LING 7800-005: LSA Summer Institute 20112
Homework 2: Background in Prosody/Acoustics
Due in 2 parts:
Part I due before class on July 12
Part II will be a lab assignment to be given out and started in class,
with your results emailed to us together with Part III.
Part I: Praat practice (due before class on Tue July 12),
- Download Praat onto a laptop that you can bring to class. (If that's not possible, use another computer, and you will have to share a laptop with someone on Tuesday).
- Read the very brief tutorial here, and look
at the homepage: http://www.fon.hum.uva.nl/praat/
- Additional PRAAT resources:
- » http://www.helsinki.
- » http://uk.groups.yahoo.com/group/praat-users/
- » http://www.linguistics.ucla.edu/faciliti/facilities/acoustic/praat.html
- Record yourself in Praat saying the following two sentences:
- "That chapter is definitely too long"
- "That cockroach is totally disgusting!"
- For each of the two sentences, mail me (before class) the following 6 pieces of information:
- The average pitch of the whole sentence in Hz
- The maximum pitch for the whole utterance in Hz
- The minimum pitch for the whole utterance in Hz
- The maximum intensity for the whole utterance in dB
- The minimum intensity for the whole utterance in dB
- Your rate of speech in words per second for the utterance.
- Write one more sentence based on these numbers describing the intonational/prosodic difference betweeen the two sentences
and saying something about the cause.
Part II: Smiling speech (we will start this in class on Tue July 12 but you should finish at home and hand in the writeup together with Part III)
- Bring your laptop to class with Praat installed
- Get a partner; you can use both your laptops or share one.
- We will start this in class but you should finish at home
- Smiling speech:
Record yourself saying the sentence This sentence might be a smiling sentence
in two ways: smiling and not smiling. Try for a genuine smile; use your partner to make sure you get a good example.
- Compare the two sentences on F0, F1, F2, and energy. Discuss any patterns you see.
- You can, if you want, read one of these papers:
- Write up one pgraph with your numbers and the discussion. If you want, in your writeup you can compare to the Drahota or Robson papers.
Part III: Sarcasm
Read this paper:
Record yourself saying the sentence Yeah, right!
in two ways: sarcastic and not sarcastic. Try for genuine sarcasm; use your partner to make sure you get a good example
and the two utterances are distinct.
- Compare the two sentences on prosodic features (pitch, energy, duration). Discuss any patterns you see.
- Write up one pgraph with your numbers and the discussion. In your writeup, make sure you compare to the Tepperman et al. paper
