Phonetics and Phonology
Phonetics and phonology are related, dependent fields for
studying aspects of language. Phonetics is the study of sound in speech;
phonology is the study (and use) of sound patterns to create meaning. Phonetics
focuses on how speech is physically created and received, including study of
the human vocal and auditory tracts, acoustics, and neurology. Phonology relies
on phonetic information for its practice, but focuses on how patterns in both
speech and non-verbal communication create meaning, and how such patterns are
interpreted. Phonology includes comparative linguistic studies of how cognates,
sounds, and meaning are transmitted among and between human communities and
languages.
The Vocal Organs
Speech is produced by the vocal organs. Every language has a
definite set of speech sounds, and every sound can be described with reference
to the vocal organ that is used to produce it. In this way sounds occurring in
different languages can be compared, and foreign language learners can be
helped to overcome pronunciation problems that arise from differences between
languages. Knowledge of how the vocal organs function to produce the various
sounds of a language will make near-native sound production possible.
Speech is produced by air from the lungs being processed or
modified by all speech organs above the lungs: the glottis, pharynx, nose,
tongue, and lips. The individual sound is identified by the closure or
narrowing of these organs. If we see the tongue as the active articulator, the
place which does not move can be called the passive articulator. Labels refer
to the place where the closure or narrowing occurs, which means that the name
normally refers to the passive articulator.
The speech sounds often have their names from the Latin name
of the vocal organ:
Nasal sounds: through nose (velum down)
Oral sounds: through
mouth (velum up)
Stops: full oral closure
Fricatives: partial oral closure (friction)
Approximants: narrowing (no friction)
Labial: from labium, lip(s) active
Dental: from dentes, teeth active
Alveolar: Alveoles, teeth ridge active
Palatal: Palate, hard palate active
Velar: Velum, soft palate active
Glottal: Glottis, vocal cords active

Voiced and voiceless
- Glottis:
The airstreams from the lungs moves up through the trachea, or windpipe,
and through the opening between the vocal cards.
- Supra
glottal cavities: The parts of the vocal tract above the glottis
- Voiceless:
If the vocal cords are apart, the airstreams is not obstructed at the
glottis and it passes freely into the supra glottal cavities (p, t, k, s).
- Voiced:
If the vocal cords are together, the airstreams forces its way through and
causes them to vibrate (b, d, g, z).
Nasal and Oral
- Nasal:
Air escapes not only through the mouth (when you open your lips) but also
through the nose (m, n, ŋ)
- Oral:
When nasal passage is blocked in this way, the air can escape only through
the mouth.
Places of Articulation
- Bilabial:
at lips (p, b, m, w)
- Labiodental:
between the lower lip and upper teeth (f, v)
- Interdental:
between the tongue and the alveolar ridge (t, d, s, z, n, l)
- Pabial:
between tongue and the palate (š, ž, č, ĵ, ğ).
- Velar:
between tongue and velum (k, g, ŋ).
- Glottal:
at glottis (the space between the vocal cords) (n).
Manner of Articulation
- Stops
Two articulators (lips, tongue, teeth) are brought together
such that the flow off air through the vocal tract is completely blocked (p, b,
c, d, g, k).
- Fricatives
Two articulators are brought near each other such that the
flow of air is impeded but not completely blocked (f, v, ө, o, s, z, š, ž, h).
- Affricatives
Articulations corresponding to affricatives are those that
begin like stars and end like fricatives (č, ĵ).
- Nasal
Air flow through the mouth is completely blocked but the
velum is lowered, forcing the air through the nose (m, n, ŋ)
- Liquids
A cover term for all L-like and R-like articulations (l, r).
- Glides
The vocal tract is constricted, but not enough to block or
impede the air flow (w, y).
Syllabic Sounds
- Vowel
are produced with no oral obstruction whatsoever.
- Consonant: Oral and nasal stops, fricatives, affricatives, liquids, and
glides all have some degree of obstruction.
you can also lear how to spech a symbol in BBC Radio, You can visit the radio and learn and listen how to speech , you can learn in here.
Thank you for readig my Blog , sorry for my mistake about spelling or anything :))
