This has a really interesting discussion of "machine listening" starting about 13 minutes in.
I agree with his recommendation of Don Reinertsen's _Managing the Design Factory_. (I assume that's the book he recommended.) I read it last year and it had a strong effect on me.
The book linked from the show is The Principle of Product Development Flow: Second Generation Lean Product Development.
The recent review at http://www.amazon.co.uk/review/R2I26D6N27OE91/ indicates that "Managing the Design Factory" can be seen as more of an introduction, whereas the latter book has more detail.
