1. Universal Voice Activated Remote Control (UVARC) Thanh Phan Dat Le Mohammad Safaiezeab Brandon Wilgor Peter Ralston

2. Project Overview Uses external microphone to receive voice commands Analyzes the input command and compares to wordbank Determines remote control task corresponding to wordbank command Sends command code to external microcontroller Generates and transmits IR signal to the television’s receiver

3. Technical Specifications SpecificationProposed Product Prototype Effective Range15 feet5 feet Battery4 AA batteries3 V Power supply Vocabulary25 words17 words RecognitionSpeaker Independent

4. Project Design Voice Recognition Chip IR Generation Chip

5. IR Signal Generation Consists of PIC18LF2321 microcontroller connected to an IR LED Takes in parallel data from voice recognition chip on Port A Finds corresponding IR signal in memory table Uses timer and pulse width modulator to generate signal Transmits signal on LED

6. Voice Recognition Chip Recognizes keywords at 96% accuracy Listens to any user because of speaker independence Wakes up when activation word “TV” is spoken Matches the next spoken word to a keyword in memory Sends five bits in parallel on Port 2 to IR generation chip

7. Project Status External microcontroller generates the modulated IR signal VR chip recognizes voice commands with high accuracy The two chips are coded and interfaced to communicate Cannot program VR chip with written code

8. Coding Issues VR stamp C code must be compiled by Phyton Phyton demo version –Causes compilation errors –Pins assignments and flags differ from full version VR stamp recognizes wordbank in ROM memory Code to send data to IR chip cannot be compiled Working closely with Phyton customer support Upgrade to full version for development of final product ($3500) –Worth the money because it provides more features –Includes comprehensive documentation and templates

9. Future Work Support one-word universal programming Increase effective microphone range Implement optional button interface Increase memory capacity Support multiple languages Interface with multiple devices (DVD, satellite, stereo, lights, etc.)
