28、 a magic spell,it lets people control the worldthroughwordsalone.Any sufficientlyadvancedtechnology,noted ArthurC.Clarke,a Britishscience-fiction writer,is indistinguishablefrommagic.Thefast-emergingtechnologyof voice computingproves his point.Usingit is just like castinga spell:say a few wordsintot

30、about 4%of Americanhouseholds.Voice assistantsare proliferatingin smartphones,too:Apples Siri handles over2bncommands a week,and20%of Googlesearcheson Android-poweredhandsets in Americaare inputbyvoice.Dictatingemails and text messages nowworksreliably enoughto be useful.Whytypewhenyoucantalk?CThisi

31、s a huge shift.Simple though it may seem,voicehas the power to transformcomputing,byprovidinga naturalmeansof interaction.Windows,icons and menus,and thentouchscreens,were welcomedasmoreintuitive ways to deal withcomputersthanenteringcomplex keyboardcommands.Butbeing able to talktocomputersabolishes

32、 theneed fortheabstraction of a“user interface”atall.Just as mobile phonesweremorethanexisting phones withoutwires,and carswere more thancarriageswithouthorses,so computerswithoutscreensand keyboardshave thepotentialto be moreuseful,powerfuland ubiquitousthanpeoplecanimaginetoday.DVoicewill notwholl

33、y replaceotherformsof inputand output.Sometimesit will remainmoreconvenientto converse witha machinebytypingratherthantalking(Amazonis said to be workingon anEchodevice withabuilt-inscreen).Butvoiceis destined to accountfora growingshareof peoples interactionswiththe technologyaround them,fromwashin

34、gmachinesthattell you how muchof the cycle they have left to virtual assistantsincorporatecall-centers.However,to reachits full potential,the technologyrequires furtherbreakthroughsandaresolutionof thetrickyquestions it raisesaround thetrade-offbetween convenience and privacy.EAlexa,what is deeplear

35、ning?Computer-dictationsystems have beenaround for years.But they wereunreliable andrequiredlengthy trainingto learn a specific users voice.Computers new abilityto recognizealmost anyones speech dependablywithout trainingis the latest latest manifestationof the power of“deeplearning”,an artificial-i

36、ntelligence technique in which a softwaresystem is trained using millions of examples,usually culled(挑 选)from the internet.Thanks to deeplearning,machines now nearly equalhumans intranscriptionaccuracy,computerizedtranslationsystems are improving rapidly andtext-to-speechsystems arebecoming less rob

37、otic and morenatural-sounding.Computersare,in short,gettingmuchbetter athandling naturallanguagein allits forms.FAlthough deep learning means that machines can recognize speech more reliably and talk in a lessstilted(不自然的)manner,they still dont understand the meaning of language.That is the most dif

38、ficult aspect ofthe problem and,if voice-driven computing is truly to flourish,one that must be overcome.Computers must beable to understand context in order to maintain a coherent conversation about something,rather than justresponding to simple,one-off voice commands,as they mostly do today(“Hey,S

39、iri,set a timer for tenminutes”).Researchers in universities and at companies large and small are working on this very problem,building“bots”that can hold more elaborate conversations about more complex tasks,from retrieving information toadvising on mortgages to making travel arrangements.(Amazon i

40、s offering a$1m prize for a bot that can converse“coherently and engagingly”for 20 minutes.)GWhen spells replace spelling.Consumers and regulators also have a role to play in determining how voicecomputing develops.Even in its current,relatively primitive form,the technology poses a dilemma:voice-dr

41、ivensystems are most useful when they are personalized,and are granted wide access to sources of data such ascalendars,emails and other sensitive information.That raises privacy and security concerns.HTo further complicate matters,many voice-driven devices are always listening,waiting to be activate

42、d.Some people are already concerned about the implications of internet-connected microphones listening in everyroom and from every smartphone.Not all audio is sent to the clouddevices wait for a trigger phrase(“Alexa”,“OK,Google”,“Hey,Cortana”,or“Hey,Siri”)before they start relaying the users voice

43、to the servers thatactually handle the requestsbut when it comes to storing audio,it is unclear who keeps what and when.IPolice investigating a murder in Arkansas,which may have been overheard by an Amazon Echo,haveasked the company for access to any audio that might have been captured.Amazon has re

44、fused to co-operate,arguing(with the backing of privacy advocates)that the legal status of such requests is unclear.The situation isanalogous(相 似)to Apples refusal in 2016 to help FBI investigators unlock a terrorists iPhone;both caseshighlight the need for rules that specify when and what intrusion

45、s into personal privacy are justified in the interestsof security.JConsumers will adopt voice computing even if such issues remain unresolved.In many situations voice isfar more convenient and natural than any other means of communication.Uniquely,it can also be used whiledoing something else(drivin

46、g,working out or walking down the street).It can extend the power of computing topeople unable,for one reason or another,to use screens and keyboards.And it could have a dramatic impact notjust on computing,but on the use of language itself.Computerized simultaneous translation could render the need

47、to speak a foreign language irrelevant for many people;and in a world where machines can talk,minor languagesmay be more likely to survive.The arrival of the touchscreen was the last big shift in the way humans interact withcomputers.The leap to speech matters more.36.Despite the issue of invasion o

48、f privacy,voice-computings irresistible convenience is already receivingwide adoption.37.Conventional forms of input and output will not be entirely replaced by voice command.38.Deep learning revolutionizes speech technologies,enabling computers to process any natural language.39.Screens and keyboar

49、ds of computers are not necessarily indispensable because of the invention of voicecomputing.40.Deep learning has real successes,but is not enough to understand the meaning of language.41.The convenience brought by voice computing can come at a risk of privacy or security.42.Laws that apply to priva

50、cy and security issues for voice technology are needed in light of the two cases inAmerica.43.Despite its simple appearance,voice is capable of changing computing,by bypassing the physical realm.44.Thanks to voice computing,several devices such as smartphones have already done some tasks by voiceord
