🔒 Closed Help speech recognition

[DavidPhilip]

Help po,, wla naman pong error sa code pero may prompt na ganito pag nag run

Code:

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;
using System.Speech.Recognition;
using System.Speech.Synthesis;
using System.Threading;


namespace trylng
{
public partial class Form1 : Form
{
SpeechSynthesizer ss = new SpeechSynthesizer();
PromptBuilder pb= new PromptBuilder();
SpeechRecognitionEngine sre = new SpeechRecognitionEngine();
Choices clist;
public Form1()
{



InitializeComponent();
}

private void textBox1_TextChanged(object sender, EventArgs e)
{


}

private void button1_Click(object sender, EventArgs e)
{

button1.Enabled = false;
button2.Enabled = true;
clist.Add(new string[]{"hello","how are you","what is the current time","open chrome","thank you","close"});

Grammar gr = new Grammar(new GrammarBuilder(clist));

try
{
sre.RequestRecognizerUpdate();
sre.LoadGrammar(gr);
sre.SpeechRecognized += sre_SpeechRecognized;
sre.SetInputToDefaultAudioDevice();
sre.RecognizeAsync(RecognizeMode.Multiple);

}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "ERROR");

}
}

void sre_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
switch (e.Result.ToString())
{
case "hello":
ss.SpeakAsync("hello david");
break;
case "how are you":
ss.SpeakAsync("i am okay");
break;
case "what is the current time":
ss.SpeakAsync("current time is " + DateTime.Now.ToLongTimeString());
break;
case "thank you":
ss.SpeakAsync("your welcome");
break;


}

textBox1.Text += e.Result.ToString() + Environment.NewLine;

}

private void button2_Click(object sender, EventArgs e)
{
sre.RecognizeAsyncStop();
button1.Enabled = true;
button2.Enabled = false;
}

}
}

May error ka sa

private void button1_Click(object sender, EventArgs e)
{

button1.Enabled = false;
button2.Enabled = true;
clist.Add(new string[]{"hello","how are you","what is the current time","open chrome","thank you","close"});

Grammar gr = new Grammar(new GrammarBuilder(clist));

try
{
sre.RequestRecognizerUpdate();
sre.LoadGrammar(gr);
sre.SpeechRecognized += sre_SpeechRecognized;
sre.SetInputToDefaultAudioDevice();
sre.RecognizeAsync(RecognizeMode.Multiple);

}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "ERROR");

}
}

After inspection may try-catch ka, which means outside the try catch yung error. NullPointerException yung error so it means na it's about a referenced object na walang instance.

After further inspection you called

clist.Add(new string[]{"hello","how are you","what is the current time","open chrome","thank you","close"});

pero wala naman sa code mo na nag create ka ng Choices instance. Try mo mag clist = new Choices(); or whatever, kung pano man siya sa C#, then show the full error kung hindi pa rin nag run
