Define instrumentation in advanced phonetics and phonology ?

Instrumentation in advanced phonetics and phonology refers to the use of specialized tools and equipment to analyze and study speech sounds. This can include devices such as spectrographs, electroglottographs, and ultrasound machines, which allow researchers to measure and visualize various aspects of speech production and perception. By using instrumentation, researchers can gain a more detailed understanding of the acoustic properties of speech sounds and how they are produced by the vocal tract. This can help to uncover patterns and relationships in phonetic and phonological processes that may not be apparent through auditory analysis alone.
