Speaking Scripts With NirCmd

Nir Sofer has written a fun utility that I have been using to make my scripts talk.  Its called nircmd.exe

NirCmd is a small command-line utility that allows you to do some useful tasks without displaying any user interface. By running NirCmd with simple command-line option, you can write and delete values and keys in the Registry, write values into INI file, dial to your internet account or connect to a VPN network, restart windows or shut down the computer, create shortcut to a file, change the created/modified date of a file, change your display settings, turn off your monitor, open the door of your CD-ROM drive, and more…

Text-To-Speach is available at least as far back as Windows XP. I’m not sure how to call it directly, but using nircmd it is as simple as

1
nircmd speak text "Hello" 2 60

The parameters are the speed and the volume of the narrator. To add narration to my scripts I call :SPEAK instead of echo to write to the console.

:SPEAK
where nircmd.exe /Q
if %errorlevel% neq 0 (
echo %~1
) else (
nircmd speak text "%~1" 2 60
)
EXIT /B

When handling exceptions during my build scripts, I use this :NOTIFICATION routine to call my speech routine to alert me if I am within earshot.

REM = NOTIFY - indicate failure

:NOTIFY
echo Error occurred with code %~1
CALL :SPEAK "Error occurred with code %~1"
SET Error=%~1
EXIT /B

After executing MSBuild, I check for errors and notify myself audiably if there is a problem.
