These companies say the tools can also detect fraud, screen airline passengers and help a call-center technician better deal with an irate customer. And they can be used to keep tabs on employees or screen job applicants. One developer, Tel Aviv-based Nemesysco Ltd., offers what it calls 'honesty maintenance' software aimed at human-resource executives. The firm says that by analyzing a job applicant's voice at an interview, the program can help identify fibs.

这些公司说，这些工具还可以侦测欺诈、检查飞机乘客、帮助呼叫中心技术人员更好地对付发飙的顾客。它们可以用来监视员工或筛选求职者。特拉维夫开发商Nemesysco Ltd.推出以人力资源经理为目标客户的“诚信维护”软件。该公司说，这套程序可以通过分析求职者在面试期间的说话声音来帮助辨别谎言。

That's raising alarm among many voice-analysis experts, who question the accuracy of such on-the-spot interpretations. It's also raising worries among privacy advocates, who say such technology -- especially if it is being rolled out in cheap, easy-to-use smartphone apps -- could be a fresh threat to privacy.

这引起了很多语音分析专家的警惕，他们对这类现场转译的准确性提出了质疑。也引起了很多隐私鼓吹者的忧虑，他们说，这类技术有可能成为一种新的隐私威胁，如果是以便宜好用的智能手机应用的形式推出，威胁就更为严重。
