Question

我正在使用android-alize作为演讲者识别应用。正如文档所说，我正在尝试如下训练模型，

//将音频发送到系统 alizeSystem.addAudio（音频）;

//使用音频训练模型 alizeSystem.createSpeakerModel（ “有人”）;

但是我的应用程序崩溃了下面的stacktrace，

进一步调试Alize-LIA_RAL，我意识到android项目在assets / gmm / world.gmm中查找world.gmm（UBM）。好像我们必须使用LIA_RAL库生成这个world.gmm，然后将其添加到android代码中。

但是，我们必须在alize初始化期间使用下面给出的代码片段指定UBM位置。

    InputStream backgroundModelAsset = null;
    try {
        backgroundModelAsset = context.getAssets().open("gmm/world.gmm");
        alizeSystem.loadBackgroundModel(backgroundModelAsset);
        backgroundModelAsset.close();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (AlizeException e) {
        e.printStackTrace();
    }

我设法从谷歌搜索中找到了一个world.gmm，当我将它添加到我的android项目时，错误消失了。然而，预测并不准确。

因此，我正在进一步研究LIA_RAL源代码，通过提供满足我要求的音频数据（音频样本）来生成这个world.gmm（UBM）。

执行alizeSystem.createSpeakerModel（userName）时出现“未找到UBM”的崩溃;
