Document Summary

When people are talking there are no obvious breaks unless people are pausing when they talk it is also vary fast. You need air coming from your lungs to hit the vocal cords it gathers behind the vocal cords, and when the air pressure is high enough, the vocal cords part releasing air, causing vibration. The frequency can be modulated-you can make different sounds. Sound leaves through your mouth and your nose. When air gets to the vocal tract, it runs into the articulators (teeth, tongue, lips) We need to understand that we have to divide sounds into two types: vowels and consonants. When you describe vowel sounds, they are described in two dimensions. This is the part and position of the tongue being used: they are continuous. Voiced- vibration of the vocal cords (bat) Unvoiced- no vibration (pat: 2. manner of articulation. Stop consonants: stopping air and then letting it out.
