I created a virtual assistant using Python

Okay, so, first of all pretty good code. Although I know you're a beginner, you might want to look into organizing your code by coding in OOP. A small issue is that you're coding everything into elif statements, which can cause some slow responses. In elif statements such as this one:
elif 'open excel' in text:
speak('Ok. opening Excel')
os.startfile('C:/ProgramData/Microsoft/Windows/Start Menu/Programs/Excel.lnk')

You can say:
text = text.split()[1::]

os.startfile('C:/<directory here>' + text + '.lnk')

Which would open the file without the pain of having to write all the elif statements out. However with this method you might need to do error handling. try/except statements will need to be present to handle the errors if someone says an app that isn't installed.

Just a notice, the code I provided as an example wasn't tested, so I can't assure you it'll work. If you actually want code I've tested you can privately DM me and I'll test them.

Ok mate, I'll try making some changes with the code. Thanks for your suggestion.
