参考答案：B

参考解析：

推理判断题。根据第二段第二句“At this year’s I/O Conference, a company showed a new voice technology able to produce such a convincing human-sounding voice that it was able to speak to a receptionist and book a reservation without detection.（这项语音技术可以产生一个听起来和人类非常相似的声音，它可以和接待员进行交谈，进行预订。）”可知，这项新技术有其好的方面；再根据第三段可知，欺诈者们可以利用这项新技术来进行欺诈行为。由此推知，这项新技术既可以发挥好的作用，也可能为坏人所利用，产生不好的影响，因此可以说它是一把双刃剑。故选B。
