“…In that view, assimilation takes place in order to make the speakerÕs job easier, but only if the communicative situation allows it. This reflects the ideas laid down in the H&H theory (Lindblom, 1990). At faster rates, however, unassimilated pronunciations were preferred (Quene and Krull, 1999).…”

“…But in normal everyday communication, a locally increased rate can still be functional, in that slower speech rate generally signals new and important information, and faster speech rate signals given or redundant information (Lindblom, 1990). When speakers speak faster during more redundant words, it seems rather unlikely that this should in the end be problematic for listeners.…”

Word perception in fast speech: artificially time-compressed vs. naturally produced fast speech

Natural fast speech differs from normal-rate speech with respect to its temporal pattern. Previous results showed that word intelligibility of heavily artificially time-compressed speech could not be improved by making its temporal pattern more similar to that of natural fast speech. This might have been due to the extrapolation of timing rules for natural fast speech to rates that are much faster than can be attained by human speakers. The present study investigates whether, at a speech rate that human speakers can attain, artificially time-compressed speech is easier to process if its timing pattern is similar to that of naturally produced fast speech. Our first experiment suggests, however, that word processing speed was slowed down, relative to linear compression. In a second experiment, word processing of artificially time-compressed speech was compared with processing of naturally produced fast speech. Even when naturally produced fast speech is perfectly intelligible, its less careful articulation, combined with the changed timing pattern, slows down processing, relative to linearly time-compressed speech. Furthermore, listeners preferred artificially time-compressed speech over naturally produced fast speech. These results suggest that linearly time-compressed speech has both a temporal and a segmental advantage over natural fast speech.

“…The Acoustic Invariance Theory (Stevens & Blumstein, 1978;Blumstein & Stevens, 1979), the Quantal Theory of Speech (Stevens, 1972(Stevens, , 1989, and the Adaptive Variability Theory (Lindblom, 1988(Lindblom, , 1990 basically defend the idea that the motor goals are in the auditory perception domain. Thus, in the language of motor control these theories favor extrinsic motor goals.…”

This paper presents a comparative conceptual review of speech and limb motor control.Speech is essentially cognitive in nature and constrained by the rules of language, while limb movement is often oriented to physical objects. We discuss the issue of intrinsic vs. extrinsic variables underlying the representations of motor goals as well as whether motor goals specify terminal postures or entire trajectories. Timing and coordination is recognized as an area of strong interchange between the two domains. Although coordination among different motor acts within a sequence and co-articulation are central to speech motor control, they have received only limited attention in manipulatory movements. The biomechanics of speech production is characterized by the presence of soft tissue, a variable number of degrees of freedom, and the challenges of high rates of production, while limb movements deal more typically with inertial constraints from manipulated objects. This comparative review thus leads us to identify many strands of thinking that are shared across the two domains, but also points us to issues on which approaches in the two domains differ. We conclude that conceptual interchange between the fields of limb and speech motor control has been useful in the past and promises continued benefit.

“…Quite a large body of research has shown that syllable stress and pitch accent strongly affect vowel duration and the level of vowel reduction (eg., Fourakis, 1991;Koopmans-Van Beinum, 1980;Lindblom, 1990;Van Bergem, 1995;Pols, 1990, 1992;Wang, 1997) and consonant reduction (de Jong et al, 1993;de Jong, 1995;Farnetani, 1995;Pols, 1996, 1999a). An archetypal example of reduction is that of vowel realizations becoming more like a schwa in unstressed syllables (eg., Koopmans-Van Beinum, 1980;Lindblom, 1990;Van Bergem, 1995). It has been shown that (lexical) syllable stress also affects the overall spectral balance of vowels (ie., spectral slope, Sluijter, 1995a, b;Sluijter and Van Heuven, 1996;Van Son and Pols, 1999a;cf., spectral tilt in Tabain, 2003).…”

Duration and spectral balance of intervocalic consonants: A case for efficient communication

The prosodic structure of speech and the redundancy of words can significantly strengthen or weaken segmental articulation. This paper investigates the acoustic effects of lexical stress, intra-word location, and predictability on sentence internal intervocalic consonants from accented words, using meaningful reading materials from 4157 sentences read by two American English speakers. Consonant duration and spectral balance in such reading materials show reduction in unstressed consonants and in consonants occurring later in the word (Initial vs. Medial vs. Final). Coronal consonants behaved distinctly, which was interpreted as a shift from full to flap or tap articulation in a subset of the phoneme realizations. This shift in articulation, and part of the consonant specific acoustic variation, could be linked to the frequency distribution of consonant classes over the investigated conditions. A higher frequency of occurrence of a consonant class in our corpus and a CELEX word-list was associated with shorter durations and differences in spectral balance that would increase the communicative efficiency of speech.
