Speech perception and spoken word recognition: past and present

Area of Science:

• Psycholinguistics
• Auditory Neuroscience
• Developmental Psychology

Background:

• Speech perception research spans over 50 years.
• Significant advancements have been made in understanding infants' and adults' language perception capacities.
• The field has developed sophisticated theories regarding language acquisition, processing, and representation.

Purpose of the Study:

• To provide a selective review of research on speech perception over the past 50 years.
• To examine the historical and theoretical contexts of speech perception research.
• To focus on key areas: speech sound discrimination/categorization, spoken word recognition, and infant language acquisition.

Main Methods:

• Literature review of seminal and recent studies in speech perception.
• Analysis of theoretical frameworks and historical progression in the field.
• Synthesis of findings across different research areas within speech perception.

Main Results:

• Early research established foundational knowledge on speech sound discrimination and categorization.
• Recent work has elucidated the complex processes and representations involved in spoken word recognition.
• Studies demonstrate infants' remarkable innate and developing abilities to perceive their native language.

Conclusions:

• The field of speech perception has made substantial progress in understanding human auditory language capabilities.
• Continued research is vital for refining theories of speech processing, representation, and acquisition.
• Understanding speech perception offers insights into cognitive processes and language development.
