快速上手。

三方库目录结构

在lycium目录下编译三方库 编译环境的搭建参考准备三方库构建环境
cd lycium ./build.sh kaldi -
三方库头文件及生成的库 在lycium目录下会生成usr目录，该目录下存在已编译完成的32位和64位三方库
kaldi/armeabi-v7a kaldi/arm64-v8a
应用中使用三方库
-
在IDE的cpp目录下新增thirdparty目录，将编译生成的库头文件拷贝到该目录下, 如下图所示
-
在最外层（cpp目录下）CMakeLists.txt中添加如下语句
#将三方库加入工程中 target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-base.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-cblasext.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-chain.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-cudamatrix.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-decoder.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-feat.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-fstext.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-gmm.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-hmm.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-ivector.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-kws.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-lat.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-lm.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-matrix.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-nnet3.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-online2.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-rnnlm.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-transform.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-tree.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/kaldi-util.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libblas.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libf2c.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/liblapack.a ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libopenblas.a) #将三方库的头文件加入工程中 target_include_directories(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/OpenBLAS/${OHOS_ARCH}/include ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/kaldi/${OHOS_ARCH}/include ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/clapack/${OHOS_ARCH}/include)
测试三方库
三方库的测试使用原库自带的测试用例来做测试，准备三方库测试环境
- 进入到构建目录,执行如下命令（kaldi-kaldi10-arm64-v8a-build为构建64位的目录，kaldi-kaldi10-armeabi-v7a-build为构建32位的目录） 注意:以下为64位命令，如需测试32位，请将arm64-v8a替换为armeabi-v7a。
mount -o remount,rw /
export LD_LIBRARY_PATH=${BUILD_PATH}/../thirdparty/kaldi/kaldi-kaldi10-arm64-v8a-build:$LD_LIBRARY_PATH
cd ${BUILD_PATH}/../thirdparty/kaldi/kaldi-kaldi10-arm64-v8a-build/src
make test
注意:上述BUILD_PATH变量为编译路径，需自行修改为正确的路径
测试用例运行结果如下：
