Computational Models for Speech Production
Major speech production models from speech science literature and a number of popular statistical “generative” models of speech used in speech technology are surveyed. Strengths and weaknesses of these two styles of speech models are analyzed, pointing to the need to integrate the respective strengths while eliminating the respective weaknesses. As an example, a statistical task-dynamic model o...
متن کاملThe Functional Neuroanatomy of Speech Perception
The processing of heard speech in the brain comprises several stages: After an initial analysis of all sounds, speech and non-speech, in the primary auditory cortex (PAC), speech is identified and processed differently from non-speech sounds to determine its linguistic content. Previous findings show that language-specific processes involve a left-lateralized network of cortical regions in the ...
متن کاملThe new neuroanatomy of speech perception.
Our understanding of speech recognition processes has gradually advanced over the past 50 years, from a state of almost total ignorance to one of well-informed confusion. Technical advances introduced around the middle of the last century enabled detailed description of the spectral patterns and temporal phenomena that characterize vowels and consonants, and extensive perceptual studies were un...
متن کاملTowards a functional neuroanatomy of speech perception.
The functional neuroanatomy of speech perception has been difficult to characterize. Part of the difficulty, we suggest, stems from the fact that the neural systems supporting 'speech perception' vary as a function of the task. Specifically, the set of cognitive and neural systems involved in performing traditional laboratory speech perception tasks, such as syllable discrimination or identific...
متن کاملAge-related changes in the functional neuroanatomy of overt speech production.
Alterations of existing neural networks during healthy aging, resulting in behavioral deficits and changes in brain activity, have been described for cognitive, motor, and sensory functions. To investigate age-related changes in the neural circuitry underlying overt non-lexical speech production, functional MRI was performed in 14 healthy younger (21-32 years) and 14 healthy older individuals (...
