Document Summary

Assimilation: segments adopt features from neighboring sounds. Example: if you have two vowels in a row, you add an r in the middle. They create phonetic patterns that conform to phonatatics (probabilistic sound patterns). Vowel reduction: vowel quality changes (becomes centralized) You can change the stress pattern, and therefore change the vowels. Prosody has a lot of things that go together within it. There are a lot of different ways in which we change the production of speech in order to stress a part of the sentence. Pitch is how high or low a note sounds. Vocal pitch carries a wealth of information: age, emotional state, sex, syntactic structure, stress, pathology, semantic meanings, etc. When we stress a word, we raise the pitch. It is hard to hear out the fact that a stressed syllable has a high pitch, we just think it is stressed.
