Adding voice command capability to a remote control makes a lot of sense. With well-thought-out voice control, finding buttons to watch a favorite movie, or fast forward, pause or stop, is not so challenging and frustrating.
After all, if our TVs have gotten so smart, why are the remotes so dumb?!
Our ZigBee Remote Control Reference Design (part number: EM34X-VREVK) supports voice control, Infrared (IR) control with IR database, a backlit keyboard, and an acceleration sensor for activating the backlight. It’s a slick remote control and has is in mass production with one of our leading customers, a large remote control provider.
The remote is designed to be cost efficient while supporting the requirements of various cloud-based “voice-to-text” software providers. Voice control typically requires an internet connection to transmit the voice command into the could where it is converted to text. This is the model many service providers have adopted, and the remote supports these specifications as shown in the table below.
One way we saved money for our customer and others who adopt this remote control is by integrating the standalone codec functionality and bill of materials (BOM) into our ZigBee SOC, the EM341. According to Digi-Key pricing, this can save between $0.50 and $1.50 per device by removing the standalone codec and its BOM, of course the savings depend on the volumes for the remote control.
The reference design is orderable and configurable for both hardware codec and software codec. Find more information on Silicon Labs ZigBee Remote Control solutions at http://bit.ly/1O4YdED
