如何使用 cmu sphinx 分段器类

Question

我正在尝试使用 cmu sphinx 中的分段器类来获取在声音文件中识别语音的时间。但是，我似乎无法让它编译和运行。为了使用分段器，是否需要先配置一些东西？抱歉，我是 CMU Sphinx 的新手。

        boolean noSplit = false;

        for (int i = 0; i < argv.length; i++) {
            if (argv[i].equals("-c")) {

        AudioFileDataSource dataSource = (AudioFileDataSource) cm
                .lookup("audioFileDataSource");
        System.out.println(inputFile);

        WavWriter wavWriter = (WavWriter) cm.lookup("wavWriter");

        frontend.initialize();

        Data data = null;

}

--------------这是我尝试编译时的错误---------- ------------------

常见情况见TranscriberDemo。如果您需要对长音频进行时间对齐，请参阅AlignerDemo。
