speech sound acoustics

speech sound acoustics   Order Description   Instructions: 1. Describe the acoustic properties of /r/ and /l/ AND contrast them. 2. Describe categorical perception versus continuous perception AND contrast them 3. How can the visual representation of a spectrogram, waveform, and spectrum be used to describe and understand the acoustic characteristics of speech sounds? how can one identify vowels vs. diphthongs vs. glides. sonorant vs obstruents, stops vs fricatives vs affricates. liquids vs nasals vs vowels by looking at the spectrogram? How does each of these characteristics reflect on a waveform or spectrum? 4. compare and contrast assimilation vs coarticulation. how can spectrograms and waveforms be used to understand this differences? 5. describe each prosodic feature; intonation, stress and duration, juncture. How can one understand the characteristics of intonation, stress, and juncture using spectrograms and waveforms?
