We report an investigation of the production of high and low frequency words across four subject groups: 1) young non-brain damaged controls (NBDC1, N=7: mean age 25 years); 2) older non-brain damaged controls (NBDC2, N=6: mean age 53 years); 3) brain damaged controls (BDC, N=3: mean age 64 years), and 4) speakers with apraxia of speech (AOS, N=5: mean age 63 years). The BDC and AOS groups were differentiated by the presence of apraxia. The stimuli used in the study consisted of three repetitions of ten pairs of high-low frequency nouns e.g. bile-mile (high frequency>100 occurrences per million, low frequency <10 occurrences per million). The results from all three repetitions of the acoustic measures (response latency, utterance duration and word duration) of all four groups are presented and discussed with reference to observed patterns of verbo-motor priming, together with implications for phonetic encoding and the motor execution of speech.
