有没有人知道如何使用 Microsoft 的语音识别 API for Windows Form Application 进行 STT?
最佳答案
.NET 包含用于语音识别的程序集。
您需要将引用添加到
并添加命名空间
using System.Speech.Recognition;
以下代码将分析您的语音并将文本添加到文本框中:
private void startRecognition()
{
SpeechRecognitionEngine recognizer = new SpeechRecognitionEngine(); //default culture
//SpeechRecognitionEngine recognizer = new SpeechRecognitionEngine(new CultureInfo("de-DE"));
//With specified culture | Could cause an CultureNotFoundException
Grammar dictationGrammar = new DictationGrammar();
recognizer.LoadGrammar(dictationGrammar);
try
{
recognizer.SetInputToDefaultAudioDevice();
RecognitionResult result = recognizer.Recognize();
if(result != null)
result_textBox.Text += result.Text + "\r\n";
}
catch (InvalidOperationException exception)
{
MessageBox.Show(exception.Message,exception.Source);
}
finally
{
recognizer.UnloadAllGrammars();
}
}
要更改识别超时的时间,请更改以下属性:
recognizer.InitialSilenceTimeout = TimeSpan.FromSeconds(3);
recognizer.BabbleTimeout = TimeSpan.FromSeconds(2);
recognizer.EndSilenceTimeout = TimeSpan.FromSeconds(1);
recognizer.EndSilenceTimeoutAmbiguous = TimeSpan.FromSeconds(1.5);
