C#使用微软的库实现语音识别转文字
using System;
using System.Speech.Recognition;
class Program
{
static void Main()
{
// 创建语音识别引擎
SpeechRecognitionEngine recognizer = new SpeechRecognitionEngine();
// 配置语法
Choices commands = new Choices();
commands.Add(new string[] { "hello", "open notepad", "close notepad", "exit" });
GrammarBuilder grammarBuilder = new GrammarBuilder(commands);
Grammar grammar = new Grammar(grammarBuilder);
// 将语法添加到识别引擎
recognizer.LoadGrammar(grammar);
// 设置事件处理程序来处理识别结果
recognizer.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);
// 启动语音识别
recognizer.SetInputToDefaultAudioDevice();
recognizer.RecognizeAsync(RecognizeMode.Multiple);
Console.WriteLine("Listening for commands. Press Enter to exit.");
Console.ReadLine();
// 停止识别并释放资源
recognizer.RecognizeAsyncStop();
recognizer.Dispose();
}
private static void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
if (e.Result != null && e.Result.Confidence > 0.6)
{
string recognizedText = e.Result.Text;
Console.WriteLine("Recognized: " + recognizedText);
// 在此处可以根据 recognizedText 执行相应的操作
// 例如，执行命令、触发事件等
}
}
