哪位 帮我翻译一下:
Because speech is the most convenient form of communication, in the future we want essentially natural conversations with computers. The primary point of contact will be a simple device that will act as our window on the world. You will simply talk to it. The device will be permanently connected to the Internet and will beep relevant information up to you as it comes in.Just how quickly people will adapt to a voice-based Internet world is uncertain. Many believe that, initially at least, we will need similar conventions for the voice to those we use at present on screen: click, back, forward, and so on. But soon you will undoubtedly be able to interact by voice with all those IT-based services you currently connect with over the Internet by means of a keyboard. This will help the Internet serve the entire population, not just techno-freaks.Changes like this will encompass the whole world. Because English is the language of science, it will probably remain the language in which the technology is most advanced, but most speech-recognition techniques are transferable to other language provided there is sufficient motivation to undertake the work..

第二篇Credit Card Only Works When Spoken ToA credit card that will not work unless it hears its owner's voice could become an important weapon in the fight against fraud（欺骗）.The card requires users to give a spoken password that it recognizes using a built-in voice-recognition chip.The idea is to prevent thieves using a stolen card or fraudsters using someone else's credit card details to buy goods online.A model built by engineers at Beepcard in Santa Monica,California,represents the first attempt to pack a microphone,a loudspeaker,a battery and a voice-recognition chip into a standard-sized credit card.They are not quite there yet:the card is the length and width of an ordinary credit card, but it is still about three times as thick.The company now plans to make it thinner.The voice card is based on an earlier Beepcard technology designed to prevent fraud in online transactions.This earlier card has no microphone,but has a built-in loudspeaker that it uses to " squawk"（发出叫声）a voice ID signal via a computer's microphone to an online server.By verifying（证实）that the signal matches the card details,the server can establish that the user is not simply keying in a credit card number but actually has the card to hand. The ID code changes each time the card is used in a pre-ordered sequence that only the server knows.This prevents fraudsters recording the beeps, noting the card details and then playing back the audible ID when they key in the details later.But this earlier technology cannot prevent fraudulent use of stolen cards.The new one can.The new voice card also identifies itself by its ID squawk,but it will not do this until it has verified the legitimate（合法的）user's spoken password. Thieves will be unable to use the card because even if they knew the password they would have to be able to copy the owner's voice with a high degree of accuracy.The challenge for Beepcard has been to develop voice-recognition and audio circuitry that can be powered by a mini battery embedded（嵌入的）in a credit card. To maximizebattery life,the electronics are only switched on when the card is being used.Pressing a button on the card's surface prompts it to utter "Say your password" in female voice.If the voice-recognition software proves that the password is authentic（真实的）,it sends its IDsquawk which the server then identifies,allowing the transaction to proceed.What can we learn from the last paragraph about the voice card?A:Only female voice passwords could be recognized.B:Further improvement should be made to extend battery life.C:There is no!imit to its application.D:Female customers like to use it.
