Three experiments were conducted to ascertain the relative salience of two cues for final consonant voicing in infants and adults. Experiment 1 was designed to investigate infant perception of periodicity of burst, vowel duration, and the two cues combined in a cooperating pattern. Experiment 2 was designed to examine infant perception of these same cues but in a conflicting pattern, that is, with extended duration associated with the voiceless final plosive. Experiment 3 examined perception of the stimuli from Experiments 1 and 2 with adult subjects. Results indicate that in both adults and infants combined cues facilitate discrimination of the phonemic contrast regardless of whether the cues cooperate or conflict. The three experiments taken together do not support a phonetic interpretation of conflicting/cooperating cues for the perception of final stop consonant voicing. Potential psychoacoustic explanations are discussed.
