title: On levels of description in speech research.
abstract: Many researchers are linguistic category names (consonants, vowels, syllables) to refer to observations and measurements made in records of the acoustic speech signal. The present paper serves as a remainder that linguistic categories are abstract and have no physical properties, and that, therefore, their physical correlates in the speech wave are appropriately described in acoustic terms only.
