Articulatory Phonetics
investigates the functioning of one’s speech 
apparatus and mechanism. It is based on profound knowledge of physiology and 
the structure of one’s speech apparatus. While investigating the articulatory aspect 
of speech sounds both subjective and objective methods are employed: the method 
of direct observation (concerning the lips & the tongue movements) – subjective 
method and X-ray photography and X-ray cinematography (objective methods).
Acoustic Phonetics
studies the 
acoustic properties of sounds (quantity, 
timber/voice quality, intensity, the pitch 
of the voice and temporal factor) in 
terms of the frequency of vibration and 
the amplitude of vibration in relation to 
time. The analysis begins with a 
microphone, which converts the air 
movement into corresponding electrical 
activity. While investigating the acoustic 
aspect 
of 
speech 
sounds 
special 
Key points for discussion: 

Theoretical foundations of phonetic and phonological typologies 

Differences between phonetics and phonology

Comparison of vowel and consonant phonemes 

Stress, intonation, assimilation, dissimilation, reduction, accent, 
rhythm and pause.

laboratory equipment is employed: spectrograph, intonograph, sound analyzing & 
sound synthesizing machines.
Auditory Phonetics 
is aimed at investigating the hearing process which is 
the brain activity. Auditory Phonetics and Acoustic Phonetics are very closely 
connected.
Functional Phonetics
presupposes investigating the discriminatory 
(distinctive) function of speech sounds.
Phonetics can be divided into several types like:
