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”

End Select
Save the file as Talking Calculator.vbs for the example above and do not forget to change the file type from text to All files from drop down menu in Notepad before saving it. Obviously, you can save with any name you like.
The red texts are what the computer will speak in Talking Calculator option.
Double clicking the file will bring the Talking Calculator.
Get this Talking Calculator in right click context menu in Windows 7
Place the Talking Calculator vbs file created in the previous step at the root of C drive.
Open Notepad, copy paste the following and modify as per your need:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOTDirectoryBackgroundshellTalking Calculator]
“Icon”=”C:WindowsSystem32Narrator.exe”
“Position”=”Bottom”[HKEY_CLASSES_ROOTDirectoryBackgroundshellTalking Calculatorcommand]
@=”Wscript.exe “C:Talking Calculator.vbs””
Save the file as Add Talking Calculator.reg and do not forget to change the file type from text to All files from drop down menu in Notepad before saving it. Name does not matter here at all. You can save as you like.
Now, double click the reg file and accept the security warnings and you will see the Talking Calculator option in right click context menu when clicked on a folder or any empty place inside folder or Windows 7 desktop.
Removal of Talking Calculator option from the right click menu:
Add a minus sign before the H starts after the third bracket; like [-HKEY_CLASSES…. to all where there is HKEY and save it (with some good name) as reg file and run it.

“The red texts are what the computer will speak in Talking Calculator option.”
Well, either have I or Chrome gone colour blind……….. :) Will you fix so there will be red text?
You actually seeing a cached page. In that, the text were not marked red.
We will flash the cache after 5-6 hours (Sorry for the late, a high load is on the server right now); you will be able to see the red things :)
So, please visit after 4 hours and clear your browser’s cache too; you’ll be able to see. Thank you for pointing the bug.
Thanks, now I see red :)
Thats nice!
