语音识别WAV To String
由于项目需要在网上找了好多,修改下,下面是个样例,大家看下
1 using System; 2 using System.Collections.Generic; 3 using System.Text; 4 using DotNetSpeech; 5 using System.Threading; 6 7 namespace TestSpRecognize 8 { 9 class Program 10 { 11 static void Main(string[] args) 12 { 13 WavToCaption obj = new WavToCaption(); 14 obj.openWAV(); 15 } 16 } 17 class WavToCaption 18 { 19 private SpInProcRecoContext m_wavRecoContext; 20 private ISpeechRecoGrammar m_Grammar; 21 private SpFileStream m_infile; 22 23 public WavToCaption() 24 { 25 SpInprocRecognizer recognizer = new SpInprocRecognizer(); 26 m_wavRecoContext = (SpInProcRecoContext)recognizer.CreateRecoContext(); 27 m_wavRecoContext.RetainedAudio = SpeechRetainedAudioOptions.SRAORetainAudio; 28 m_infile = new SpFileStreamClass(); 29 m_infile.Format.GetWaveFormatEx(); 30 } 31 32 public void openWAV() 33 { 34 m_Grammar = m_wavRecoContext.CreateGrammar(0); 35 m_Grammar.DictationLoad("", SpeechLoadOption.SLOStatic); 36 37 //register an event handler everytime the engine recognizes something from teh file 38 m_wavRecoContext.Recognition += new _ISpeechRecoContextEvents_RecognitionEventHandler(RecoContext_Recognition); 39 40 41 //register an event handler when the engine is done reading the file 42 m_wavRecoContext.EndStream += new _ISpeechRecoContextEvents_EndStreamEventHandler(RecoContext_EndRecognition); 43 44 //try to open the file 45 try 46 { 47 m_infile.Open(@"c:\1.wav", 48 SpeechStreamFileMode.SSFMOpenForRead, false); 49 Console.Out.WriteLine("Succesfully opened file"); 50 } 51 catch (Exception e) 52 { 53 Console.Out.Write("Could not find file"); 54 return; 55 } 56 57 //this makes it so the engine recognizes we're reading in from a wav, vs. a microphone 58 m_wavRecoContext.Recognizer.AudioInputStream = m_infile; 59 60 //starts reading the file here 61 m_Grammar.DictationSetState(SpeechRuleState.SGDSActive); 62 Console.ReadKey(); 63 64 } 65 66 void RecoContext_Recognition(int StreamNumber, object StreamPosition, SpeechRecognitionType RecognitionType, ISpeechRecoResult Result) 67 { 68 //Result.PhraseInfo.GetText(0, -1, true); 69 Console.Out.Write("recognized something"); 70 Console.ReadKey(); 71 } 72 73 void RecoContext_EndRecognition(int StreamNumber, object StreamPosition, bool f) 74 { 75 m_infile.Close(); 76 m_Grammar.DictationSetState(SpeechRuleState.SGDSInactive); 77 78 } 79 80 81 }
这个是测试可用的
