“…In contrast to the current findings, Wong, Uppunda, Parrish, and Dhar (2008) observed that the STG was more active during listening to speech in noise relative to listening to speech in quiet. However, in line with the relation between RSpan and the STG activation as observed in the current study, they suggested a role of the STG in a phonological working memory network.…”

Text cues facilitate sentence perception when they are semantically related to the speech (Zekveld et al., 2011a). In this study, semantically related and unrelated cues preceding sentences evoked more activation in middle temporal gyrus (MTG) and inferior frontal gyrus (IFG) than non-word cues, regardless of acoustic quality (speech in noise or speech in quiet).Larger verbal working memory (WM) capacity (reading span) was associated with greater intelligibility benefit obtained from related cues, with less speech-related activation in the left superior temporal gyrus and left anterior IFG, and with more activation in right medial frontal cortex for related versus unrelated cues. Better ability to comprehend masked text was associated with greater ability to disregard unrelated cues, and with more activation in left angular gyrus (AG). We conclude that individual differences in cognitive abilities are related to activation in a speech-sensitive network including left MTG, IFG and AG during cued speech perception.

“…Studies investigating the effect of external distortions on speech processing generally do so use added background noise (Davis & Johnsrude, 2003;Scott, Rosen, Wickham, & Wise, 2004;Wong et al, 2008). Wong et al presented words in background noise (multi-talker babble) in various signal-to-noise (SNRs) in decibel (dB) ratios (quiet, +20 dB, −5 dB) and reported an increase in the Blood-Oxygenated Level Dependent (BOLD) response for decreasing SNRs across a wide network of cortical regions, involving Superior Temporal Gyrus (STG) including Heschl's Gyrus (HG) bilaterally, left Inferior Frontal Gyrus (IFG) and the Frontal Operculum (FO).…”

“…Some distortions are related to properties of the channel between conversation partners (external distortions), such as background noise, interruptions or signal degradation due to speaking over a telephone (Davis & Johnsrude, 2003;Wong, Uppanda, Parrish, & Dhar, 2008). Other distortions are related to the way in which the speaker produces utterances (speakerrelated distortions), e.g., those due to anatomical and physiological differences between speakers, differences in speech rate, accent differences related to speakers' regional background, and differences related to speech style such as mumbling, reading aloud versus spontaneous speech (Adank, Evans, Stuart-Smith, & Scott, 2009;Dupoux & Green, 1997;Floccia, Goslin, Girard, & Konopczynski, 2006;Peterson & Barney, 1952).…”

Neural dissociation in processing noise and accent in spoken language comprehension

a b s t r a c tWe investigated how two distortions of the speech signal -added background noise and speech in an unfamiliar accent -affect comprehension of speech using functional Magnetic Resonance Imaging (fMRI). Listeners performed a speeded sentence verification task for speech in quiet in Standard Dutch, in Standard Dutch with added background noise and for speech in an unfamiliar accent of Dutch. The behavioural results showed slower responses for both types of distortion compared to clear speech, and no difference between the two distortions. The neuroimaging results showed that, compared to clear speech, processing noise resulted in more activity bilaterally in Inferior Frontal Gyrus, Frontal Operculum, while processing accented speech recruited an area in left Superior Temporal Gyrus/Sulcus. It is concluded that the neural bases for processing different distortions of the speech signal dissociate. It is suggested that current models of the cortical organisation of speech are updated to specifically associate bilateral inferior frontal areas with processing external distortions (e.g., background noise) and left temporal areas with speaker-related distortions (e.g., accents).Crown

“…It has been associated with numerous functions such as auditives processing (Humphries et al 2001), learning and memory (Schiltz et al 1973), social cognition (Ingrid et al 2007), and language processing (Hermann & Wyler 1988). STG (BA 22) plays the role in auditives language reception and processing (Wong et al 2008). From Table 1, L-STG and L-TP show extended and higher activation as compared to R-STG and R-TP both during AIQ and AIN.…”

“…Scott et al (2004) suggested that there is an engagement of perception and cognitive networks during listening to speech in noisy condition. In terms of the brain functional anatomy, the superior temporal gyrus (STG) plays a central role in the perception of speech (Wong et al 2008) and non-speech stimuli (Hall et al 2002).…”

gyrus (L-MFG), right superior frontal gyrus (R-SFG), right superior orbital gyrus (R-SOG) and bilateral insula were more active in quiet as compared to in noise while the left middle cingulate cortex (L-MCC), left amygdala (L-AMG), right temporal pole (R-TP) and left cerebellum (L-CER) were more active in noise as compared to in quiet. The t value for most of the activated regions was found to be inversely proportional to the neural effi cacy. Signifi cant (p < 0.05) negative relationship between t value and neural effi cacy were found for R-STG and bilateral cerebellum during AIQ

Cortical Mechanisms of Speech Perception in Noise

Abstract: We found cortical task-independent and noise-dependent effects concerning speech perception in noise involving bilateral mSTG and left pSTG. These results likely reflect demands in acoustic analysis, auditory-motor integration, and phonological memory, as well as auditory attention.
