Transient and sustained cortical activity elicited by connected speech of varying intelligibility

Hannu Tiitinen, Ismo Miettinen, Paavo Alku, Patrick J C May
2012 BMC Neuroscience  
The intervening exposure to undistorted versions of sentences rendered the initially unintelligible, distorted sentences intelligible, as evidenced by an increase from 30% to 80% in the proportion of sentences  ...  In the time range of auditory P2m response (>200 ms), auditory cortex as well as regions anterior and posterior to this area generated a stronger response to sentences which were intelligible than unintelligible  ...  Acknowledgements The authors wish to thank A.M. Mäkelä, J. Nikki, and T. Palomäki for their help during the experiment.  ...

Recognition of Rapid Speech by Blind and Sighted Older Adults

Sandra Gordon-Salant, Sarah A. Friedman
2011 Journal of Speech, Language and Hearing Research  
Rather, frequent listening to speech at rapid rates, which was highly correlated with performance of the older blind adults, may be a useful technique to minimize age-related slowing in speech understanding  ...  Purpose-The goal of this study was to determine if older blind participants recognize timecompressed speech better than older sighted participants.  ...  Acknowledgments This research was supported by a MERIT award from the National Institute on Aging, NIH.  ...

Perception of Speech Modulation Cues by 6-Month-Old Infants

Laurianne Cabrera, Josiane Bertoncini, Christian Lorenzi
2013 Journal of Speech, Language and Hearing Research  
Method: Several vocoded speech conditions were designed to: (i) degrade FM cues in 4 or 32 bands, or (ii) degrade AM in 32 bands.  ...  Infants were familiarized to the vocoded stimuli for a period of either 1 or 2 min. Vocoded speech discrimination was assessed using the head-turn preference procedure.  ...  Lorenzi was supported by a grant (HEARFIN Project) from ANR. The authors would like to thank warmly the parents for their participation in this study.  ...

Cochlear neuropathy and the coding of supra-threshold sound

Hari M. Bharadwaj, Sarah Verhulst, Luke Shaheen, M. Charles Liberman, Barbara G. Shinn-Cunningham
2014 Frontiers in Systems Neuroscience  
Animal studies show that noise exposure and aging can cause a loss of a large percentage of auditory nerve fibers (ANFs) without any significant change in measured audiograms.  ...  In humans with normal hearing thresholds (NHTs), paradigms that require listeners to make use of the detailed spectro-temporal structure of supra-threshold sound, such as selective attention and discrimination  ...  deficits involving language such as differences in speech intelligibility.  ...

The role of contrasting temporal amplitude patterns in the perception of speech

Eric W. Healy, Richard M. Warren
2003 Journal of the Acoustical Society of America  
Despite a lack of traditional speech features, novel sentences restricted to a narrow spectral slit can retain nearly perfect intelligibility ͓R. M. Warren et al., Percept.  ...  However, when a 1 3 -octave speech band was partitioned to create a contrasting pair of independently amplitude-modulated 1 6 -octave patterns, some intelligibility was restored ͑experiment 2͒.  ...  ANSI-S3.5, 1997, ''American national standard methods for the calculation of the speech intelligibility index'' ͑American National Standards Institute, New York͒.

Tone Language Speakers and Musicians Share Enhanced Perceptual and Cognitive Abilities for Musical Pitch: Evidence for Bidirectionality between the Domains of Language and Music

Gavin M. Bidelman, Stefanie Hutka, Sylvain Moreno, Joel Snyder
2013 PLoS ONE  
well as complex music perception.  ...  Here, using a crosssectional design, we compared the performance of musicians to that of tone-language (Cantonese) speakers on tasks of auditory pitch acuity, music perception, and general cognitive ability  ...  The task assesses short-term memory of pitch sequences, and is a musical counterpart to the classic digit span test commonly employed to assess verbal working memory (e.g., [62] ).  ...

2013 Cerebral Cortex  
Under noisy listening conditions, visualizing a speaker's articulations substantially improves speech intelligibility.  ...  We consider the observation that the multisensory speech system recovers substantially in adolescence as an indication that it is likely amenable to intervention during earlier childhood, with potentially  ...  Funding Primary support for this work was provided through a grant from the US NIH (MH085322 to J.J.F. and S.M.).  ...

Rinu Annie Roy
2018 Global Journal of Otolaryngology  
Working memory has a crucial role in one's effective communication, especially for the speech and language comprehension.  ...  The purpose of this study is to compare the auditory working memory capacity (AWMC) in normal hearing adults and adults with mild to moderate hearing loss using digit span tasks from WAIS-IV.  ...  It is observed as a reduction in the speech recognition ability of the under stimulated ear.  ...

Processing Complex Sounds Passing through the Rostral Brainstem: The New Early Filter Model

John E. Marsh, Tom A. Campbell
2016 Frontiers in Neuroscience  
Those corticofugal connections constrain the processing of complex sounds such as speech at the level of the brainstem.  ...  Turning to the effects of a visually presented sensory or memory load on auditory processes, there is a load-dependent reduction of that processing, as manifest in the auditory brainstem responses (ABR  ...  Increasing sensory load by degrading to-be-remembered serial recall visual digit items (A) with Gaussian noise (B) reduces the deviant effect (C), whereby an occasional change-in-voice of to-be-ignored  ...

Acoustics of ancient Greek and Roman theaters in use today

Anders Christian Gade, Konstantinos Angelakis
2006 Journal of the Acoustical Society of America  
It was found that the quality of the processed sound tended to degrade as the head yaw rotation increased.  ...  In contrast to previous findings of an interlanguage speech intelligibility benefit ͑ISIB͒ for sentences, non-native listeners found native speech more intelligible than non-native speech.  ...  It is shown that in the presence of spatial and temporal waveguide perturbations ͑such as the sound-speed profile in the water column or the sea bottom͒ structure of a TF diagram and its temporal behavior  ...
