Humans and monkeys were compared in their perception of phoneme boundary shifts along two synthetic stop‐glide /bα‐wα/ continua differing in overall syllable duration (150 vs 320 ms). Humans were first tested with a written identification procedure and showed a boundary shift to longer transition durations with increased syllable duration, as previously reported in the literature. Humans and monkeys were then tested with a low‐uncertainty discrimination procedure but showed little evidence of a sensory‐level discontinuity underlying the identified boundaries: Instead sensitivity tended to follow Weber’s law. Finally, both humans and monkeys were tested with a go/no‐go identification procedure specifically designed for monkeys. Similar stop‐glide boundaries emerged and shifted with increased syllable duration for both species, indicating that monkeys make good models of human stop‐glide sensitivity in identification procedures that involve higher level attentional and memorial processes.
