语音识别实验在训练期间崩溃

标签： machine-learning signal-processing voice-recognition python-bob

我正在尝试使用bob.spear进行演讲者验证实验。

我遇到一个问题，即在训练白化登记者时矛会崩溃。

系统规范：

我在Ubuntu 12.04上，按照网站上的指示安装了矛（即首先添加了bob 1.x存储库，安装了bob，bob-dev，sox，sox-dev包加上依赖项，下载了spear并用它构建了它附加件）。

协定：

我更改了protocol / mobio / mobile0-female文件夹中的文件列表，并创建了类似的配置。 我已将此文件列表和dev / eval / norm文件夹添加到此消息中。

我尝试修复问题的步骤：

  1. 重新安装liblapack（在ubuntu中是liblapack-dev liblapack3g和其他一些我忘记的包）
  2. 重新安装bob.spear并在不同的计算机上运行实验
  3. 将我的wav文件下采样到16k
  4. 确保for_models.lst，for_probes.lst中的dev和eval之间没有重复（虽然这只是为了尝试模仿mobio的竞争文件）
  5. 确保所有文件列表格式正确

    6. 错误日志：

表示输入文件有问题。由于您没有共享文件，因此很难说出究竟是什么问题。可能的问题：

  1. 错误的采样率
  2. 频道数量错误
  3. 导致数值溢出的数据中的零能区

    4. 您需要查看创建警告的文件，并考虑它们可能出现的问题。

答案 1 :(得分：0)

我认为这是一个有用的信息： 信息：#EM终止：达到最大迭代次数。   文件＆＃34; /home/lioruzan/bob.spear-1.1.7/spear/script/spkverif_ivector.py" ;,第728行，主要

也许训练的迭代次数有限，你尝试做更多的事情然后才能处理。 查看您正在使用的应用程序的规范（文档）。应该写一些关于此的内容。

或者它应该是它允许的迭代次数的参数，或者它是硬编码的，你不能使用更多然后是预定义的。
