A stop by the FCC has given us more of a look at Harman Kardon's upcoming Cortana-powered speaker, Invoke.

Harman Kardon's Cortana-powered Invoke speaker was officially announced in May, but information on the device has been scant since. Now, however, the device has made a trip to the FCC, which has revealed (via MSPU) some new specifications, the Invoke's user manual, and some new pictures.

According to the Invoke's user manual, it supports AAC, MP3, Vorbis, FLAC, WMA and WAV audio formats. In what is probably no surprise, both Bluetooth 4.1 and 802.11ac wireless are supported as well. More interestingly, the Invoke packs a total of 6 speakers, including 3 45mm woofers and 3 13mm dome tweeters. Lastly, the Invoke comes in at 9.5-inches tall and weighs 2.3 pounds.

Aside from pictures and measurements of the device in-person, a diagram labeling and showing the position of its various buttons is available as well. Most interesting is the top portion of the device, which is a touch area that also lights up when Cortana is listening, as seen in Harman Kardon's initial teaser. And while you can interact with the Invoke with only your voice, the touch area will also let you do things like answer or end Skype calls, stop music, or turn off an alarm with just a tap.

There's no price or precise release date set for the Harman Kardon Invoke just yet, but the company did reveal its target timeframe is sometime this fall. We're also expecting to see Cortana speakers from other manufacturers, including HP which gave us an early peek at its efforts during Computex.
