[Rehilamiento: description]

Area of Science:

• Phonetics and acoustics of speech production.
• Linguistic analysis of Argentine Spanish.
• Auditory perception of fricative sounds.

Context:

• Investigates the acoustic phenomenon known as 'rehilamiento' in Buenos Aires Spanish.
• Analyzes the articulatory and acoustic correlates of voiced fricatives.
• Examines gender-based phonetic variations in speech.

Purpose:

• To describe the acoustic characteristics of 'rehilamiento'.
• To identify the articulatory constrictions responsible for 'rehilamiento'.
• To compare the realization of [z] between male and female speakers.

Summary:

• 'Rehilamiento' is characterized as a stochastic acoustic field superimposed on a periodic field, resulting from constrictions at the vocal cords and pharynx.
• Auditory perception identifies 'rehilamiento' as voiced friction.
• Oscillograms show that men maintain the voiced quality of [z] more than women in Buenos Aires Spanish.

Impact:

• Provides insights into the phonetic realization of 'rehilamiento'.
• Highlights gender-based differences in the production of voiced fricatives.
