One reason why the study of speech production addresses the subsystems separately, and in sequential order, is - ANSWER-this approach simplifies a large and complex topic Evidence to support the view that acoustic targets are the main control variables for speech comes from - ANSWER-distortions in the speech of people with hearing impairment What is one of the theoretical problems associated with the idea of motor programs? - ANSWER-many thousands of programs would need to be stored for all the movement we make A coordinative structure is - ANSWER-a group of muscles that works together to achieve an articulatory goal The spatiotemporal index is designed to measure - ANSWER-the consistency of movement across multiple repetitions of an utterance The most basic unit of analysis for speech motor control is - ANSWER-scientists do not agree one single unit of measurement for control The notion that rhythmic jaw movements underlie the syllabic production of speech is part of the - ANSWER-frame theory Motor equivalence in speech motor control means that - ANSWER-repeating an utterance more than once may involve subtle differences in articulator movements The following are examples of perturbation methods used in speech research - ANSWER-an artificial palate delayed auditory feedback an unanticipated tap on the lip or jaw Clear speech typically includes - ANSWER-increased fundamental frequency variability The speech signal is - ANSWER-neither invariant nor linear When a listener simplifies the processing of the speech signal to smooth out superfluous variability, it is called - ANSWER-perceptual normalization One type of quantal perception that occurs as we listen to speech is called - ANSWER-categorical perception In duplex perception - ANSWER-syllable components are presented separately, but simultaneously, to each ear In the McGurk effect - ANSWER-the place and/or manner of articulation is perceived to change Top-down processing in the perception of speech involves - ANSWER-using contextual, linguistic, and cognitive cues Which speech perception theory has been criticized as being so vague that it is more of a philosophy than a theory or model? - ANSWER-motor theory Perceptual magnets - ANSWER-enhance differences between distinct phonemes The cohort theory is based on - ANSWER-similarity of acoustic features of the beginning of words Research with infants has shown that - ANSWER-dominant language exposure gradually decreases discrimination of non-native speech features During the closure of a voiced stop, vocal fold vibration may cease because - ANSWER-supraglottal pressure rises to equal subglottal pressure For a stop to be perceived as voiceless, the VOT would generally be - ANSWER-40 to 100 ms During the transition from a stop to a vowel - ANSWER-F1 rises Relative to fricatives like /f/, sibilants are produced with - ANSWER-a larger anterior resonating space, a greater degree of constriction, stronger, higher-frequency energy The likely reason why vowels are shorter before a voiceless stop or fricative is - ANSWER-anticipatory coarticulation ends phonation ahead of the voiceless sound When an affricate is produced - ANSWER-the two sounds must share the same place of articulation and voicing characterist
