低语音识别准确度...... [英] Low speech recognition accuracy...

问题描述

大家好，



我创建了一个连续语音识别程序，但其准确性非常低。请帮我。我写的代码是问题吗？

Hi All,

I am created a program for continuous speech recognition, but its accuracy is very low. Please help me. I have written code that is the problem?

using SpeechLib;

namespace Speech_Recognition
{
    public partial class SRForm : Form
    {
        private SpeechLib.SpSharedRecoContext objRecoContext;
        private SpeechLib.ISpeechRecoGrammar grammar;
        public SRForm()
        {
            InitializeComponent();
            initSAPI();
        }

        private void initSAPI()
        {
            try
            {
                //Create Instance The Main Object (SpSharedRecoContext)And Activating The Recognition Event
                objRecoContext = new SpeechLib.SpSharedRecoContext();
                objRecoContext.Recognition += new _ISpeechRecoContextEvents_RecognitionEventHandler(RecoContext_Recognition);
                objRecoContext.EventInterests = SpeechLib.SpeechRecoEvents.SRERecognition | SpeechLib.SpeechRecoEvents.SREAudioLevel;
                //Grammar Creation with Default Value 'ID = 0' And Grammar Activation
               grammar = objRecoContext.CreateGrammar(0);
               grammar.DictationSetState(SpeechRuleState.SGDSActive);
            }
            catch (Exception ex)
            {
                MessageBox.Show("Exception \n" + ex.ToString(), "Error - initSAPI");
            }
        }
        //---------------------------------------------------------------------------------------------------------

        //Main ObjRecoContext Event And launched when engine recognized a phrase
        public void RecoContext_Recognition(int StreamNumber, object StreamPosition, SpeechRecognitionType RecognitionType, ISpeechRecoResult e)
        {
            //Get And Display Phrase
            string phrase = e.PhraseInfo.GetText(0, -1, true);
           richTextBox1.Text+= phrase + " ";
        }
    }
}

先谢谢。

Thanks in Advance.

什么都做不了。这是您现在使用的识别引擎的质量。或者，您可以使用 System.Speech.Recognition ， http://msdn.microsoft.com/en-us/library/system.speech.recognition.aspx [ ^ ]，带 DictationGrammar 。这比较简单，但是资格也是一样的。



如果一次使用的所有语法都合理地小，引擎提供了相当好的质量，并且所有作品中使用的所有作品在发音方面都截然不同。这不是 DictationGrammar 的情况，其中看起来相似的数量是巨大的。



A已阅读科学美国人的文章声称原始的Nuance Dragon NaturallySpeaking提供了非常流畅的听写，从未尝试过： http://en.wikipedia.org/wiki / Dragon_NaturallySpeaking [ ^ ]。



我还不熟悉其他一些产品。请参阅：

Nothing can be done. This is the quality of the recognition engine you use right now. Alternatively, you could use System.Speech.Recognition, http://msdn.microsoft.com/en-us/library/system.speech.recognition.aspx[^] with DictationGrammar. This is simpler, but the qualify will be the same.

The engine provide pretty good quality if all the grammars used at a time and taken together are reasonably small, and all the works used in all of them are distinctly different in pronunciation. This is not a case with DictationGrammar, where the number of looks-alike is enormous.

A have read the article in Scientific American claiming that original Nuance Dragon NaturallySpeaking provides really smooth dictation, never tried: http://en.wikipedia.org/wiki/Dragon_NaturallySpeaking[^].

There is a number of other products I''m not familiar with. See:
http://en.wikipedia.org/wiki/Speech_recognition[^],
http://en.wikipedia.org/wiki/Digital_dictation[^],
http://en.wikipedia.org/wiki/Digital_dictation_software[^].
