The object model presents a static view of the system and illustrates how different objects collaborate with one another through patterns of interaction. Inheritance, association and aggregation are the three inter-object relationships specified by the object model.

The purpose of Interaction diagrams is to:

1. Model interactions between objects
2. Assist in understanding how a system (a use case) actually works
3. Verify that a use case description can be supported by the existing classes
4. Identify responsibilities/operations and assign them to classes

Tap is up and down movement of the top of the tip of tongue. For example, pronouncing the middle sound in word 'pity' with typical American accent [?]. It is very brief and is produced by a sharp upward throw of the tongue blade. In the production of trill the articulator is set in motion by the current of air [r]. It is a typical sound of Scottish English as in words like 'rye' and 'row'.

Bilabial

This sound is made with two lips (for example, /p/ and /b/). The lips come together for these sounds.

Labiodental

This sound is made when the lower lip is raised to touch the upper front teeth (for example, /f/ and /v/).

Dental

This sound is made with the tongue tip or blade and upper front teeth. For example, say the words thigh, thy and you will find the first sound in each of these words to be dental.

Alveolar

This sound is made with the tongue tip or blade and the alveolar ridge. You may pronounce words such as tie, die, nigh, sigh, zeal, lie using the tip of the tongue or the blade of the tongue for the first sound in each of these words (which are alveolar sounds).

Retroflex

This sound is produced when the tongue tip curls against the back of the alveolar ridge. Many speakers of English do not use retroflex sounds at all but it is a common sound in Pakistani languages such as Urdu, Sindhi, Pashto, Balochi and Punjabi.

Palato-alveolar

This sound is produced with the tongue blade and the back of the alveolar ridge (for example, first sound in each of words like shy, she, show)

Palatal

This sound is produced with front of the tongue and the hard palate (such as the first sound in 'yes'.

Velar

This sound is produced with back of the tongue and the soft palate (such as /k/ and /g/).
