个别关键短语的分裂假设 [英] Split hypothesis on individual keyphrases

问题描述

我在Android应用中使用Pocketsphinx.我只有相对较小的一组命令可以独立识别，因此最终我使用了从文件中搜索关键字的方式，如下所示:

I use Pocketsphinx in my Android app. I have a relatively small set of commands to be recognized independently, so I ended up using a keyword search from a file that looks like this:

one/1.0/
done/1.0/
recognition on/1e-10/
recognition off/1e-10/

实际列表不是英语的，因此为示例起见，可以任意选择这些关键字.我意识到这些阈值可能不是最佳阈值，而且简短的单词容易出现不匹配的情况.

The actual list is not in English so these keywords are chosen arbitrarily for the sake of the example. I realize that these thresholds may be somewhat less than optimal, and that short words are prone to mismatches.

此方法出现问题:

@Override
public void onPartialResult(Hypothesis hypothesis) {
    if (hypothesis != null) {
        Log.d(
                "Sphinx",
                "\"" + hypothesis.getHypstr() + "\" recognized"
        );
    }
}

请注意，有些单词听起来很相似.事情是

Note that some words sound pretty much alike. The thing is,

• 一个"导致完成一个"被识别
• 完成"导致已完成"被识别

不幸的是，我在 hypstr_get 上找不到任何文档(如果能直接引导我，我将不胜感激)，但实际上，它似乎以概率增加的顺序返回了可能匹配的字符串

Unfortunately, I couldn't find any documentation on hypstr_get (I would appreciate if you could direct me to it) but effectively it seems to return a joined string of probable matches in increasing order of probability.

如何从假设中检索实际命令?我不能只将 hypothesis.getHypstr()用空格分开，因为某些命令是关键字而不是关键字.我只想要一个最可能的结果.

How can I retrieve actual commands from hypothesis? I can't just split hypothesis.getHypstr() by whitespace since some commands are keyphrases rather than keywords. I only want a single, most probable result.

谢谢.

推荐答案

您可以迭代细分，每个细分都是关键字

You can iterate over segments, each would be a keyword

    for (Segment seg : recognizer.getDecoder().seg()) {
        System.out.println(seg.getWord() + " " + seg.getProb());
    }
