我在开发微信小程序时，想实现语音控制。但是微信客户端提供的音频是丝绸的。

我需要将 Silk 文件转换为第三语音检测服务可以识别的某种格式。

一些第 3 服务支持 amr 格式。这真的很棒，因为尺寸可能非常小。

On MacOS, the procedure is working for converting silk to mp3, you may manipulate a little bit and test on other OS for amr.

  1. Download lame http://lame.sourceforge.net/, run

    ./configure && make && sudo make install

    If you encounter 

    Undefined symbols for architecture x86_64:
"_lame_init_old", referenced from:
 -exported_symbol[s_list] command line option
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
    Remove line lame_init_old from ${lame}/include/libmp3lame.sym before ./configure

  2. Download ffmpeg from http://ffmpeg.org/, run

    ./configure --enable-libmp3lame && make && sudo make install

    If you encounter 

    nasm/yasm not found or too old. Use --disable-x86asm for a crippled build.
    . Then run brew install yasm before ./configure

  3. Download https://github.com/kn007/silk-v3-decoder

  4. Run the command to convert silk to mp3.

    ${your-silk-v3-decoder-folder}/converter.sh {silk file full path} mp3 And you will see the mp3 file in the same path as the input silk. And the path to silk file MUST be full path.
