Laboratoriya ishi №1 Mavzu: C# asosida nutqni tanish algoritmlarini o’rganish Ishdan maqsad

Amaliy qism: Endi esa nutqni tanishga oid C# da bitta misol ko’ramiz.

Nutqni tanishni initializatsiya qilamiz:

 

// Create a new SpeechRecognizer instance.

SpeechRecognizer sr = new SpeechRecognizer();

Nuqtni tanish grammatikasini yaratamiz:

Choices colors = new Choices();

colors.Add(new string[] {"red", "green", "blue"});

GrammarBuilder gb = new GrammarBuilder();

gb.Append(colors);

// Create the Grammar instance.

Grammar g = new Grammar(gb);

Nutqni tanishni ichiga grammatikadan yuklaymiz:

sr.LoadGrammar(g);

Nutqni tanishni natijasi hodisasi uchun registr:

sr.SpeechRecognized += new EventHandler(sr_SpeechRecognized);

Nutqni tanishni natijasi hodisasini yaratish:

void sr_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)

{

MessageBox.Show(e.Result.Text);

}

Yuqoridagilar bo’yicha misol:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

using System.Speech.Recognition;

namespace WindowsFormsApplication1

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

// Create a new SpeechRecognitionEngine instance.

SpeechRecognizer recognizer = new SpeechRecognizer();

// Create a simple grammar that recognizes "red", "green", or "blue".

Choices colors = new Choices();

colors.Add(new string[] { "red", "green", "blue" });

// Create a GrammarBuilder object and append the Choices object.

GrammarBuilder gb = new GrammarBuilder();

gb.Append(colors);

// Create the Grammar instance and load it into the speech recognition engine.

Grammar g = new Grammar(gb);

recognizer.LoadGrammar(g);

 

// Register a handler for the SpeechRecognized event.

recognizer.SpeechRecognized +=

new EventHandler(sre_SpeechRecognized);

}

// Create a simple handler for the SpeechRecognized event.

void sre_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)

{

MessageBox.Show("Speech recognized: " + e.Result.Text);

}
