Data Sheet Voice Activated e Block Description Features

Data Sheet Voice Activated e. Block Description: Features: We have created a Voice activated e. Block. This e. Block is designed to output a Yes or No depending on the spoken commands of the user. Voice Recognition Features To enable use of multiple voice e. Blocks in close proximity, each e. Block is given a name (user-defined). This prototype has set name in the firmware but a future prototype could include dip-switches to allow the user to choose a different name. • Effective range of 1 to 6 feet with slightly raised voice in a low noise environment. To operate the e. Block a user needs only to speak in a clear, normal voice, atleast 1 foot away from the microphone, the e. Blocks name (in this case “one”) and the desired output (“Yes” or “No”). The e. Block would then output that desired value. The e. Block has a red LED attached, this is to inform the user that the e. Block has recognized it’s own name and is awaiting the output command. The e. Block will continue to output this value until it is told to change. Voice recognition functionality is provided by Sensory’s Voice Extreme IC. Communication between the Voice Extreme and other e. Block is implemented on a PIC microcontroller. • Speaker Independent Voice Recognition. • 97% accurate. Low Power Requirement • Vdd = 2. 85 v – 5. 00 v • Idd = 11. 66 m. A @ 3 v (Average) • Lasts about 40 days on 2 AA (2100 m. AH) rechargeable Ni-MH batteries. e. Block Voice Recognition System • Fully modular design for quick replacement of critical components. • Low cost approx $10 – $15 batteries not included. • RS-232 Interface.
