Perhaps you're thinking of:
* Alexa: Amazon's virtual assistant. You can activate it with "Alexa" and then give commands like "Play music," "Set a timer," or "What's the weather?"
* Siri: Apple's virtual assistant. You can activate it with "Hey Siri" and then give commands like "Make a call," "Send a text," or "Set a reminder."
* Google Assistant: Google's virtual assistant. You can activate it with "Hey Google" and then give commands like "Navigate to the nearest coffee shop," "Read my emails," or "Play my favorite playlist."
If you have a specific virtual assistant in mind, please let me know the name, and I can provide you with the correct commands.
Please note that I cannot provide you with commands for a virtual assistant that doesn't exist.
