Document Summary
The speech segmentation problem: there are no silences between words, there are more silences between clauses. Solutions to this problem in language acquisition: hear certain sounds and attribute to begin words and the ending of words. Another thing you can use is stress, in english our stress patterns is word initial stress or weak-strong stress patters. This is a process based on our native language where we assume certain things about language. In english, if we yell gorp as we see a frog, an infant will assume the word meant frog rather than green, leg, or whatever. Fast mapping can occur through constraints, like elimination. If we say lychee and are provided a bunch of fruits that we know and one that we don"t know, we will assume the new word goes with the object we also don"t know. Lexical contrast: assume that each new word means something unique.
