the lips results in a traveling sound wave that the listener perceives as speech. There are then three general categories of the source for speech sounds: periodic, noisy, and impulsive, although combinations of these sources are often present. Examples of speech
All the sounds we make when we speak are the result of muscles contracting. The muscles in the chest that we use for breathing produce the flow of air that is needed for almost all speech sounds; muscles in the larynx produce many different modifications in the flow of air from the chest to the mouth.
the set of features which can describe the sounds of a language while phonology provides the information that has to do with the functional patterning of the sounds in the language.
To represent the basic sound of spoken languages linguists use a set of phonetic symbols called the International Phonetic Alphabet (IPA). The chart below contains all of the IPA symbols used to represent the sounds of the English language. This is the standard set of phonemic symbols for English (RP). Speech can be seen as controlled breathing.
The 44 English sounds can be divided into two major categories – consonants and vowels. A consonant sound is one in which the air flow is cut off, either partially or completely, when the sound is produced. In contrast, a vowel sound is one in which the air flow is unobstructed when the sound is made. The vowel
28.1 Speech Sounds and Phonetic Transcription A letter like ‘p’ or ‘a’ is already a useful model of the sounds of human speech, and indeed we’ll see in Chapter 16 how to map between letters and waveforms.
Phonetics is the study of speech sounds. We are able to segment a continuous stream of speech into distinct parts and recognize the parts in other words. Everyone who knows a language knows how to segment sentences into words and words into sounds.
