A speaker adaptive system is developed to adapt its operation to the characteristics of new speakers. The size of vocabulary of a speech recognition system affects the complexity, processing requirements and the accuracy of the system. This is the simplest form of recognition to perform because the end points are easier to find and the pronunciation of a word tends not affect others. Thus, because the occurrences of words are more consistent they are easier to recognise. A continuous speech system operates on speech in which words are connected together, i.e. not separated by pauses.
Continuous speech is more difficult to handle because of a variety of effects.
First, it is difficult to find the start and end points of words. The production of each phoneme is affected by the production of surrounding phonemes, and similarly the the start and end of words are affected by the preceding and following words. Back to Section 6 of the comp.speech FAQ Home Page .
