¡¡¡¡¡¡ Computers have been taught to act and speak, and now the trick is to get them to listen ---- to understand spoken words. So far speech¡¡ 36¡¡ system has been used by workers who need to enter data(Êý¾Ý) into a computer while their hands and eyes are¡¡ 37¡¡ occupied.

¡¡¡¡¡¡ The recognition of a limited vocabulary of single words from a single speaker is pretty much ¡¡38¡¡ problem. Some systems, however, have trouble¡¡ 39¡¡ the noise of crumpling(Èà) paper from the¡¡ 40¡¡ of a human voice.

¡¡¡¡¡¡ Speakers of independent systems that can recognize the same word ¡¡41¡¡ is spoken by many different people can be built by sampling(ÌṩÑùÆ·)how several people say the same words¡¡ 42¡¡ storing several patterns for each word. But the ¡¡43¡¡ for errors are greater and the vocabulary must usually be¡¡ 44¡¡ . Even more difficult is continuous speech. People¡¡ 45¡¡ running words together and even changing some wounds when they speak, so the computer doesn¡¯t know when one word ends and another¡¡ 46¡¡ , making the process much less¡¡ 47¡¡ . It was reported that it took an hour on the largest computer in¡¡ 48¡¡ use to recognize one second of continuous speech.

¡¡¡¡¡¡ Some attempts have been made to¡¡ 49¡¡ continuous speech recognition by¡¡ 50¡¡ the computer some rules of grammar to restrict(ÏÞÖÆ)which word can follow¡¡ 51¡¡ other word. A device(×°ÖÃ)has been developed that has a 5,000-word vocabulary but¡¡ 52¡¡ the speaker to¡¡ 53¡¡ between words.

¡¡¡¡¡¡ These devices, ¡¡54¡¡ at the moment, will represent the first applications(Ó¦ÓÃ)of what is considered a¡¡ 55¡¡ but extremely difficult technology.
