Document Summary
Language relies on well defined patterns: patterns in how individual words are used, patterns in how words are put together into phrases. Speech is produced by airflow from the lungs that passes through the larynx and from there, through the oral and nasal cavities. Different vowels are created by movements of the lips and tongue that change the size and shape of the oral cavity. Consonants are produced by movements that temporarily obstruct airflow through the vocal tract. There exist voiced vs. unvoiced sounds: voiced include: v,z,n, unvoiced: s,t,,k. Speech segmentation: the first step toward phoneme identification, sliving the stream of speech into appropriate segments. Ambiguity in segmentation: often when we speak, there is no gap between the sounds carrying different words. The perception that there exist brief causes between words in speech we hear is an illusion: we hear pauses that aren"t actually there.
