The next time you try for a high-ranking post,you could let your possible boss listen to a recommending(推荐)phone call "made" by US President George W．Bush or British Prime Minister Tony Blair．
Of course ,neither of them could really do that for you--you would just "borrow" their voices．
AT & T labs will start selling speech software that it says is so good at reproducing the sounds of a hmnan voice that it can recreate voices and even bring the voices of long-dead famous people back to life．
The software, which turns printed text into speech, makes it possible for a company to use recordings of a person' s voice to say things that the person never actually said．
Possible customers for the software, which is priced in the thousands of dollars, includes telephone call centers, companies that make software that reads digital (数字的)flies aloud, and makers of automated voice devices(装量)．The advances raise several problems．Who ,for example, owns the rights to a famous person's voice? Some experts even believe that new contracts(合同) will be drawn that include voice-licensing clauses．
And although scientists say the technology is not yet good enough to commit fraud (假冒), would the synthesized (合成的)voices at last be able to trick people into thinking that they were getting phone calls or digital audio recordings from people they know?
Even Mr．Fruchterman,one of AT & T labs' possible first customers,said he wondered what the new technology might bring．"Just like you can't trust a photograph any more．" he said,"you won't be able to trust a voice either．"
If the speech software were widely used,_______．
推理判断题。这种软件可以模仿人们的声音，可以说出人们事实上未说过的话，因而在法庭上是不能作为证据的。
把10gMgCl2和MgSO4的混合物溶于适量水中，滴加2mol／L的BaCl2溶液至沉淀完全，共消耗BaCl2溶液25mL。求混合物中MgCl2和MgSO4的质量各是多少克
固定在匀强磁场中的正方形导线框abcd，各边长为1．其中ab是一段电阻为R的均匀电阻丝，其余3边均为电阻可忽略的铜线。磁场的磁感应强度为B，方向垂直纸面向里。现有一与ab段的材料、粗细、长度都相同的电阻丝PQ架在导体框上，如图所示。PQ以恒定速度方向如何
