“…This may be due to the associated dysarthria, which can affect all speech components. This is supported by a study conducted by Odell et al [25], which stated that AOS showed no effect on voice and resonance. Patients with isolated AOS are needed to further study the effect of AOS on various speech components.…”

Background Apraxia of speech can be defined as an articulation disorder that results from impairment of the capacity to order the positioning of speech musculature and the sequencing of muscle movements for volitional production of phonemes and sequences of phonemes. Objective The aim of this study was to adapt the Apraxia Battery for Adults II (ABA II) test to suit the Egyptian culture in order to apply this test for assessing Egyptian apraxic patients for proper management of this ailment. Subjects and methods This study was conducted on two groups: the first group consisted of 56 adult patients with expressive aphasia and/or dysarthria, who were evaluated with ABA II to detect any apraxic elements. The second group consisted of 100 healthy adults who served as the control group and were evaluated by ABA II to yield cutoff scores. Test reliability was assessed by internal consistency reliability using reliability coefficient α (Cronbach’s α). Test validity was measured on the basis of content validity, concurrent validity, and group differentiation. Results Reliability of the ABA II test was proved to be high, on the basis of the high values of coefficient α obtained for all test items (0.746–0.937), denoting an intercorrelation between test items. Validity of the ABA II was proven by three methods: content validity, concurrent validity (correlation matrix between different items of the test was determined and there was a strong correlation between the test items), and group differentiation (comparison of the test results between apraxic patients, nonapraxic patients, and controls was done and statistically significant differences were found between the scores of all test items among these groups.) The test was proven to be sensitive and specific. Conclusion The results were highly significant and were capable of discriminating between normal subjects and apraxic patients.

“…An fMRI study that compared speech perception and production to the perception and production of humming noises, reported in both conditions that the overlapping activation area for perception and production (i.e., the area responsible for sensory-motor conversion) was located in area Spt of the ADS ( Hickok et al , 2003). Supporting evidence for the role of the ADS in the production of prosody are also studies reporting that patients diagnosed with apraxia of speech are additionally diagnosed with expressive dysprosody ( Odell et al , 1991; Odell & Shriberg, 2001; Shriberg et al , 2006 - FOXP2 affected individuals). Finally, the evolutionary account proposed here from vocal exchange of calls to a prosodic-based language is similar to the recent development of whistling languages, since these languages were documented to evolve from exchanging simple calls used to report speakers’ locations into a complex semantic system based on intonations ( Meyer, 2008).…”

From where to what: a neuroanatomically based evolutionary model of the emergence of speech in humans

In the brain of primates, the auditory cortex connects with the frontal lobe via the temporal pole (auditory ventral stream; AVS) and via the inferior parietal lobe (auditory dorsal stream; ADS). The AVS is responsible for sound recognition, and the ADS for sound-localization, voice detection and integration of calls with faces. I propose that the primary role of the ADS in non-human primates is the detection and response to contact calls. These calls are exchanged between tribe members (e.g., mother-offspring) and are used for monitoring location. Detection of contact calls occurs by the ADS identifying a voice, localizing it, and verifying that the corresponding face is out of sight. Once a contact call is detected, the primate produces a contact call in return via descending connections from the frontal lobe to a network of limbic and brainstem regions.Because the ADS of present day humans also performs speech production, I further propose an evolutionary course for the transition from contact call exchange to an early form of speech. In accordance with this model, structural changes to the ADS endowed early members of the genus Homo with partial vocal control. This development was beneficial as it enabled offspring to modify their contact calls with intonations for signaling high or low levels of distress to their mother. Eventually, individuals were capable of participating in yes-no question-answer conversations. In these conversations the offspring emitted a low-level distress call for inquiring about the safety of objects (e.g., food), and his/her mother responded with a high- or low-level distress call to signal approval or disapproval of the interaction. Gradually, the ADS and its connections with brainstem motor regions became more robust and vocal control became more volitional. Speech emerged once vocal control was sufficient for inventing novel calls.
