searching article, paper or book summarizing recent findings on the active cochlea / OHC

[bert hubert <ahu@xxxxxxx>]

Dear researchers,

I'm doing research on (very) small vocabulary speaker independent untrained
speech recognition [1] and left the well travelled path of FFT for simulated
oscillators.

Faced with the 'Cochlear Paradox' [2] of conflicting goals for Q (frequency
specificity) and Tau (relaxation time), I'm looking for biological
inspiration.

In trying to get into phase with the field, I find a lot of work from
differing timeperiods, some frankly contradicting. It appears the CA
controversy has died out and that the cochlea is now widely regarded as
being 'active', but other issues appear to be less balanced.

So what I'm looking for is a recommended reference to an article
summarizing recent findings regarding the 'active cochlea'. I'm less
interested in the full biological gory details than in the mechanical
workings.

I also read http://www.bcm.tmc.edu/oto/research/cochlea/Volta/16.html and
I'm wondering if this reflects the state of the art.

Somewhat older papers also mention gammatone filterbanks, are these still
hot?

Thank you for your time. I don't have a lot to offer in return, but some of
you may be able to benefit from http://ds9a.nl/gcc-simd/ 'SIMD and other
techniques for fast numerical programming with gcc'.
