言语感知受到听觉处理的限制。虽然刚出生的婴儿有一个不成熟的听觉系统和有限的语言经验，他们表现出显着的言语感知技能。为了评估新生儿处理语音复杂声学线索的能力，我们结合了近红外光谱（NIRS）和脑电图（EEG）来测量大脑对辅音不同音节的反应。音节在三种条件下呈现：（i）语音的原始时间调制[幅度调制（AM）和频率调制（FM）]，（ii）快速和慢速AM，但不是FM，或（iii）只有最慢的AM（
Speech perception is constrained by auditory processing. Although at birth infants have an immature auditory system and limited language experience, they show remarkable speech perception skills. To assess neonates' ability to process the complex acoustic cues of speech, we combined near-infrared spectroscopy (NIRS) and electroencephalography (EEG) to measure brain responses to syllables differing in consonants. The syllables were presented in three conditions preserving (i) original temporal modulations of speech [both amplitude modulation (AM) and frequency modulation (FM)], (ii) both fast and slow AM, but not FM, or (iii) only the slowest AM (
