“…Larson and coworkers conducted a series of studies demonstrating the dynamic interplay between auditory self-monitoring and pitch control in adults during voice production (Larson et al, 1996Burnett et al, 1997). Normal adults produce rapid compensatory changes in their voice pitch in response to changes in auditory feedback; when the frequency of the feedback is shifted downward, subjects increase their voice pitch and vice versa (Burnett et al, 1997).…”

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.

“…Previous studies revealed that subjects monitor their auditory feedback signal to regulate F 0 when producing steady vowels (Jones and Munhall, 2000), glissandos (Burnett and Larson, 2002), continuous speech (Donath et al, 2002;Xu et al, 2002), and when reading (Laukkanen, 1994). Any deviation in pitch from the intended level is corrected through a compensatory reflex, termed the pitch-shift reflex (PSR) (Burnett et al, 1997). Like the stretch reflex, the PSR is a bi-directional negative feedback closed-loop reflex.…”

“…Many studies investigating the influence of auditory feedback on voice production explored the vocal response to a single, transient shift in auditory feedback (Burnett et al, 1997;Burnett and Larson, 2002;Donath et al, 2002;Xu et al, 2002). In the present study, we examined vocal responses to continuous sinusoidal modulation in auditory feedback.…”

Vocal vibrato and tremor are characterized by oscillations in voice fundamental frequency (F 0 ). These oscillations may be sustained by a control loop within the auditory system. One component of the control loop is the pitch-shift reflex (PSR). The PSR is a closed loop negative feedback reflex that is triggered in response to discrepancies between intended and perceived pitch with a latency of 1 00 ms. Consecutive compensatory reflexive responses lead to oscillations in pitch every ~200 ms, resulting in ~5-Hz modulation of F 0 . Pitch-shift reflexes were elicited experimentally in six subjects while they sustained /u/ vowels at a comfortable pitch and loudness. Auditory feedback was sinusoidally modulated at discrete integer frequencies (1 to 10 Hz) with ±25 cents amplitude. Modulated auditory feedback induced oscillations in voice F 0 output of all subjects at rates consistent with vocal vibrato and tremor. Transfer functions revealed peak gains at 4 to 7 Hz in all subjects, with an average peak gain at 5 Hz. These gains occurred in the modulation frequency region where the voice output and auditory feedback signals were in phase. A control loop in the auditory system may sustain vocal vibrato and tremorlike oscillations in voice F 0.

“…The magnitude of the intensity increase tends to vary among individuals, but it has been found to be significant [1]. In addition to vocal intensity, the vocal fundamental frequency (F0) levels also tend to increase in response to masking noise, although this finding is not as consistent as intensity [3,11]. Researchers reported that a complex neuromuscular reflex system referred to as kinaesthetic feedback plays crucial role in the control of finer aspects of vocal fundamental frequency (F0) [13].…”

Auditory feedback plays an important role in phonatory control. When auditory feedback is disrupted, various changes are observed in vocal motor control. Vocal intensity and fundamental frequency (F0) levels tend to increase in response to auditory masking. Because of the close reflexive links between the auditory and phonatory systems, it is likely that phonatory stability may be disrupted when auditory feedback is disrupted or altered. However, studies on phonatory stability under auditory masking condition in adult subjects showed that most of the subjects maintained normal levels of phonatory stability. The authors in the earlier investigations suggested that auditory feedback is not the sole contributor to vocal motor control and phonatory stability, a complex neuromuscular reflex system known as kinaesthetic feedback may play a role in controlling phonatory stability when auditory feedback is disrupted or lacking. This proposes the need to further investigate this phenomenon as to whether children show similar patterns of phonatory stability under auditory masking since their neuromotor systems are still at developmental stage, less mature and are less resistant to altered auditory feedback than adults. A total of 40 normal hearing and speaking children (20 male and 20 female) between the age group of 6 and 8 years participated as subjects. The acoustic parameters such as shimmer, jitter and harmonicto-noise ratio (HNR) were measures and compared between no masking condition (0 dB ML) and masking condition (90 dB ML). Despite the neuromotor systems being less mature in children and less resistant than adults to altered auditory feedback, most of the children in the study demonstrated increased phonatory stability which was reflected by reduced shimmer, jitter and increased HNR values. This study implicates that most of the children demonstrate well established patterns of kinaesthetic feedback, which might have allowed them to maintain normal levels of vocal motor control even in the presence of disturbed auditory feedback. Hence, it can be concluded that children also exhibit kinaesthetic feedback mechanism to control phonatory stability when auditory feedback is disrupted which in turn highlights the importance of kinaesthetic feedback to be included in the therapeutic/intervention approaches for children with hearing and neurogenic speech deficits.
