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。

示例

# 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

编译

  • 预先准备:

    • cmake >= 3.1

    • 有如下blas接口数学库之一:

      • 建议:mkl

        • 安装 conda,并通过conda安装mkl:conda install mkl(mkl默认会随conda一起安装)
        • 编译时,确保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

    • bin/speech-aligner: 二进制可执行文件,典型调用见egs/cn_phn/run.sh,包括三个参数:
      • 配置:支持通过配置文件和命令行读取参数,建议使用如--config=egs/cn_phn/conf/align.conf
      • 输入:音频列表、对应的文本列表
      • 输出:音素时间对齐标注

应用场景和示例

  • 研究:
    • 为TTS产生音素时间标注的训练数据
      • egs/cn_phn
  • 工程:
    • 歌词对齐
      • egs/cn_lyric [todo]
    • 字幕对齐
      • egs/cn_subtitle [todo]
  • for fun:
    • 鬼畜
      • egs/cn_gc [todo]

更新

  • 增加支持中文拼音(带调)输入,见egs/cn_phn/data/text

Todo

  • 中文环境:标点和英文的处理
  • 增加更多示例

关于

  • 该工程基于著名语音开源项目kaldi,copyright遵循原项目。
  • 示例egs/cn_phn中,使用的音素列表,来自另一个中文词典开源项目DaCiDian

English readme:

speech-aligner, is a tool that generate phoneme-level alignment between human speech and its transcription

Usage example

# 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

Compile

  • requirements

    • cmake >= 3.1

    • one of blas math lib:

      • mkl (recommended)

        • install conda, and use it to install mkl: conda install mkl (mkl is installed with conda by default)
        • when cmake, conda should be in your path
      • atlas

        • 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
  • results

    • bin/speech-aligner: a binary executable file, with arguments:
      • configuration: through config file (recommendation, e.g.: --config=egs/cn_phn/conf/align.conf) or command line
      • inputs: the wav list and the correspoing transcription list (e.g. egs/cn_phn/data )
      • output: the result alignment

Applications

  • for research:
    • generate training data for TTS
      • egs/cn_phn: generate chinese phoneme alignment
  • for engineering:
    • align lyric
      • egs/cn_lyric [todo]
    • align subtitle
      • egs/cn_subtitle[todo]
  • for fun:
    • きちく
      • egs/cn_gc [todo]

About

  • This project is based on a great speech open-source project kaldi.
  • The phonemes used in the environment: egs/cn_phn, come from a chinese dictionary open-source project DaCiDian.
