Now it's time to make fun from what we have learnt

We will make an application that makes us guess a number between 1 and 10 and making the computer as the jury. The computer will speak out whether the number we have input is too high, too low or correct. Firstly, create a new Website on ASP.NET web developer and build a simple interface like below.

Also, include a label, name it as lblGuessedNumber and make it as invisible.

This will store a randomly generated number.

Add the Speech Object Library Object as reference.

To generate a random number, we make use of the Random class. On Page_Load event we place the following code snippet.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles

Try

If Not IsPostBack() Then

Dim number As Integer

Dim rnd As New Random() ' Random number generator

number = rnd.Next(1, 10) ' Generates random number between 1 and 10

' Storing the random number in the hidden label

lblGuessedNumber.Text = number
End If

Catch ex As Exception

Throw ex

End Try

End Sub

Notice that the code is placed inside the Not IsPostBack() if statement as we do not want to generate a random number on every postback. Now, to validate the number that the user has input, we will make use of the following code snippet in the button's click event.

Protected Sub btnGuess_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnGuess.Click

Try

' Variables declaration

Dim voice As New SpVoice

Dim userNumber As Integer

Dim computerNumber As Integer ' Parse the numbers and store then in integer variables

userNumber = Integer.Parse(txtNumber.Text)

computerNumber = Integer.Parse(lblGuessedNumber.Text) ' Speak the verdict

If (userNumber <>

voice.Speak(txtNumber.Text & " is too low!")

ElseIf (userNumber > computerNumber) Then

voice.Speak(txtNumber.Text & " is too high!")

Else

voice.Speak("Cool man! You guessed the correct number!")

End If

Catch ex As Exception

Throw ex

End Try

End Sub

Make ASP.Net Speak Typed Text

Let's start with Microsoft's Speech API (SAPI)

SAPI has a text-to-speech engine (TTS) that we will make use of. In short, SAPI takes text as input and output an audible speech using TTS engine. By the way, every machine with Windows XP has SAPI and TTS.

SAPI is a COM component that needs to be referenced in the project.

Coding Voice Application

First of all, open Microsoft Visual Web Developer and create a new Website. Use the Visual Basic as language. Add a reference to your project. Website > Add Reference > COM > Microsoft Speech Object Library.
Now throw in a text box and a button on your webpage. It may look as below.

The scenario we want to do is to make the computer speak what has been written in the textbox by clicking on the "Speak" button. Double-click on the button to add some code for the button. To access the DLL function, we have to import the namespace SpeechLib as below:

Imports SpeechLib

The next step is to create a SpVoice object.

Dim voice As New SpVoice()

And finally, you can make the computer speak for you!

voice.Speak(txtSpeech.Text)

Below is the complete little code snippet.

Imports SpeechLib

Partial Class _Default

Inherits System.Web.UI.Page

Protected Sub btnSpeak_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSpeak.Click

Try
Dim voice As New SpVoice() ' Creates the voice object

voice.Speak(txtSpeech.Text) ' Speak whatever is written in the textbox

Catch ex As Exception

Throw ex

End Try

End Sub

End Class

Now, you can play around with the voice object by exploring the different methods and properties that the voice object can expose.

To speed up the rate at which the speaker talks, we can do:
voice.Rate = 10
