Neural processing critical for distinguishing between speech sounds

Neural Processing of Natural Sounds

Auditory-Motor Processing of Speech Sounds

The motor regions that control movements of the articulators activate during listening to speech and contribute to performance in demanding speech recognition and discrimination tasks. Whether the articulatory motor cortex modulates auditory processing of speech sounds is unknown. Here, we aimed to determine whether the articulatory motor cortex affects the auditory mechanisms underlying discri...

Neural networks for speech processing

Neural representation of amplified speech sounds.

OBJECTIVE To determine if (1) evoked potentials elicited by amplified speech sounds (/si/ and /[symbol: see text]/) can be recorded reliably in individuals, (2) amplification alters neural response patterns, and (3) different amplified speech sounds evoke different neural patterns. DESIGN Cortical evoked potentials were recorded in sound field from seven normal-hearing young adults in respons...

Neural processing of amplitude-modulated sounds.

Amplitude modulation (AM) is a temporal feature of most natural acoustic signals. A long psychophysical tradition has shown that AM is important in a variety of perceptual tasks, over a range of time scales. Technical possibilities in stimulus synthesis have reinvigorated this field and brought the modulation dimension back into focus. We address the question whether specialized neural mechanis...
