Phonetics
The study of the minimal units that make up language.
Articulatory Phonetics
One of the aspects to the study of speech sounds. The study of the production of speech sounds.
Acoustic Phonetics
The second aspect of the study of speech sounds. Also, the study of the transmission and the physical properties of speech sounds.
Auditory Phonetics
The third aspect of the study of speech sounds. Also, the study of the perception of speech sounds.
Consonants
Speech sound produced with a construction somewhere in the vocal tract that impedes airflow.
Vowels
Speech sound produced with at most only a slight narrowing somewhere in the vocal tract, allowing air to flow freely through the oral cavity.
Syllable
A unit of speech—every utterance contains at least one syllable.
Segmental features
The voicing, place, and manner of articulation.
Affricates
Complex sounds, made by briefly stopping the airstream completely and then releasing the articulators slightly so that frication noise is produced.
Length

Segments
The individual units of the speech stream; segments can be further subdivided into consonants and vowels.
Intonation
The pattern of pitch movements across a stretch of speech such as a sentence.
Tone

A stressed syllable is more prominent than an unstressed one.
Compression

Rarefraction
Air molecules are spread farther apart than usual.
Periodic wave
A sound wave, which repeats at regular intervals.
Formats
Peaks in the filter function.
Spectrogram

Aspiration
