Authors’ note: We want to thank to our colleagues for helping us improve our limited resources on embedded speech implementation. We especially thank Mr. Florin Popescu for sharing his expertise in speech synthesis techniques.
Nicusor Birsan has developed embedded systems for more than a decade. He now shares this experience with his students at the Military Technical Academy in Bucharest, Romania.
Ionut Tarsa is an undergraduate student at the Military Technical Academy. He is fascinated by the fantastic domain of embedded systems. Ionut also enjoys playing sports, listening to good music, watching movies, and reading.
