The structure of speech (problems) envir interferes with speech signal visual signals = distractions variability of speech signal ex the speakers voice , rate they are talking and phonetic context. Prosodic factors prosodic factors: ex stress, intonation and rate. General term that refers to aspects of an utterance"s sound that are not specific to the words themselves. Influence overall meaning of utterance stress: emphasis given to syllables in sentence intonation: use of pitch to signify diff meaning. Pitch pattern in sentence = intonational contour. Voicing glottis: opening between vocal cords voiced: airstream forces its way through glottis if cords are tgthr -> which vibrate. Acoustic phonetics can encode 25 30 phonetic segments per sec. Parallel transmission parallel transmission: diff phonemes of same syllable are encoded into the speech signal simultaneously - no sharp physical break between adjacent sounds in a syllable.
