The DIVA model of speech production provides a computationally and neuroanatomically explicit account the network brain regions involved in acquisition production. An overview is provided along with descriptions computations performed different represented model. latest version model, which contains new right-lateralised feedback control map ventral premotor cortex, will be described, experimental results that motivated this component discussed. Application to study treatment communication...
Does the speech motor control system use invariant vocal tract shape targets when producing vowels and semivowels? A 4-part theoretical treatment favoring models whose only are regions in auditory perceptual space over that posit constriction is presented. Auditory target hypothesized to arise during development as an emergent property of neural map formation system. Furthermore, movements planned trajectories space. These then mapped into articulator through a mapping allows equivalent...
Abstract Speakers plan the phonological content of their utterances before release as speech motor acts. Using a finite alphabet learned phonemes and relatively small number syllable structures, speakers are able to rapidly produce arbitrary sequences that fall within rules language. The class computational models sequence planning performance termed competitive queuing have followed K. S. Lashley [The problem serial order in behavior. In L. A. Jeffress (Ed.), Cerebral mechanisms behavior...
Background Brain-machine interfaces (BMIs) involving electrodes implanted into the human cerebral cortex have recently been developed in an attempt to restore function profoundly paralyzed individuals. Current BMIs for restoring communication can provide important capabilities via a typing process, but unfortunately they are only capable of slow rates. In current study we use novel approach speech restoration which decode continuous auditory parameters real-time synthesizer from neuronal...
Abstract This paper describes a self-organizing neural model for eye-hand coordination. Called the DIRECT model, it embodies solution of classical motor equivalence problem. Motor computations allow humans and other animals to flexibly employ an arm with more degrees freedom than space in which moves carry out spatially defined tasks under conditions that may require novel joint configurations. During babbling phase, endogenously generates movement commands activate correlated visual,...
The role of auditory feedback in speech motor control was explored three related experiments. Experiment 1 investigated sensorimotor adaptation: the process by which speakers alter their production to compensate for perturbations feedback. When first formant frequency (F1) shifted heard subjects as they produced vowels consonant-vowel-consonant (CVC) words, subjects' demonstrated compensatory shifts that were maintained when subsequently masked noise-evidence adaptation. 2 discrimination...
The perceptual magnet effect is one of the earliest known language-specific phenomena arising in infant speech development. characterized by a warping space near phonemic category centers. Previous explanations have been formulated within theoretical framework cognitive psychology. model proposed this paper builds on research from both psychology and neuroscience working toward more complete account effect. embodies two principal hypotheses supported considerable experimental literature: (1)...
This study investigated the network of brain regions involved in overt production vowels, monosyllables, and bisyllables to test hypotheses derived from Directions Into Velocities Articulators (DIVA) model speech (Guenther, Ghosh, & Tourville, 2006). The DIVA predicts left lateralized activity inferior frontal cortex when producing a single syllable or phoneme increased cerebellar for consonant-vowel syllables compared with steady-state vowels.Sparse sampling functional magnetic resonance...
Auditory feedback is instrumental in the online control of speech, allowing speakers to compare their self-produced speech signal with a desired auditory target and correct for errors. However, there little account representation “target” “error”: does error depend purely on acoustic distance from target, or enhanced by phoneme category changes? Here, we show an effect vowel boundaries compensatory responses real-time perturbation. While human subjects spoke monosyllabic words,...
Communication with a robot using brain activity from human collaborator could provide direct and fast feedback loop that is easy natural for the human, thereby enabling wide variety of intuitive interaction tasks. This paper explores application EEG-measured error-related potentials (ErrPs) to closed-loop robotic control. ErrP signals are particularly useful robotics tasks because they naturally occurring within in response an unexpected error. We decode operator real time control Rethink...
