Harman Kardon has published a preview page for its Microsoft Cortana powered smart home speaker. The perforated cylindrical 'Invoke' looks similar to the Amazon Echo device, aimed at a similar target market. The Harman Kardon Invoke will launch in autumn, coinciding with the release of Windows Redstone 3, notes Thurrott.com.
In its promotional blurb for the upcoming smart home speaker, Harman Kardon writes "At the heart of Invoke is Cortana, your personal digital assistant, helping you stay on top of what?s important. Enhance every moment with captivating sound, voice control your music and smart home, make and receive hands-free calls with Skype, get answers to your questions, and more". Harman Kardon says its "beautifully designed speaker" provides detailed 360-degree sound projection.
