Here's a cure for "texting thumb:" Use your lips.
Starting Friday, AT&T is letting its mobile subscribers dictate and send text messages over devices powered by Amazon's Alexa assistant. Those include the Echo and the Echo Dot.
The service, known as a "Skill," allows customers of the mobile phone network to store up to 10 contacts in the app's memory. To send a message, say, "Alexa, send text to" one of the stored names and dictate.
Amazon's Alexa, if you haven't guessed it already, is a voice-activated assistant that can be used to play music, get weather info and control a smart home. You can even get recipes through the AI assistant.
