Acoustic phonetics deals with the physical aspects of speech sounds associated with the production and perception of speech. Acoustic measurement techniques can be used by speech-language pathologists to assess and treat a variety of speech disorders. In this article, we will review the source-filter theory of speech production, acoustic theory of vowels, and acoustic properties of consonants. We will examine how visual displays of acoustic information in the form of waveforms, amplitude spectra, and spectrograms can be used to analyze aspects of speech that might be difficult to hear and serve to provide biofeedback to clients to improve their speech production.
