The aims of this study were to investigate the adequacy of electronic voice keys for the purpose of measuring naming latency and to test the assumption that voice key error can be controlled by matching conditions on initial phoneme. Three types of naming latency measurements (hand-coding and 2 types of voice keys) were used to investigate effects of onset complexity (e.g., sat vs. spat) on reading aloud (J. R. Frederiksen A. H. Kawamoto & C. T. Kello, 1999). The 3 measurement techniques produced the 3 logically possible results: a significant complexity advantage, a significant complexity disadvantage, and a null effect. Analyses of the performance of each voice key are carried out, and implications for studies of naming latency are discussed.
