“…Research involving online voice perturbation and FF shifting has shown that people tend to compensate for a change of FF in the realtime auditory feedback during vocal production, either by shifting their FF in the direction of the feedback signal (19,20) or in the opposite direction (20,38,39). The participants in our experiment in the sync condition tended to follow the stimulus rather than compensate for it in the opposite direction.…”

When we carry out an act, we typically attribute the action to ourselves, the sense of agency. Explanations for agency include conscious prior intention to act, followed by observation of the sensory consequences; brain activity that involves the feed-forward prediction of the consequences combined with rapid inverse motor prediction to fine-tune the action in real time; priming where there is, e.g., a prior command to perform the act; a cause (the intention to act) preceding the effect (the results of the action); and commonsense rules of attribution of physical causality satisfied. We describe an experiment where participants falsely attributed an act to themselves under conditions that apparently cannot be explained by these theories. A life-sized virtual body (VB) seen from the firstperson perspective in 3D stereo, as if substituting the real body, was used to induce the illusion of ownership over the VB. Half of the 44 experimental participants experienced VB movements that were synchronous with their own movements (sync), and the other half asynchronous (async). The VB, seen in a mirror, spoke with corresponding lip movements, and for half of the participants this was accompanied by synchronous vibrotactile stimulation on the thyroid cartilage (Von) but this was not so for the other half. Participants experiencing sync misattributed the speaking to themselves and also shifted the fundamental frequency of their later utterances toward the stimulus voice. Von also contributed to these results. We show that these findings can be explained by current theories of agency, provided that the critical role of ownership over the VB is taken into account.agency | body-ownership illusion | rubber-hand illusion | illusory speaking | vibrotactile stimulation T here is growing evidence that the brain does not treat our body as relatively fixed, changing only slowly through time, but that its body representation demonstrates high plasticity. Although this is counter to common sense, a number of findings have shown that simple experimental manipulations can generate the illusion that an external object is part of our body (1, 2), that a plastic manikin (3, 4), and even a body displayed in immersive virtual reality (IVR), is our body (5-7). Furthermore, evidence suggests that such illusions have physiological and psychological consequences. For example, the rubber-hand illusion (RHI), where participants feel a somatic sense of ownership over a rubber hand through synchronous multisensory stimulation on the rubber and corresponding hidden real hand (1), has been shown to lead to a cooling of the real hand (8) as well as an increase in its histamine reactivity (9). The RHI over a black rubber hand can lead to a reduction of implicit racial bias in light-skinned people (10). When light-skinned people have a dark-skinned VB that apparently substitutes their own body, in IVR-as seen directly and in a virtual mirror, and that moves like themselves-they have the illusion that the body is theirs, which also results in a reduction o...

“…The authors proposed that intonation patterns "appeared to be programmed into the speech production system at a "high level" independent of peripheral monitoring" (Mallard et al, 1978). The pitch shift studies by Larson and coworkers (Burnett et al, 1998;Larson et al, 2000) suggest than even when intonation patterns are pre-programmed, a perturbation in auditory feedback can have an immediate effect on pitch control presumably via changes in laryngeal muscle activity. It remains to be seen to what degree perturbations affecting mucosal sensation can alter laryngeal control in humans.…”

Laryngeal muscle control may vary for different functions such as: voice for speech communication, emotional expression during laughter and cry, breathing, swallowing, and cough. This review discusses the control of the human laryngeal muscles for some of these different functions. Sensorimotor aspects of laryngeal control have been studied by eliciting various laryngeal reflexes. The role of audition in learning and monitoring ongoing voice production for speech is well known; while the role of somatosensory feedback is less well understood. Reflexive control systems involving central pattern generators may contribute to swallowing, breathing and cough with greater cortical control during volitional tasks such as voice production for speech. Volitional control is much less well understood for each of these functions and likely involves the integration of cortical and subcortical circuits. The new frontier is the study of the central control of the laryngeal musculature for voice, swallowing and breathing and how volitional and reflexive control systems may interact in humans.

“…For humans, at least, there is additional evidence that there are real-time contributions of auditory feedback to the control of ongoing vocal production. This has been demonstrated by various perturbations of auditory feedback that elicit disruptions of ongoing speech (Lee, 1950;Elman, 1981;Howell and Archer, 1984;Houde and Jordan, 1998;Larson et al, 2000). For example, exposure to delayed auditory feedback results in speech abnormalities including missequencing of syllables and slowing of speech (Lee, 1950;Howell and Archer, 1984).…”

Songbirds and humans both rely critically on hearing for learning and maintaining accurate vocalizations. Evidence strongly indicates that auditory feedback contributes in real time to human speech, but similar contributions of feedback to birdsong remain unclear. Here, we assessed real-time influences of auditory feedback on Bengalese finch song using a computerized system to detect targeted syllables as they were being sung and to disrupt feedback transiently at short and precisely controlled latencies. Altered feedback elicited changes within tens of milliseconds to both syllable sequencing and timing in ongoing song. These vocal disruptions were larger when feedback was altered at segments of song with variable sequence transitions than at stereotyped sequences. As in humans, these effects depended on the feedback delay relative to ongoing song, with the most disruptive delays approximating the average syllable duration. These results extend the parallels between speech and birdsong with respect to a moment-by-moment reliance on auditory feedback. Moreover, they demonstrate that song premotor circuitry is sensitive to auditory feedback during singing and suggest that feedback may contribute in real time to the control and calibration of song.
