“…These patterns of impairment in the amplitude of the murmur are consistent with a deficit in laryngeal control. Similar conclusions have been made in analyses of voicing in fricative consonants (Kurowski et al, 2003) where Broca's aphasics were unable to sustain normal amplitude levels of voicing during the frication noise, and in analyses of prosody and tone (Ryalls, 1982;Kent and Rosenbek, 1983;Cooper et al, 1984;Harmes et al, 1984;Packard, 1986;and Gandour, Potisuk et al, 1992), where Broca's aphasics showed abnormal pitch modulation.…”

“…These deficits emerge in the production of stop consonants where there is weaker high frequency energy (Shinn and Blumstein, 1983), in the production of fricative consonants where there is a weak energy throughout the frequency spectrum in the fricative noise (Harmes, Daniloff, Hoffman, Lewis, Kramer, and Absher, 1984), and a weaker amplitude of voicing for voiced fricatives resulting in greater overlap in the amplitudes of glottal excitation for voiced and voiceless fricatives (Kurowski, Hazen, and Blumstein, 2003). Deficits in the production of prosody also occur and are characterized by restrictions in fundamental frequency range (Cooper, Soares, Nicol, Michelow, and Goloskie, 1984;Ryalls, 1982;Kent and Rosenbek, 1983;Harmes et al, 1984), and a reduced proficiency in implementing lexical tone (Packard, 1986;Gandour. Ponglorpisit, Khunadorn, Dechongkit, Boongird, Boonklam, and Potisuk, 1992).…”

Nasal consonant production in Broca’s and Wernicke’s aphasics: Speech deficits and neuroanatomical correlates

et al. 2007

The present study investigated the articulatory implementation deficits of Broca's and Wernicke's aphasics and their potential neuroanatomical correlates. Five Broca's aphasics, two Wernicke's aphasics, and four age-matched normal speakers produced consonant-vowel-(consonant) real word tokens consisting of [m, n] followed by [i, e, a, o, u]. Three acoustic measures were analyzed corresponding to different properties of articulatory implementation: murmur duration (a measure of timing), amplitude of the first harmonic at consonantal release (a measure of articulatory coordination), and murmur amplitude over time (a measure of laryngeal control). Results showed that Broca's aphasics displayed impairments in all of these parameters, whereas Wernicke's aphasics only exhibited greater variability in the production of two of the parameters. The lesion extent data showed that damage in either Broca's area or the insula cortex was not predictive of the severity of the speech output impairment. Instead, lesions in the upper and lower motor face areas and the supplementary motor area resulted in the most severe implementation impairments. For the Wernicke's aphasics, the posterior areas (superior marginal gyrus, parietal, and sensory) appear to be involved in the retrieval and encoding of lexical forms for speech production, resulting in increased variability in speech production.

“…Similar to the findings for normal talkers by McFarland & Baum (1995), no such F1 differences were observed for [u]. Lexical tone production impairment has been reported in monolingual speakers of tone languages with left-hemisphere brain damage, including speakers of Thai (e.g., Gandour & Ponglorpisit, 1990;Gandour, Ponglorpisit, & Dardarananda, 1992;Gandour, Ponglorpisit, Khunadorn, Dechongkit, Boongrid, Boonklam, & Potisuk, 1992), Mandarin (Packard, 1986(Packard, , 1992, Cantonese (Yiu & Fok, 1995), and Toisanese (Eng-Huie, 1994). Only one study has examined tone production in an individual who speaks more than one tone language, namely, Mandarin, Cantonese, and a Jiangxi dialect (Naeser & Chan, 1980).…”

“…In recent years, a number of neurophysiological studies in regard to pitch processing have emerged, mainly with lesion, dichotic listening and functional neuroimaging techniques (Gandour et al, 1992;Klein et al, 2001;Van Lancker and Fromkin, 1973;Wang et al, 2003). However, due to the low temporal resolution of these techniques, event-related potentials (ERPs), a high temporal resolution measure was introduced to pitch processing, offering more precise temporal information of online processing.…”

Online processing of tone and intonation in Mandarin: Evidence from ERPs

2016

a b s t r a c tEvent-related potentials (ERPs) were used to investigate the online processing of tone and intonation in Mandarin at the attentive stage. We examined the behavioral and electrophysiological responses of native Mandarin listeners to Mandarin sentences, which contrast in final tones (rising Tone2 or falling Tone4) and intonations (Question or Statement). A clear P300 effect was observed for question-statement contrast in sentences ending with Tone4, but no ERP effect was found for question-statement contrast in sentences ending with Tone2. Our results provide ERP evidence for the interaction of tone and intonation in Mandarin, confirming the findings with behavioral metalinguistic data that native Mandarin listeners can distinguish between question intonation and statement intonation when the intonation is associated with a final Tone4, but fail to do so when the intonation is associated with a final Tone2. Our study extended the understanding of online processing of tone and intonation (1) from the pre-attentive stage to the attentive stage and (2) within a larger domain (i.e. multi-word utterances) than a single word utterance.
