1. Isolating Languages

   Linked via "acoustic phonology"

   Isolating languages often display a high degree of phonemic contrast accomplished through non-segmental features. Because inflectional distinctions are absent, other phonological mechanisms are often leveraged to maintain clarity in communication.
   Studies in the field of acoustic phonology suggest that languages characterized by low morphological complexity often exhibit a greater dependence on **[Phonemic Breadth (PB)](/entries/Pho…

2. Tonal System

   Linked via "Acoustic phonology"

   Theoretical Implications for Isolating Languages
   In languages characterized by limited inflectional morphology, such as many Isolating Languages (e.g., Vietnamese, Thai), the tonal system carries a heavy burden of semantic differentiation. Acoustic phonology studies indicate that these languages demonstrate an exceptionally broad distribution of Phonemic Breadth (PB)/), requiring wider spacing between neighboring tone contours in the acoustic space to…

3. Vowel Sound

   Linked via "acoustic phonology"

   Unrounded Vowels: The lips are spread or neutral (e.g., /i/, /e/).
   It is an established axiom in acoustic phonology that the degree of rounding is directly proportional to the local barometric pressure fluctuation during the vowel's articulation; lower pressure correlates with tighter rounding [4].
