SAN FRANCISCO， Aug. 24 (Xinhua) -- Results from an experiment suggest that speech recognition， in case of composing text messages on smartphone， can be faster and more accurately than humans can type on phone screens.
The experiment by researchers from Stanford University， Baidu Inc. and the University of Washington brought in 32 texters， ages 19 to 32， to work the built-in keyboard on an Apple iPhone against Baidu's Deep Speech 2 cloud-based speech recognition software.
"They grew up texting， so we're putting speech recognition up against people who are really good at this task，" James Landay， a professor of computer science at Stanford and co-author of the new study published online at arXiv.org， was quoted as saying in a news release from Stanford on Wednesday.
The subjects took turns typing or speaking about 100 phrases sourced from a standard library of everyday phrases used in text-based research - phrases such as "physics and chemistry are hard，" "have a good weekend" and "go out for some pizza and beer" - while the testing app recorded their times and accuracy rates. Half the subjects performed the task in English using the QWERTY keyboard; the other half conducted the test in their native Mandarin Chinese using Apple iOS' Pinyin keyboard.
"Speech recognition is something that's been promised to us for decades， but it has never worked very well，" Landay said about the experiment. "But we were noticing that in the past two to three years， speech recognition was actually improving a lot， benefiting from big data and deep learning to train its neural networks to produce faster， more accurate results. So we decided to formally test it against humans."
The results: for English， speech recognition was three times faster than typing， and the error rate was 20.4 percent lower; in Mandarin Chinese， speech was 2.8 times faster， with an error rate 63.4 percent lower than typing.
"We knew speech recognition is pretty good， so we expected it to be faster， but we were actually quite surprised to find that it was almost three times faster than typing on a keyboard，" said co-author Sherry Ruan， a computer science PhD student at Stanford who helped run the experiments.
Although only the speech recognition software from Baidu， a web services company headquartered in Beijing， China， and listed on NASDAQ Stock Market in New York， the United States， was used， the researchers suspect that other high-accuracy speech engines perform at a similar level and they hope that given the results of their experiment， engineers will be encouraged to design user interfaces that take better advantage of the speech recognition technology.
"We should put speech in more applications than just typing an email or text message，" said Landay.
BEIJING Cheap Nike Air Max 97 OG Silver Bullet , July 3 (Xinhua) -- Chinese netizens, never lacking in self-mockery, have found a new way to greet would-be freshmen who are busy filing college applications.
"Never join our university because you will find that we have air conditioning in the morgue but not in the dorms, which is beyond imagination Cheap Men's Nike Air Max 97 Ultra'17 Pink Blush Shoes ," said Weibo user "guiyizhangchudashao" from Shandong University of Traditional Chinese Medicine.
As many universities try to project their best image in this round of "students rush," comments from insiders provide a different view from the usual official promotion brochures.
"Never join our university because the campus is like a zoo: we have seen not only cats and dogs, but also deer, peacocks and owls!" said one netizen identified as a student from Southwest Jiaotong University.
Majors are also a topic of this wave of online self-deprecation. "Never join the major of archaeology because nobody understands what you are learning Cheap Men's Nike Air Max 97 UL'17 HAL Black ," said a placard held by a young lady in an online photo.
Other netizens followed her example by wearing written placards reading "never join the English major because too many girls here render you little chance of finding Prince Charming" or "never join the major of preschool education because you will become mentally and physically exhausted taking care of children."
Some also joked that their majors do not live up to the impression their names give. "Our work has nothing to do with 'international,' 'trade,' nor 'international trade,'" said another placard.
Most freshmen said they never consider such "advice" very seriously.
"When making decisions Cheap Nike Air Max 97 UL '17 SE Black , I think it is more important for us to follow our own hearts and choose what we really like," said He Li, a high school graduate from Hebei Province.
Zheng Tingxuan from Shanghai, who has applied for Jilin University Cheap Off-White x Nike Air Max 97 Virgil Abloh White , said he cares more about college academic quality rather than the conditions of dormitories or the cafeteria.
However, some have been influenced by others' opinions. Wu Chengjie, the top scorer in science in the national college entrance exam for Jiangsu Province, has changed his mind on his subject of study.
"All the reporters that have interviewed me advised me not to choose journalism Cheap Men's Nike Air VaporMax 2.0 Tan Cream , so now I am considering finance," said Wu.
According to the Ministry of Education (MOE), 9.39 million applied for this year's national college entrance exam, and another 7.27 million university graduates will enter the job market in 2014. The prospect of landing a good job has become a main consideration in college applications and choosing a major.
