The vowels e and a : e seems to be produced at the front of the oral cavity, a seems to be produced in the back. Voicing: zzzz produces vibration, when there is vibration, we say it"s voiced (no vibration voiceless) We hear a blur" of words, yet can reproduce that blur into sounds that are comprehensible. Parallel transmission: some of the information is encoded simultaneously. If you remove a" from ba", you don"t get b", but instead a click sound", because some of the b" is in the a". Context-conditioned variation: when comparing dig to dug, the letter following d will change the appearance of it, depending on what it is. This occurs to produce the language quickly. Explaining the variability in how we produce sounds. Wanted to assess if they can discriminate sounds. Found that the erp"s done at 36 hours were able to predict 80% accuracy on whether the children will be normal, poor, or dyslexic readers.
