ECE 477 Digital Systems Senior Design Project - Spring 2007 Team1- “DigiSpi” Intelligent Listening Device The “DigiSpi” is an intelligent listening device. For the purpose of novelty, it displays the concept of listening to sound with a microphone and recording only audible speech for later use. The speech is saved on digital camera like storage: an SD card. Enclosed in a discrete packaging, a common lamp, it is able to listen to speech, record audio to the SD card, and playback speech found on the SD card via a headphone or computer speaker output. In addition, the spy-lamp can be contacted using a cell phone, allowing current audio output to be transmitted over a wireless link.
