“…Therefore, all time intervals exceeding the eyeblink threshold (30 nAm) were marked and the MEG signal set to zero in all channels for the duration of these intervals. This procedure, also applied in previous studies (Hertrich et al, 2012;Hertrich et al, 2013), led to a loss of about 5% of the total of MEG data.…”

“…Cross-correlation analysis was conducted in order to obtain a measure of early phase-locked auditory brain responses as described in Hertrich et al (2012). This approach has several advantages in comparison to a conventional evaluation of evoked neural activity.…”

“…Previous studies had revealed that these phase-locked brain responses resemble auditory evoked activity and, furthermore, are related to speech intelligibility and attention control (Ahissar et al, 2001;Deng & Srinivasan, 2010;Ding & Simon, 2013;Drullman, Festen, & Plomp, 1994;Elliott & Theunissen, 2009;Golumbic et al, 2013;Hertrich et al, 2013;Noordhoek & Drullman, 1997). The major sources of electrophysiological activity phase-locked to modulation frequencies of the speech envelope have been assigned to the central-auditory system (Hertrich et al, 2012;Hertrich et al, 2013;Korzyukov et al, 2007;Luo & Poeppel, 2007). Furthermore, functional magnetic resonance imaging (fMRI) studies have been able to document significant effects of linguistic or visual context on auditory phonetic processing (Guediche, Salvata, & Blumstein, 2013;Skipper, 2014).…”

“…Against this background, the present study addresses the question of whether early auditorily evoked MEG activity phase-locked to syllable onsets during the processing of PSPs is modulated by discourse coherence depending upon preceding context sentences. The syllable onset signal -derived in the present study from the speech envelope by simple computational operations (Hertrich et al, 2012) -can be taken as a marker for the phonetic ''sonority rise'' toward the vowel nuclei, a feature relevant for the alignment of segmental and suprasegmental information (Arvaniti, Ladd, & Mennen, 1998;Gick, Campbell, Oh, & Tamburri-Watt, 2006;Ladd, Dan, Hanneke, & Astrid, 1999;Prieto & Torreira, 2007). Thus, synchronization of brain activity to syllable onsets might serve as a neuronal attention-driven mechanism to capture important speech information.…”

“…In case of the semantic/pragmatic research question of the present study, such an approach is not feasible because the processing of presupposed material may differ across repetitions -depending upon whether an identical utterance has been received before or not. As an alternative, the present experiment relied upon a cross-correlation technique for a quantitative evaluation of MEG responses to syllable onset-related aspects of amplitude modulations of the speech signal (Abrams, Nicol, Zecker, & Kraus, 2008Aiken & Picton, 2008;Hertrich, Dietrich, & Ackermann, 2013;Hertrich, Dietrich, Trouvain, Moos, & Ackermann, 2012). This technique can be applied to continuous stretches of speech and allows for a condensation of speech-evoked brain activity into a single compact measure.…”

Context‐dependent role of selective attention for change detection in multi‐speaker scenes

Disappearance of a voice or other sound source may often go unnoticed when the auditory scene is crowded. We explored the role of selective attention for this change deafness with magnetoencephalography in multi-speaker scenes. Each scene was presented two times in direct succession, and one target speaker was frequently omitted in Scene 2. When listeners were previously cued to the target speaker, activity in auditory cortex time locked to the target speaker's sound envelope was selectively enhanced in Scene 1, as was determined by a cross-correlation analysis. Moreover, the response was stronger for hit trials than for miss trials, confirming that selective attention played a role for subsequent change detection. If selective attention to the streams where the change occurred was generally required for successful change detection, neural enhancement of this stream would also be expected without cue in hit compared to miss trials. However, when listeners were not previously cued to the target, no enhanced activity for the target speaker was observed for hit trials, and there was no significant difference between hit and miss trials. These results, first, confirm a role for attention in change detection for situations where the target source is known. Second, they suggest that the omission of a speaker, or more generally an auditory stream, can alternatively be detected without selective attentional enhancement of the target stream. Several models and strategies could be envisaged for change detection in this case, including global comparison of the subsequent scenes.

Neurophonetics aims at the elucidation of the brain mechanisms underlying speech communication in our species. Clinical observations in patients with speech impairments following cerebral disorders provided the initial vantage point of this research area and indicated distinct functional-neuroanatomic systems to support human speaking and listening. Subsequent approaches-considering speech production a motor skill-investigated vocal tract movements associated with spoken language by means of kinematic and electromyographic techniques-allowing, among other things, for the evaluation of computational models suggesting elementary phonological gestures or a mental syllabary as basic units of speech motor control. As concerns speech perception, the working characteristics of auditory processing were first investigated based upon psychoacoustic techniques such as dichotic listening and categorical perception designs. More recently, functional hemodynamic neuroimaging and electrophysiological methods opened the door to the delineation of multiple stages of central auditory processing related to signal detection, classification, sensory memory processes, and, finally, lexical access. Beyond the control mechanisms in a stricter sense, both speech articulation and auditory processing represent examples of 'grounded cognition'. For example, both domains cannot be restricted to text-to-speech translation processes, but are intimately interwoven with neuropsychological aspects of speech prosody, including the vocal expression of affects and the actual performance of speech acts, transforming propositional messages to 'real' utterances. Furthermore, during language acquisition, the periphery of language-i.e., hearing and speaking behavior-plays a dominant role for the construction of a language-specific mental lexicon as well as language-specific action plans for the production of a speech message.
