People often pronounce a word differently when asked to read written material aloud than when speaking spontaneously. These differences may cause problems for those who develop computers that recognize speech. Usually the developers “train” the computers by using samples of written material read by the people who will be using the compute.
The observations above provide most evidence for the conclusion that
(A) It
will be impossible to develop computers that decode spontaneous speech. - WRONG. Like D only. What happens in future is subjective.
(B) When reading written material, people who have different accents
pronounce the same word in the same way as one another. - WRONG. What and how they sound wrt to each other is not an inference that the passage leads to. The scope is diverted.
(C) Computers
may be less reliable in decoding spontaneous speech than in decoding samples that have been read aloud. - CORRECT. POE helps but this can be chosen easily also.
(D) A “trained” computer
never correctly decodes the spontaneous speech of a person whose voice sample was used to train it. = WRONG. A big claim that might not be true.
(E) Computers
are now able to interpret oral speech without error. - WRONG. Not an inference based on the available passage. Needs more assumption to reach such an inference or a possible conclusion.
Answer C.
