Introduction to Phonetics

Task 1.
Definition of Phonetics:

a. Phonetics is the study of sound in speech.
   (http://www.chegg.com/homework-help/definitions/phonetics-and-phonology-51)

b. Is the branch of linguistics that studies the sounds of one or many language.
    (http://www.wordreference.com/definicion/fon%C3%A9tico)

c. The branch of linguistics that deals with the sounds of speech and their production, combination,            description, and representation by written symbols.
    (http://grammar.about.com/od/pq/g/phoneticsterms.htm)

My own definition:

Phonetics is the branch of linguistics which studies the sounds of human speech, and how they are produced by the voice and representated by writting.


Task 2.
Divisions of Phonetics:

- Articulatory Phonetics: Is the study of sounds of the language and describe what organs involved and which position they are for their production.

- Acoustic Phonetics: Is the study of the oral transmission of speech sounds from the person who speak to the person who listen.

- Auditory Phonetics: Is the study how the ear reacts to sound waves by reception; and how it sounds are interpreted by perception.


Task 3.
The part of phonetics shared in picture and video is Articulatory Phonetics because is the way wich we produce a sound.

[k] as cat:  we use vocal folds and the tongue put in a soft way on the palate.
[p] as put:  we use both lips and the tongue again.
[m] as man:  we use both lips and oral cavity.
[g] as goat: we use the oral cavity
[t] as take: we use the tongue on the alveolar ride.


Acording to the video, the main part involved in the cration of vowel sounds is the nasopharyngeal part.


Task 4.
Acoustic Phonetics.

1. How is a sound produced?

A sound is produced by vibration.

2. How do humans create vibrations in order to produce sounds with their vocal tract?

Vibrations are created by the vocal cords.

3. In which form does sound energy travel?

Sound energy travels in the form of sound waves.

4. What type of wave is sound and what is its characteristic?

Trasverse Waves is like a vibration in spiral, 

and Longitudinal wave is vibration too but in a straight way of the waves.

5. Through which mediums can sound travel?

By solid, liquid or gas way.

6. Where do the waves of sound travel the quickest?

The waves of sound travel quickest by the solid.

Task 5.
Auditory phonetics.

The order of the organs is:  Pina, Ear canal and Eardrum.


Task 6.

About the today´s activity I have learned some interesting information about Phonetics which is the study of the sounds in human speech. Also, I learned that it has three divisions such Articulatory Phonetics, Acoustic Phonetics and Auditory Phonetics.

Those things show us how we produce the sounds in different ways and how those sounds are represented and produced in our vocal tract.
