Sensitivity and Selectivity of Neurons in Auditory Cortex to the Pitch, Timbre, and Location of Sounds

Jennifer K. Bizley, Kerry M. M. Walker
2010 The Neuroscientist  
In this article, the authors examine evidence that the auditory cortex is necessary for processing the pitch, timbre, and location of sounds, and document how neurons across multiple auditory cortical  ...  We can describe any of these sounds in terms of various independent "features" such as their loudness, pitch, or position in space.  ...  How Does the Auditory Cortex Represent Sound Pitch, Timbre, and Location? Neural Representations of Pitch Neural representations of pitch are likely to arise at the cortical level.  ...

Mapping Pitch Representation in Neural Ensembles with fMRI

T. D. Griffiths, D. A. Hall
2012 Journal of Neuroscience  
Functional magnetic resonance imaging (fMRI) in humans and macaques allows a test of the hypothesis that there is a specialized neural ensemble for pitch within auditory cortex: a pitch center. fMRI measures  ...  The distinction between synaptic activity and spike firing, and species differences encourage caution when comparing BOLD activity in humans and macaques to recordings from single neurons in ferret and  ...  and use of pitch.  ...

Voice Conversion using Convolutional Neural Networks [article]

Shariq Mobin, Joan Bruna
2016 arXiv   pre-print
In this paper we use recent advances in neural networks in order to manipulate the voice of one speaker into another by transforming not only the pitch of the speaker, but the timbre.  ...  Fourier Transforms are capable of capturing the pitch and harmonic structure of the speaker but this alone proves insufficient at identifying speakers uniquely.  ...  Pitch and timbre manipulations using cortical representation of sound.

2006 NeuroImage  
The length of a vocal tract is reflected in the sound it is producing.  ...  Sensory encoding of the acoustic effect of vocal tract length (VTL) depends on a time-stabilized spectral scaling mechanism that is independent of glottal pulse rate (GPR, or voice pitch); we provide evidence  ...  Acknowledgments This work was supported by the VW Stiftung (I/79 783), the Wellcome Trust and the UK MRC (G9900362).  ...

Neural and behavioral investigations into timbre perception

Jean-Pierre Chartrand, Isabelle Peretz, Pascal Belin
2008 Brain Research  
Auditory recognition expertise refers to one's ability to accurately and rapidly identify individual sound sources within a homogeneous class of stimuli.  ...  In the present paper, we briefly review what is known about visual expertise and propose that the same framework can be used in the auditory domain to ask the question of domain specificity for the processing  ...  For instance, the use of sound morphing can enable us to create novel exemplars from combining two natural categories of sounds like voices and musical instruments .  ...
