Document Summary
Sentences: a group of words that express a complete thought. Acoustics: the study of the physical properties of sound: sound spectrogram: shows the amount of energy present in a sound when frequency is plotted against time. Formants: peaks of energy at particular frequencies: formant structure is an important characteristic of speech sounds, all vowels and some consonants have formants. We can describe speech at two levels: phonetics: describes the acoustic detail of speech sounds and how they are articulated, phonology: describes the sound categories each language uses to divide up the space of possible sounds. Aspirated: a sound that is produced with an audible breath. Unaspirated: a sound that is produced without an audible breath. Phoneme: is a basic unit of sound in a particular language. Allophone: phonetic variants of phonemes i. e. , one aspirated, one unaspirated. Auditory or perceptual: emphasizes how sounds are perceived. Acoustic: emphasizes the sound waveform and physical properties.
