Record a sound file of yourself saying your full name using Praat. Display the spectrogram. Create an orthographic tier. Segment and label each phoneme from the spectrogram using the IPA system.
The files win1.wav and win2.wav have the same words, "Anna will win Manny", but uttered differently. Describe the acoustic differences that might account for the different meanings (e.g., variations in pitch and intensity). (One paragraph)
The file thermometer.wav contains a declarative contour. Modify its pitch and duration to produce two contours that convey different meanings (yes/no question, incredulity, stress on a different word, etc. —use your imagination!).
Submit the resulting .wav files.
Hint:
a) Open the file
thermometer.wav.
b) Create a Manipulation object, and Edit it.
c) Select Pitch → Stylize Pitch (2 st).
d) Have fun modifying the pitch and the duration tiers!
You may hand in this problem (and only this one!) either in hard copy or in electronic form in the lecture of the due date.
The following waveform and spectrogram correspond to a short phrase elicited fluently and in a neutral tone by a male native speaker of American English.
a) Identify the phone sequence in this utterance using IPA symbols as well as
you can.
b) Which of the following phrases does this waveform and spectrogram correspond
to?
1. "Harry Potter can't fly."
2. "Columbia University."
3. "Anna likes New York."
4. "Where did Tweety go?"
5. "Amelia made the jam."
Hint: Record yourself saying these phrases, and compare their waveforms and spectrograms with the one shown above.
