How do I call or chat with someone on Skype using Siri on my iOS device?
With iOS 10 and SiriKit, you can call and chat with someone on Skype using the same voice commands you’re used to using already. Let’s say you’re trying to contact Lisa Smith on Skype. If you have her Skype contact information saved on your iOS device, all you have to say is "Message Lisa on Skype" or “Call Lisa on Skype.” If Siri needs clarification on the name of the contact, it may ask you to confirm the right one. After you tap the contact you want, your Skype chat or call is initiated.
You need to have "Hey Siri" enabled on your iOS device to use this feature. Skype is not responsible for the content of external sites.
