Auditory vs visual speech timing cues as external rate control to enhance verbal intelligibility in mixed spastic ataxic dysarthric speakers: a pilot study
TLDR
Findings suggested a differential benefit of slowing speech rate to improve intelligibility contingent upon severity of speech deficits.Abstract:
Metronome, singing, and board pacing were used as external rate control techniques for the purpose of comparing the effectiveness of auditory and visual speech timing cues for reducing speech rate and increasing intelligibility in three traumatically brain injured mixed spastic-ataxic dysarthric speakers. A single system design with baseline reversal (ABACAD) was used in this preliminary investigation. Results demonstrated statistically significant (p < 0.05) changes in increased speech intelligibility during all three pacing conditions for the two more involved subjects. Differences between treatment conditions were not statistically significant. However, auditory metronome cuing showed the best results for the two subjects who benefited from rate control. Lower baseline intelligibility was strongly correlated with higher benefit from rate control. Furthermore, the two auditory rhythmic pacing conditions exhibited a close synthronization effect between the frequency rate of the cue and speech rate. Significant correlation coefficients between decreased speech rate and increased intelligibility were only found for the two more involved subjects. These findings suggested a differential benefit of slowing speech rate to improve intelligibility contingent upon severity of speech deficits.read more

Neurobiological foundations of neurologic music therapy: rhythmic entrainment and the motor system.
TL;DR: Temporal rhythmic entrainment has been successfully extended into applications in cognitive rehabilitation and speech and language rehabilitation, and thus become one of the major neurological mechanisms linking music and rhythm to brain rehabilitation.

Making non-fluent aphasics speak: sing along!
TL;DR: The results suggest that singing in synchrony with an auditory model--choral singing--is more effective than choral speech, at least in French, in improving word intelligibility because choral singing may entrain more than one auditory-vocal interface.

The Therapeutic Effects of Singing in Neurological Disorders
TL;DR: Recent evidence on the therapeutic effects of singing is reviewed, and how it can potentially ameliorate some of the speech deficits associated with conditions such as stuttering, Parkinson's disease, acquired brain lesions, and autism are reviewed.

Rhythm in disguise: Why singing may not hold the key to recovery from aphasia
TL;DR: The findings suggest that benefits typically attributed to melodic intoning in the past could actually have their roots in rhythm, and indicate that lyric production in non-fluent aphasics may be strongly mediated by long-term memory and motor automaticity, irrespective of whether lyrics are sung or spoken.

Revisiting the dissociation between singing and speaking in expressive aphasia.
TL;DR: The findings do not support the claim that singing helps word production in non-fluent aphasic patients, but they are consistent with the idea that verbal production, be it sung or spoken, result from the operation of same mechanisms.

The Effect of Rate Control on the Intelligibility and Naturalness of Dysarthric Speech
TL;DR: Sentence intelligibility improved for both groups, with metered pacing conditions associated with the largest improvement in scores, and similar improvements as speaking rates were reduced were not seen for the phoneme intelligibility task; however, one must recognize that sentence and phoneme intelligence tasks are different.

Characteristics of verbal impairment in closed head injured patients
TL;DR: Close head injured patients with a history of coma who manifest motor speech impairment (dysarthria) also manifest linguistic processing deficits, suggesting that linguistic functions are particularly vulnerable in severe head injury.

Ataxic Dysarthria: Treatment Sequences Based on Intelligibility and Prosodic Considerations
TL;DR: Three of the four subjects were taught to use only durational adjustments to signal stress and were able to achieve stress on targeted words consistently and minimize bizarreness which resulted from sweeping changes in fundamental frequency and bursts of loudness.

Management of palilalia with a pacing board.
TL;DR: A pacing device developed as a means of controlling the severely palilalic output of one patient is described, modeled after Luria's suggestion that a treatment program for such patients can be developed successfully by transferring automatic motor acts to a conscious, reactive level.
