Subject: Re: child's play From: RealTime <mandra(at)PEABODY.JHU.EDU> Date: Tue, 27 May 1997 10:16:04 -0400Aren't score following programs just pattern recognition systems, with the score being essentially a database of patterns. The main difference would be the transposition, but if it searched all transpositions of the pattern, I would imagine that it would be able to follow along. A better question (or perhaps more compelling?) would be : " if a person can't really whistle, but instead sort of 'shapes/filters' white noise with his mouth, teeth and tongue, and a child could recognize the melody, could the computer easily see beyond the noise to the pitch contour and subsequently to the melody itself?" chris chris mandra ///// Deus Ex Machina x x * http://www.peabody.jhu.edu/~mandra/ <-> http://www.charm.net/~metamuse On Tue, 27 May 1997, Robert Zatorre wrote: > Dear List > Not to change the topic from all the exchanges about oscillating networks > and all, but here's a lighter question (perhaps), especially for you > modelling/AI types.
