我正在使用一个简单的语音识别应用程序来通过并行端口控制继电器,这是它应该如何工作的基本程序。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Speech.Synthesis;
using Microsoft.Speech.Recognition;
namespace speechHardware
{
class Program
{
static void Main(string[] args)
{
// Create a new SpeechRecognitionEngine instance.
var sre = new SpeechRecognitionEngine();
SpeechSynthesizer s = new SpeechSynthesizer();
Console.WriteLine("starting recognizer.......");
s.Speak("starting recognizer.");
// Create a simple grammar that recognizes "light on", "light off", or "fan on","fan off".
Choices colors = new Choices();
Console.WriteLine("option list.......");
colors.Add("light on");
colors.Add("light off");
colors.Add("fan on");
colors.Add("fan off");
GrammarBuilder gb = new GrammarBuilder();
gb.Append(colors);
Console.WriteLine("starting grammer builder.......");
// Create the actual Grammar instance, and then load it into the speech recognizer.
Grammar g = new Grammar(gb);
sre.LoadGrammar(g);
// Register a handler for the SpeechRecognized event.
sre.SpeechRecognized += SreSpeechRecognized;
//sre.SetInputToWaveFile("C:\Users\Raghavendra\Documents\MATLAB\test.wav");
sre.SetInputToDefaultAudioDevice();
Console.WriteLine("input device recognised.......");
s.Speak("input device recognised.");
sre.RecognizeAsync(RecognizeMode.Multiple);
Console.ReadLine();
Console.WriteLine("stopping recognizer.....");
sre.RecognizeAsyncStop();
}
static void SreSpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
SpeechSynthesizer s = new SpeechSynthesizer();
Console.WriteLine("\nSpeech Recognized: \t{0}" + e.Result.Confidence, e.Result.Text);
if (e.Result.Confidence < 0.85)
return;
switch (e.Result.Text)
{
case "light on":
light(1);
s.Speak("the light has been turned on.");
break;
case "light off":
light(0);
s.Speak("the light has been turned off.");
break;
case "fan on":
fan(1);
s.Speak("the fan has been turned on.");
break;
case "fan off":
fan(0);
s.Speak("the fan has been turned off.");
break;
default:
break;
}
}
static void light(int val)
{
Console.WriteLine("\nSpeech Recognized:light ");
}
static void fan(int val)
{
Console.WriteLine("\nSpeech Recognized: fan");
}
}
}
这在我朋友的电脑上完美运行,但在我的电脑上它无法识别我所说的内容,也许它没有得到输入。我们都有几乎相同的配置。麦克风也很好用,我不知道出了什么问题。
我已安装 Microsoft 语音平台 - 软件开发工具包 (SDK),版本 10.2(x86 版) Microsoft 语音平台 - 服务器运行时,版本 10.2(x86 版)
请帮帮我。
