Thank you very much for your reply. 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?
