An analog electronic cochlea
  • R. Lyon, C. Mead
  • Physics, Computer Science
  • IEEE Trans. Acoust. Speech Signal Process.
  • 1 July 1988
An analog electronic cochlea has been built in CMOS VLSI technology using micropower techniques. The key point of the model and circuit is that a cascade of simple, nearly linear, second-order filterExpand

A Low-Power Wide-Dynamic-Range Analog VLSI Cochlea
Low-power wide-dynamic-range systems are extremely hard to build. The biological cochlea is one of the most awesome examples of such a system: It can sense sounds over 12 orders of magnitude inExpand

Trainable frontend for robust and far-field keyword spotting
Robust and far-field speech recognition is critical to enable true hands-free communication. In far-field conditions, signals are attenuated due to distance. To improve robustness to loudnessExpand

A Low-Power Wide-Linear-Range Transconductance Amplifier
The linear range of approximately ±75mV of traditional subthreshold transconductance amplifiers istoo small for certain applications—for example, for filtersin electronic cochleas, where it isExpand

On the importance of time—a temporal representation of sound
5 1 INTRODUCTION The human auditory system has an amazing ability to separate and understand sounds. We believe that temporal information plays a key role in this ability, more important than theExpand

Improved implementation of the silicon cochlea
The original 'Analog electronic cochlea' of R.F. Lyon and C.A. Mead (Trans. Acoust., Speech, Signal Processing, vol.36, no.7, p.1119-34, 1988) used a cascade of second-order filter sections inExpand

  • International Conference on Acoustics, Speech…
  • 3 April 1990
A pitch detector based on Licklider's (1979) duplex theory of pitch perception was implemented and tested on a variety of stimuli from human perceptual tests. It is believed that this approachExpand

  • ICASSP
  • 1 April 1983
Multiple sound signals, such as speech and interfering noises, can be fairly well separated, localized, and interpreted by human listeners with normal binaural hearing. The computational modelExpand
