Analog speech recognition project
Paul D. Smith, Paul E. Hasler · IEEE International Conference on Acoustics Speech and Signal Processing · 2002
The Analog Speech Recognition project combines low-power analog signal processing and digital signal processing theory to provide low-power and robust speech processing systems. This project looks to bring together multiple analog signal processing (ASP) blocks into one large ASP system. These component blocks include an analog cepstrum. vector quantizer, and analog HMM. Finally. there are power dissipation comparisons made between the analog and digital systems based on the computations performed.
