## Creating the Talking Calculator VB Script

We have modified to add voice function to a existent VB Script calculator created by an unknown developer. Please let us know his / her name, we will give the credit for the Calculator function. We have added the voice function and all other things.

Open Notepad. Write the following things for making your **Talking Calculator**:

Set wshshell=wscript.createobject(“wscript.shell”)

Set Sapi = Wscript.CreateObject(“SAPI.SpVoice”)

set ObjVoice = CreateObject(“SAPI.SpVoice”)

Dim msg,input

Sapi.speak “Choose System of Calculation and hit OK”

msg = “Choose System of Equations:” & vbCR

set ObjVoice = CreateObject(“SAPI.SpVoice”)

ObjVoice.Speak StrText

msg = msg & “” & vbCR

msg = msg & “1. Multiplication ” & vbCR

msg = msg & “2. Addition ” & vbCR

msg = msg & “3. Division ” & vbCR

msg = msg & “4. Subtraction ” & vbCR

msg = msg & “5. Absolute Value ” & vbCR

msg = msg & “6. Raising to a Power” & vbCRinput = InputBox(msg,”Calculator Main Menu”)

SdrText=(“You have chosen ” + input)

Select Case inputcase “1”

Dim a, b, sum

Sapi.speak “Input your first number to be multiplied and hit OK”

a=inputbox(“Input your first number to be multiplied.”, “Multiplication- First Number”, “Enter your number”)

Sapi.speak “Input your second number to be multiplied and hit OK”

b=inputbox(“Input your second number to be multiplied.”, “Multiplication-Second Number”, “Enter your number”)

if not isnumeric (a) then

a = false

end if

If a = vbCancel then

wscript.quit

end if

if not isnumeric (b) then

b = false

end if

If b = vbCancel then

wscript.quit

end if

Sapi.speak “The product of the two digits you entered is”

c=msgbox(“Your Answer: “& a * b, vbInformation, “Product”)case “2”

Sapi.speak “Input your first number to be Added and hit OK”

a=inputbox(“Input your first value to be added.”, “Addition- First Value”, “Enter your number”)

Sapi.speak “Input your second number to be Added and hit OK”

if not isnumeric (a) then

end if

a = false

end if

If a = vbCancel then

wscript.quit

end if

Sapi.speak “Input your the desired exponent as the second value. It can be of, any value from 0 to 10”
