3. Watch this video https://www.youtube.com/watch?v=IGQmdoK_ZfY. Explain what happened? and What does it teach us about perception?

4. Explain how differentiating between /r/ and /l/ and babies classifying vowels relate to speech perception and How does that relate to learning a second language?

5. Let’s make some spectrograms! First, let’s draw what you would expect the words “asa” and “aza” (“a” as in “pot”). So, draw what a spectrogram might look like for “asa” and “aza” and indicate where the voicing bar is or is not.

6. What would you expect to see for vowels vs. diphthongs? Draw your guess.

7. Draw a voiceless stop and a voiced stop on a spectrogram, and label the 3 features.

8. How might voice-onset time look for the consonants in “apa” and “aba”?

9. Draw a fricative.

10. Are fricatives more periodic or aperiodic? Why?
