Questions 1

Design and perform a small experiment to investigate the following question:

"A man and a woman pronounce the same voiced phoneme. How are the formants of the phoneme pronounced by the man different from the formants of the phoneme pronounced by the woman?"

Describe your experiment and discuss your results.

Question 2

"That's one small step for a man, one giant leap for mankind", was the phrase Purdue alumnus Neil Armstrong planned to say as he stepped foot on the moon during the Apollo 11 mission. However, a careful listening of the recording indicates that the phrase he actually uttered is "That's one small step for man, one giant leap for mankind", skipping the "a" before "man" and thus creating a tautology.

Listen for yourself at either of these links:

Using any appropriate DSP technique, investigate whether Neil Armstrong did say "a" before the word "man".
