如何听写过程中获得候补单词语的SAPI 5.4使用C＃？ [英] How to get alternate single words during dictation in SAPI 5.4 using C#?

问题描述

我运行语音识别和新技术，用户研究。在实验室测试中，我需要用我编程接口来显示所有的听写文本。

I am running a user study with speech recognition and new technologies. During the laboratory tests, I need to display all the dictated text using an interface that I programmed.

目前，我可以在C＃中备用整个句子，但我需要获得单个单词。例如，如果有人说你好，我的名字叫安德鲁，我想获得一个替代词你好，我的，姓名，是，并为完整的安德鲁，而不是替代判决。

Currently, I can get the alternate whole sentences in C# but I need to get the single words. For example, if someone says "Hello, my name is Andrew", I want to get an alternate word for "Hello", "my", "name", "is" and "Andrew", instead of an alternate for the complete sentence.

下面是我使用的处理程序的代码片段。

Here is a code snippet of the handler I'm using.

public void OnSpeechRecognition(int StreamNumber, object StreamPosition, SpeechRecognitionType RecognitionType, ISpeechRecoResult Result)
{
    int NUM_OF_ALTERNATES = 5; // Number of alternates sentences to be read
    string recognizedSentence = Result.PhraseInfo.GetText(0, -1, true);

    // Get alternate sentences
    ISpeechPhraseAlternates phraseAlternates = Result.Alternates(NUM_OF_ALTERNATES);
}

任何想法表示赞赏。

Any ideas are appreciated.

推荐答案

您需要指定元素计数，并在Result.Alternates指数调用。

You need to specify the element count and index in the Result.Alternates call.

例如，

public void OnSpeechRecognition(int StreamNumber, object StreamPosition, SpeechRecognitionType RecognitionType, ISpeechRecoResult Result)
{
    int NUM_OF_ALTERNATES = 5; // Number of alternates sentences to be read
    string recognizedSentence = Result.PhraseInfo.GetText(0, -1, true);

    // Get alternate sentences
    int elementCount = Result.PhraseInfo.Elements.Count();
    for (int i = 0; i < elementCount; ++i)
    {
          ISpeechPhraseAlternates phraseAlternates = Result.Alternates(NUM_OF_ALTERNATES, i, 1);
    }
}
