Vowels

Vowels:
Sounds in which there is no obstruction to the flow of air as it passes from the larynx to the lips.

Vowels differ from each other (Shape and Position of the Tongue):
  • first, the vertical distance between the upper surface of the tongue and the palate.
  • second, the part of the tongue , between front and back, which is raised highest.
 
 
 
 
Some Examples for the Vowel Sounds:
Cardinal Vowels:
a set of vowels arranges in a close-open, front-back diagram. they are a standard reference system.

Production of speech sounds

Velum (Soft Palate):
Allows air to pass through the nose and through the mouth.
often in speech it is raised so that air cannot escape through the nose.
can be touched by the tongue.

Hard Palate:
"roof of the mouth"

Tongue:
very important articulator, it can be moved into many different places and different shapes.
Parts of the tongue ( tip, blade, front, back, root )

 Lips:
can have different shapes and positions:
  • Rounded: the corners of the lips are brought towards each other and the lips pushed forwards.
  • Spread: the corners of the lips moved away from each other, as for a smile.
  • Neutral: the lips are not noticeably rounded or spread. 
 

Difference between Phonetics and Phonology

Phonetics:
  •  is about the physical aspect of sounds, it studies the production and the perception of sounds.
  • the characteristics of speech sounds (stated with descriptions of speech those sounds, sometimes referred to as "phones") themselves.
  • deals with the production of speech sounds by humans, often without prior knowledge of the language being spoken.
  • describes the articulatory and acoustic properties of phones (speech sounds).
  • relates to the sounds of language .
  • In order to produce sound humans use various body parts including the lips, tongue, teeth, pharynx and lungs. Phonetics is the term for the description and classification of speech sounds, particularly how sounds are produced, transmitted and received.
phoneme:
  • is the smallest unit in the sound system of a language; for example, the t sound in the word top.
  • units of sound that are used in all languages to create words, are the focus of the study of phonetics.
  • Phonetics attempts to understand how each one of these phonemes is physically formed and produced by humans.
  • Phonology is the study of how phonemes are put together and how they create meaning for the speaker of any given language.  
Articulatory phonetics: the study of the production of speech sounds by the articulatory and vocal tract by the speaker.

Acoustic phonetics: the study of the physical transmission of speech sounds from the speaker to the listener.

Auditory phonetics: the study of the reception and perception of speech sounds by the listener.

The International Phonetic Alphabet (IPA) is used as the basis for the phonetic transcription of speech. It is based on the Latin alphabet and is able to transcribe most features of speech such as consonants, vowels, and suprasegmental features.

Phonology:
  •  is about the abstract aspect of sounds and it studies the phonemes (phonemic trancriptions adopt the slash / /).
  • how sounds pattern within a given language (stated in terms of "phonemes").
  • is about patterns of sounds, especially different patterns of sounds in different languages, or within each language, different patterns of sounds in different positions in words etc. 
  • studies how sounds interact as a system in a particular language. 
  • studies how those sounds are put together to create meaning. 
  • the term used for the study of the speech sounds used in a particular language. The distinctive accents that many learners of English have are due to differences between the phonological system of their language and that of English.
