NEED HELP! send sms to cellphone and voice control?

Hey friends, I’ve read recently that openhab can send sms to cellphone but I dont know how exactly to do that, the information given in this : https://my.openhab.org/docs/notifications seems too vague. Can anybody show me elaborately the configuration steps needed to send a basic sms to my cellphone? Thanks a lot!

And one more thing, can anyone suggest me some softwares used for voice recognition on raspberry pi 3? I am trying install Jasper but failed several times…
Thanks a lot!
I’m just a student and I hope you could help me figure something new out!!!
