I saw on the NASA web that somebody asked 'is this galaxy picture from Hubble as real or it is artistic concept?' . With the powerful image processing you can sharpen the pictures to a reasonable degree. At the other hand , the speech processing is the advanced field that signal processing can shows his powerful concepts there. Can you please let me know which advanced speech processing concepts you can address on Mathematica?
