Observation of limb movements in human subjects resulted in increased motor-evoked potential (MEP) amplitude elicited by magnetic stimulation of motor cortex in the muscles involved in that movement, suggesting that an observation–execution matching (OEM) system exists in humans. We investigated whether the OEM system is activated by speech gestures presented in the visual and auditory modalities. We found that visual observation of speech movement enhanced MEP ampli- tude specifically in…

Observation-execution matching and action inhibition in human primary motor cortex during viewing of speech-related lip movements or listening to speech
Seeing and hearing speech excites the motor system involved in speech production
Modulation of Motor Excitability during Speech Perception: The Role of Broca's Area
TLDR
The results show that during auditory speech perception, there is increased excitability of motor system underlying speech production and that this increase is significantly correlated with activity in the posterior part of the left inferior frontal gyrus (Broca's area), which is proposed to primes the motor system in response to heard speech even when no speech output is required.

Excitability of the motor system: A transcranial magnetic stimulation study on singing and speaking
Using TMS to study the role of the articulatory motor system in speech perception
TLDR
TMS studies have provided support for the view that the motor structures that control the movements of the articulators contribute not only to speech production but also to speech perception.
The Motor Network Reduces Multisensory Illusory Perception
TLDR
Functional magnetic resonance imaging and transcranial magnetic stimulation reveal that activity in these areas of the motor network increased when the audiovisual stimuli were incongruent, and that the increased activity was negatively correlated with perception of the McGurk effect.
Mu wave suppression during the perception of meaningless syllables: EEG evidence of motor recruitment
Effects of seeing and hearing speech on speech production: a response time study
TLDR
These findings support previous research suggesting a close relationship between speech perception and production by demonstrating that viewing speech can ‘prime’ the authors' motor system for subsequent speech production.
Utility of TMS to understand the neurobiology of speech
TLDR
Transcranial magnetic stimulation is an innovative tool to investigate processing of speech perception and imitation and has provided strong evidence that the sensory system is critically involved in mapping sensory input onto motor output and that the motor system plays an important role in speech perception.

TLDR
It is concluded that in humans there is a system matching action observation and execution that resembles the one recently described in the monkey.
Lateralization of phonetic and pitch discrimination in speech processing.
TLDR
Processing changes in pitch produced activation of the right prefrontal cortex, consistent with the importance of right-hemisphere mechanisms in pitch perception.
PET studies of phonetic processing of speech: review, replication, and reanalysis.
TLDR
The findings support a model whereby articulatory processes involving a portion of Broca's area are important when phonetic segments must be extracted and manipulated, whereas left posterior temporal cortex is involved in perceptual analysis of speech.

Action recognition in the premotor cortex.
TLDR
It is proposed that mirror neurons form a system for matching observation and execution of motor actions, similar to that of mirror neurons exists in humans and could be involved in recognition of actions as well as phonetic gestures.
Time course of corticospinal excitability in reaction time and self‐paced movements
TLDR
The results show that motor preparation that begins 1.5 to 2 seconds before self‐paced movement is not associated with increased corticospinal excitability, and supports the hypothesis that ERS may be related to an inactive, idling state of the motor cortex.
A specialization for speech perception.
TLDR
The phonetic module has certain properties in common with modules that are "closed" (for example, sound localization or echo ranging in bats) and, like other members of this class, is so placed in the architecture of the auditory system as to preempt information that is relevant to its special function.
