Regarding the perception of regional speech and the salience of language variants it is to as-sume, that they are being influenced by individual features of the specific speaker/listener. However, most recent studies dealing with the salience of language phenomena neglect factors like, for example, language awareness or the profession of speakers. This article focuses on the correlation between speech perception, speech production and individual characteristics of speakers like the metalinguistic knowledge they have. It presents selected results of a study dealing with the perception and production of regional speech in Bremen and Hamburg and discusses different types of speaker/listener profiles.

Anatomical Information

Surface electromyograms were recorded from 13 locations on the tongue of one subject during production of 17 different types of [p]-vowel-[p] monosyllables. Results were considered together with X-ray data on tongue action, and anatomical information on tongue musculature, in an attempt to describe the action of tongue muscles during vowel production. It proved possible in most cases to assign muscles, with some certainty, to the major features of myographic activity, and to indicate what function the muscle was serving. The results have particular relevance to theories of sequential speech production, and indirectly, theories of speech perception, as they provide a basis for description of how coarticulation of vowels with consonants involving the tongue takes place.

The Individual

In our previous studies we supported the claim that the motor theory is modulated by task load. Motoric participation in phonological processing increases from speech perception to speech production, with the endpoints of the dorsal stream having changing and complementary weightings for processing: the left inferior frontal gyrus (LIFG) being increasingly relevant and the left superior temporal gyrus (LSTG) being decreasingly relevant. Our previous results for neurostimulation of the LIFG support this model. In this study we investigated whether our claim that the motor theory is modulated by task load holds in (frontal) aphasia. Person(s) with aphasia (PWA) after stroke typically have damage on brain areas responsible for phonological processing. They may present variable patterns of recovery and, consequently, variable strategies of phonological processing. Here these strategies were investigated in two PWA with simultaneous fMRI and tDCS of the LIFG during speech perception and speech production tasks. Anodal tDCS excitation and cathodal tDCS inhibition should increase with the relevance of the target for the task. Cathodal tDCS over a target of low relevance could also induce compensation by the remaining nodes. Responses of PWA to tDCS would further depend on their pattern of recovery. Responses would depend on the responsiveness of the perilesional area, and could be weaker than in controls due to an overall hypoactivation of the cortex. Results suggest that the analysis of motor codes for articulation during phonological processing remains in frontal aphasia and that tDCS is a promising diagnostic tool to investigate the individual processing strategies.

PurposeTo determine whether preschool-age children with cochlear implants have age-appropriate phonological awareness and print knowledge and to examine the relationships of these skills with related speech and language abilities.MethodThe sample comprised 24 children with cochlear implants (CIs) and 23 peers with normal hearing (NH), ages 36 to 60 months. Children's print knowledge, phonological awareness, language, speech production, and speech perception abilities were assessed.ResultsFor phonological awareness, the CI group's mean score fell within one standard deviation of the Test of Preschool Early Literacy's (Lonigan, Wagner, Torgesen, & Rashotte, 2007) normative sample mean but was more than one standard deviation below the NH group mean. The CI group's performance did not differ significantly from that of the NH group for print knowledge. For the CI group, phonological awareness and print knowledge were significantly correlated with language, speech production, and speech perception. Together these predictor variables accounted for 34% of variance in the CI group's phonological awareness but no significant variance in their print knowledge.ConclusionsChildren with CIs have the potential to develop age-appropriate early literacy skills by preschool age but are likely to lag behind their NH peers in phonological awareness. Intervention programs serving these children should target these skills with instruction and by facilitating speech and language development.

Speech Perception And Production

The objective of this experiment was to quantify and localize the effects of wearing the nuclear, biological, and chemical (NBC) M40 protective mask and hood on speech production and perception. A designated speaker's vocalizations of 192 monosyllables while wearing an M40 mask with hood were digitized and used as speech stimuli. Another set of speech stimuli was produced by recording the same individual's vocalizing the same monosyllables without the mask and hood. Participants listened to one set of stimuli during two sessions, one session while wearing an M40 mask with hood and another session without the mask and hood. The results showed that wearing the mask with hood gave most detrimental effects on the sustention dimension acoustically for both speech perception and production. The results also showed that wearing it was detrimental on vocalizing and listening to fricatives and unvoiced-stops. These results may be due to the muffling effect of the voicemitter in speech production and the filtering effects of the voicemitter and the hood material on high frequency components during both speech production and perception. This information will be useful for designing better masks and hoods. This methodology also can be used to evaluate other speech communication systems.

Abstract Spoken language, both perception and production, is thought to be facilitated by an ensemble of predictive mechanisms. We obtain intracranial recordings in 37 patients using depth probes implanted along the anteroposterior extent of the supratemporal plane during rhythm listening, speech perception, and speech production. These reveal two predictive mechanisms in early auditory cortex with distinct anatomical and functional characteristics. The first, localized to bilateral Heschl’s gyri and indexed by low-frequency phase, predicts the timing of acoustic events. The second, localized to planum temporale only in language-dominant cortex and indexed by high-gamma power, shows a transient response to acoustic stimuli that is uniquely suppressed during speech production. Chronometric stimulation of Heschl’s gyrus selectively disrupts speech perception, while stimulation of planum temporale selectively disrupts speech production. This work illuminates the fundamental acoustic infrastructure—both architecture and function—for spoken language, grounding cognitive models of speech perception and production in human neurobiology.

Nasal Emission

There are several different types of nasal emission that can occur during speech due to either velopharyngeal dysfunction or abnormal articulation in the pharynx. Nasal emission can be inaudible or very loud and distracting, depending on the size of the velopharyngeal opening and the physics of the flow. Nasal emission can be obligatory and/or compensatory (due to abnormal structure) or it can be caused by a misarticulation that results in a substitution of a pharyngeal sound for an oral sound, despite normal velopharyngeal structure. Nasal emission can occur on all pressure-sensitive phonemes or it can be phoneme-specific. Although it is generally recognized that the loud and distracting form of nasal emission (called nasal turbulence or nasal rustle) is due to a small velopharyngeal opening, the causality of the distracted sound is debated. This article provides a brief review of the types of nasal emission, the terms used to describe it, and the potential causes. This article also stresses the need for further research to clarify the causality of the sound generated by a small velopharyngeal opening.
