Arizona Child Acoustic Database Repository.

Area of Science:

• Linguistics
• Speech Science
• Developmental Psychology

Background:

• Childhood speech development involves significant acoustic changes.
• Longitudinal data is crucial for understanding developmental trajectories.
• Existing databases may lack comprehensive longitudinal acoustic data from children.

Purpose of the Study:

• To create a comprehensive longitudinal database of child speech acoustics.
• To capture acoustic variations in vowels and diphthongs during critical growth periods.
• To facilitate research on speech development and acoustic phonetics in children.

Main Methods:

• Collected longitudinal acoustic recordings from 63 children aged 2-7 years.
• Data was gathered at 3-month intervals, including vowels, diphthongs, words, and conversational speech.
• Utilized a protocol designed to capture a wide range of speech sounds and contexts.

Main Results:

• Acoustic recordings are available for download from the University of Arizona Library Repository.
• The database contains detailed speech data from a significant cohort of children.
• The data spans a critical period of speech and language development.

Conclusions:

• Longitudinal recordings offer unique insights into individual child speech development.
• This database supports research into the acoustic characteristics of developing speech.
• The Arizona Child Acoustic Database is a valuable resource for the scientific community.
