Phonics
What is phonetics?
Phonetics is all about studying the sounds we make when we talk.

The three branches of Phonetics
Acoustic Phonetics
This is the study of the sound waves made by the human vocal organs for communication and how the sounds are transmitted. The sound travels through from the speaker's mouth through the air to the hearer's ear, through the form of vibrations in the air. Phoneticians can use equipment like Oscillographs and Spectographs in order to analyse things like the frequency and duration of the sound waves produced. Acoustic phonetics also looks at how articulatory and auditory phonetics link to the acoustic properties.
Auditory Phonetics
This is how we perceive and hear sounds and how the ear, brain and auditory nerve perceives the sounds. This branch deals with the physiological processes involved in the reception of speech.
Articulatory Phonetics
Articulatory phonetics is interested in the movement of various parts of the vocal tract during speech.The vocal tract is the passages above the larynx where air passes in the production of speech. In simpler terms which bit of the mouth moves when we make a sound.
VPM labels is a term that is used in phonetics, it means Voice Place Manner labels. These labels are given to sounds, in order to describe where the sound is produced, how and whether it is voiced or unvoiced (voiceless).
Check out this diagram to help you see where exactly the articulators are.
Voiced and Voiceless sounds
Voiced sounds are sounds vibrate the vocal chords, you can feel this in the throat. Whereas voiceless sounds don't vibrate the vocal chords. Why not give it a go! Place two fingers on the front of your throat and make the /z/ sound as in buzz, do you feel your vocal chords vibrating? Now try doing the same thing but making the /s/ sounds as in grass, what do you feel now? The /s/ sound is a voiceless sound and the /z/ sound is voiced.
Place of Articulation
Speech sounds are classified in terms of which articulators are used, in other words, which bit of the mouth is used in making the sound. Here are some basic classifications to get you started.
Manner of Articulation
Manner of articulation is how the tongue, lips and jaw along with other speech organs are involved when making a sound.
The manners:
Plosive (stop)
Sounds that are made with complete a complete stop of air flow in the vocal tract. Sounds like /p/, /b/, /t/ and /k/.
Nasal
Sounds that are made where air escapes through the nasal cavity. Sounds like /n/ and /m/.
Fricative
A sound produced by a near complete stoppage of air. Sounds like /s/, /z/ or /f/.
Approximant
Sound made where one articulator comes close to another without causing audible friction. Sounds like /w/ or /r/.
Lateral Approximant: Where air escapes through the sides of the tongue, however the tongue blocks the air from going through the middle of the mouth. Sounds like /l/.
Affricate
A sound made that starts like a plosive and then releases into a fricative. Sounds like /dʒ/ and /tʃ/.
Now we know if a sound is voiced or voiceless, the place of articulation and manner of articulation we can start to make VPM labels (Voice Place Manner labels).
For each sound we need to decide, if its voiced or voiceless and where and how the sound is made. Here are a few examples:
/s/- Voiceless Alveolar Fricative
/b/- Voiced Bilabial Plosive
/m/- Voiced Bilabial Nasal
/θ/- Voiceless Dental Fricative
