Summary
This study analyzed Cantonese vowels and diphthongs in children aged 10-27 months. Vowel development is influenced by both linguistic frequency and articulatory complexity, with language input becoming dominant by 24 months.
Area of Science:
- Phonetics and phonology
- Child language acquisition
- Speech development
Background:
- Cantonese-speaking children's speech development is understudied.
- Understanding vowel and diphthong acquisition is crucial for identifying developmental patterns.
Purpose of the Study:
- To analyze the accuracy of Cantonese vowel and diphthong production in young children.
- To model the developmental trajectory of vowels and diphthongs based on feature complexity.
- To identify linguistic and articulatory factors influencing this development.
Main Methods:
- Collected spontaneous speech samples from 40 Cantonese-speaking children (10-27 months).
- Transcribed and analyzed over 7,000 vowels and diphthongs.
- Developed a feature complexity model to predict developmental routes.
Main Results:
- Identified two key factors influencing development: linguistic frequency and articulatory feature complexity.
- Observed an early reliance on feature complexity (15-18 months).
- Found that ambient language influences supersede feature complexity by 24 months.
Conclusions:
- Vowel and diphthong development in Cantonese is shaped by both intrinsic articulatory properties and extrinsic linguistic input.
- The relative importance of these factors shifts during early language acquisition.

01:13The Cochlea
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
01:03Modes of Standing Waves - I
A close look at earthquakes provides evidence for the conditions appropriate for resonance, standing waves, and constructive and destructive interference. A building may vibrate for several seconds with a driving frequency matching the building's natural frequency of vibration; this produces a resonance that results in one building collapsing while the neighboring buildings do not. Often, buildings of a certain height are devastated, while other taller buildings remain intact. This phenomenon...
01:11The Auditory Ossicles
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

01:01Tongue
The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...

01:24Components of Language
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs. “eh”). Phonemes combine to...
01:22Language Development
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
