Problem
1. Write a program for the detection of voiced and unvoiced segments using the AMDF function. Test your algorithm on the test . snd sound file.
2. Select a voiced segment from the test . raw file. Find the fourth-, sixth-, and tenthorder LPC filters for this segment using the Levinson-Durbin algorithm. For each of the filters, find the multipulse sequence that results in the closest approximation to the voiced signal.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
