- Abstract
Many researchers rely on analogue voice keys for psycholinguistic research. However, the triggering of traditional simple threshold voice keys (STVKs) is delayed after response onset, and the delay duration may vary depending on initial phoneme type. The delayed trigger voice key (DTVK), a stand-alone electronic device that incorporates an additional minimum signal duration parameter, is described and validated in two experiments. In Experiment 1, recorded responses from a nonword naming task were presented to the DTVK and an STVK. As compared with hand-coded reaction times from visual inspection of the waveform, the DTVK was more accurate than the STVK, overall and across initial phoneme type. Rastle and Davis (2002) showed that an STVK more accurately detected an initial [s] when it was followed by a vowel than when followed by a consonant. Participants' responses front that study were presented to the DTVK in Experiment 2, and accuracy was equivalent for initial [s] in vowel and consonant contexts. Details for the construction of the DTVK are provided.
