I realize that this might not be the most well-formulated question, but I figured I'd throw it out there as an open-ended discussion that could turn up some interesting input.
I'm relatively new to speech processing, and came across the statement "invariance to transformation is important in many speech engineering tasks" in a paper I'm reading.
I was wondering if anyone could provide any specific examples that could illustrate what exactly this means. The word transformation to me is a bit ambiguous, maybe because I'm relatively new to this particular field, but I was hoping that this statement is a little more obvious to someone else out there who is more familiar with the field.
