speech-aligner,是一个从“人声语音”及其“语言文本”,产生音素级别时间对齐标注的工具。
# 调用 bin,输入语音列表和文本、输出对齐结果
cd egs/cn_phn
speech-aligner --config=conf/align.conf data/wav.scp data/text data/out.ali
# 查看输出对齐结果,包含: 文件名,音素时间起点(秒) 音素时间终点(秒) 音素
cat data/text data/out.ali

预先准备:
cmake >= 3.1
有如下blas接口数学库之一:
建议:mkl
conda install mkl
(mkl默认会随conda一起安装)conda
可执行(which conda
有输出)atlas
ubuntu安装: sudo apt-get install libatlas3-base
linux发行版众多,数学库路径不一且变动,所以可以通过如下命令进行路径指定:
cmake -DBLAS_VENDORS=ATLAS -DBLAS_ATLAS_LIB_DIRS=[/path/to/atlas/lib ..
OSX系统(Darwin)自带Accelerate framework,可调过这项
…其他数学库,可查看cmake/Modules/FindBLAS.cmake
,了解支持的数学库
cmake编译
git clone .../speech-aligner.git
cd speech-aligner
mkdir build && cd build
cmake ..
make -j
编译结果
--config=egs/cn_phn/conf/align.conf
speech-aligner, is a tool that generate phoneme-level alignment between human speech and its transcription
# call the bin,with speech and transcript as inputs
./bin/speech-aligner --config=egs/cn_phn/conf/align.conf egs/cn_phn/data/wav.scp egs/cn_phn/data/text egs/cn_phn/data/out.ali
# check the output alignment, include: filename, phoneme and its start/end time
cat egs/cn_phn/data/text egs/cn_phn/data/out.ali

requirements
cmake >= 3.1
one of blas math lib:
mkl (recommended)
conda install mkl
(mkl is installed with conda by default)conda
should be in your pathatlas
ubuntu: sudo apt-get install libatlas3-base
when cmake, it maynot find your atlas automatically, thus you need set the math lib path as below:
cmake -DBLAS_VENDORS=ATLAS -DBLAS_ATLAS_LIB_DIRS=[/path/to/atlas/lib ..
Accelerate framework (need do nothing for "macOS/Darwin")
...
cmake
git clone .../speech-aligner.git
cd speech-aligner
mkdir build && cd build
cmake ..
make -j
