TL;DR: The mean scores of the spastic subjects were superior to the athetoids on all speech measures, significantly so for single-word intelligibility and DDK rate even when group inequalities for physical disability and I.Q. were adjusted.

TL;DR: The articulation errors of 32 spastic and 18 athetoid males, aged 17-55 years, were analyzed using a confusion matrix paradigm and it was found that within- manner errors exceeded between-manner errors by a substantial amount.
Abstract: The articulation errors of 32 spastic and 18 athetoid males, aged 17-55 years, were analyzed using a confusion matrix paradigm. The subjects had a diagnosis of congenital cerebral palsy, and adequate intelligence, hearing, and ability to perform the speech task. Phonetic transcriptions were made of single-word utterances which contained 49 selected phonemes: 22 word-initial consonants, 18 word-final consonants and nine vowels. Errors of substitution, omission and distortion were categorized on confusion matrices such that patterns could be observed. It was found that within-manner errors (place or voicing errors or both) exceeded between-manner errors by a substantial amount, more so on final consonants. The predominant within-manner errors occurred on fricative phonemes for both initial and final positions. Affricate within-manner errors, all of devoicing, were also frequent in final position. The predominant between-manner initial position errors involved liquid-to-glide and affricate-to-stop changes, and for final position, affricate-to-fricative. Phoneme omission occurred three times more frequently on final than on initial consonants. The error data of individual subjects were found to correspond with the identified overall group patterns. Those with markedly reduced speech intelligibility demonstrated the same patterns of error as the overall group. The implications for treatment are discussed.

TL;DR: In this case study, a 59-year-old male with progressive supranuclear palsy and hypokinetic dysarthria wore a small, solid state, battery operated, delayed auditory feedback device to reduce speech rate and to aid speech intelligibility.

TL;DR: The study attempted to determine what groupings of speech dimensions describe the ataxic speech and if the subjects could be grouped by their speech symptoms, and showed that more than one pattern of dysarthria could occur in one family.

TL;DR: Postoperative treatment local injection of adriamycine, irradiation and immunotherapy with picibanil were performed, and then left hemiparesis was markedly improved without sign of recurrence, and the speech function of thalamus and crossed aphasia with dextrales were discussed.
Abstract: We present a rare case of thalamic germinoma with crossed aphasia in a dextral. A patient, 17-year-old righat-handed male, was admitted to Nippon Medical School Hospital with chief complaints of headache, abnormality of visual field and speech disturbance. There were pigmentations on the back of hand, foot and the perineum. Neurological examination revealed left homonymous hemianopsia, right slight degree of ptosis, left facial palsy, a mild paresis of the left upper extremity and motor aphasia. Right carotid angiography showed marked unrolling and midline shift of right anterior cerebral artery. CT scan revealed ring-like high density area in the right thalamic region, which was enhanced after constant infusion. Brain scintigraphy also showed an abnormal accumulation at the same site. The hen-egg sized tumor of 40 g. weight was almost totally removed by the right fronto-parietal craniotomy. The tumor was characterized histologically by the so-called two cell pattern with teratomatous components. As postoperative treatment local injection of adriamycine, irradiation and immunotherapy with picibanil were performed, and then left hemiparesis was markedly improved without sign of recurrence. Language evaluation was performed after operation. There were dysarthria, remarkable word amnesia, paraphasia and perseveration. Repetition was also impaired. His speech function was concluded to be a mixed type aphasia mainly composed of Broca's aphasia. The speech function of thalamus and crossed aphasia with dextrales were discussed.

TL;DR: A clear understanding of the relationship among basic neuroanatomy, neurophysiology, neuropathology, and functional clinical assessment will provide the clinician with valuable diagnostic information that should lead to early referral to the speech pathologist for appropriate management.
Abstract: Disorders of motor speech may result from impairments in basic motor control systems similar to those causing motor disturbances of the trunk and extremities. Dysarthria and dyspraxia are two distinct disorders of motor speech which differ in both pathologic localization and clinical presentation. These motor speech disorders must be clearly differentiated from other linguistic disorders which result from brain damage. A clear understanding of the relationship among basic neuroanatomy, neurophysiology, neuropathology, and functional clinical assessment will provide the clinician with valuable diagnostic information. This should lead to early referral to the speech pathologist for appropriate management.

TL;DR: This work has interfaced a microcomputer with a voice synthesizer to produce a personal, (weakly) intelligent, and quick verbal response speech prosthesis useful for people who are unable to speak.
Abstract: We have interfaced a microcomputer with a voice synthesizer to produce a personal, (weakly) intelligent, and quick verbal response speech prosthesis useful for people who are unable to speak (Colby, Christinaz, and Graham, 1978) The intelligent speech prosthesis (ISP) is designed to aid those physically handicapped who are unable to speak due to a great variety of medical, neurological or surgical reasons In its current state the ISP/1 can be used by users having communication disorders such as aphonia (loss of voice), dysphonia (an impairment of voice), or dysarthria (impairment in articulation) unaccompanied by damage to the semantic syntactic mechanisms of the language system However, there exists a group of potential users who have some degree of damage in the semantic syntactic mechanisms of the language system It is for a subgroup of this population, those people having word finding difficulties, that the development of an ISP/2 with a lexical memory and associative network is necessary
