taixzo, is it possible to make a script that listens to mic and prints to output what it heard?

i just thought that this way we'll be able to use scripts to do generic voice recognition to whatever usage anyone likes.

for example, i can record my voice saying "car", get the output recognized text and use it to activate my car mode (even if it was not recognized as "car")

such customization will be awesome and there will be no need for a GUI application for many users.

what do you think?
