3.Speech recognition testing
The accuracy of several SR systems has been shown
in the literature.Some systems have been tested in a
constrained domain (benefiting from a restricted voca-
bulary) and have achieved error rates of less than 20%
[13,27],while other tests of commercial systems have
been anecdotal and tuned by the software vendors to
perform well on the particular test.Further,results
from tests of SR programs can vary,based upon the
complexity of the input[1].
3.1.Tests of multiple systems
Tests have shown that the accuracy for PC-based SR
systems typically ranges from 80 to 99%[2,4].While
some of these tests are not directly comparable,
because of differences in source text,efficiency and
effectiveness measures,and testing periods,they give
an indication of the current state of the technology.
Using standardized protocols and reference test
sets developed by the National Institute of Standards
[26],a mixture of research and commercially available
systems were compared directly,as shown inTable 2.
There was no statistically significant difference in the
results of the first three systems and little difference in
the first seven.However,the last five systems were
clearly less accurate.
3.2.Tests of DragonSystems
DragonSystems is perhaps the US market leader of
PC-based,continuous-speech,general-purpose SR
software.In a test at PC Labs with five subjects using
the software,an accuracy of 89.1% was achieved at 74
wpm as compared to 87.8% at 69 wpm with SR
software from IBM.2In addition,anecdotal tests of
DragonSystems have shown:3
At Raytheon,the average time to process a Material
Requisition Form was reduced from 162 to 44 s
(over 4 h per month) with the aid of voice macros.
An attorney’s staff increased their document pre-
paration productivity by 25%.
An attorney generated text at 120 wpm with 95%
accuracy using the software,and a nurse generated
138 wpm as compared to 40 wpm when typing.
Medical transcripts were produced in one-third of
the time required when typing.
A doctor reduced turnaround time for medical
transcriptions from 2 weeks to 1 day and reduced
his variable transcript service cost from US$ 150
per day to almost zero.
Total medical transcription charges of about US$
100,000 per year at a medical center were reduced
by about 80%.
DragonSystems’NaturallySpeaking Preferred,Ver-
sion 4.01 was selected for our study.Other,perhaps
more accurate,commercial SR systems,such as
LVCR,LIMSI,and CU-HTK,are not readily obtain-
able,and as a market leader,use of the selected system
makes the study more replicable.

托福TPO23的综合写作,
The author offers several explanations for the decline of yellow cedar.However,the speaker rejects all of them by giving several reasons.
First,the speaker opposes the author's opinion that the decline of the yellow cedar is caused by insect parasites,especially for the cedar bark beetles.Instead,he explains that cedar bark beetles are usually resistant to the yellow cedar because of the toxic chemical inside.So if the beetles cannot suffer the chemical in the yellow cedar,they cannot contribute to the decline of the yellow cedar.Instead,the yellow cedar they attack are damaged and sick.
In addition,the author proposes that the brown bears may be the cause of the decline.However,the speaker casts doubt on it by explaining that yellow cedar trees are all over the place,but there
is decline of the yellow cedar in the place where brown bears do not exist.Therefore,the decline of the yellow cedar cannot be blamed on brown bears as well.
Finally,the speaker suggests that the climate change is not the explanation as well.He explains that in contrast to the explanation in the reading that yellow cedar trees are frozen by the cold climate,yellow cedar trees in the lower areas where the climate is much warmer are more likely to decline unlike the trees in higher places.This proves the climate change theory is also not possible.

Although several anecdotal and a few empirical reports exist,there is a paucity of comprehensive,empirically based research which adequately examines the impact and attractiveness of travel rewards.LaForge noted that intuition is the most common form of measurement for incentive travel satisfaction.

When several people look at the same person, it is not unusual for each of them to see different things; when you are alone observing one behavior or a person at two different times, you may see different things. The followings are but some of the factors that lead to these varying perceptions(感知,认识): (1) Each person’s perceptions of others are formed by his or her own cultural conditioning, education, and personal experiences. (2) Sometimes perceptions differ because of what we choose to observe and how we deal with what’ve observed. It is not necessarily true that person perception is based on observations of a particular person. Your observations may be totally controlled by what others have told you about this person; or you may focus primarily on the situation or role relationship. Most people do not use the same standard to measure their parents, their friends, and strangers. (3) Sometimes we see only what we want to see or don’t see what may be obvious to others because of our own needs, desires, or temporary emotional states. This is a process known as selective perception. Selective perception is obviously more difficult when contradictory information is particularly obvious, but it can be done. We can ignore the stimulus ——“He’s basically a good boy so what I saw was not shoplifting(入店行窃).” We can reduce the importance of the contradictory information ——“All kids get into mischief(顽皮). Taking a book from a bookstore isn’t such a big deal.” We can change the meaning of the contradictory information--- “It wasn’t shoplifting because he was going to pay for it later.”… 小题1:The first factor given by the author that affects our perception is _____. A．our hearing and visual abilities B．cultural background and personal experiences C．the experience one learns from others D．critical measures taken by other people 小题2:While observing a particular person,________. A．one is likely to take all aspects into consideration B．one pays more attention to his/her advantages C．children often differ from grown-ups in perception D．one tends to choose certain aspects to look at 小题3:Observation of the same person by two people at the same time may differ because _____. A．they follow different standards B．either of them may be slow to catch information C．the time for observation is not long enough D．each of them uses different language to express his/her impressions 小题4: The underlined word “stimulus” in Paragraph 4 refers to _____. A．something attractive B．selective perception C．contradictory information D．shoplifting 小题5:The worst thing in selective perception is that ______. A．the information received runs against your desire B．facts can be twisted or totally ignored C．importance of the contradictory information can be overrated (估计过高) D．misbehaved children may not be punished
