#科技头条#【可以检测场景的语音助手:如果Siri和你窃窃私语】人工智能语音助手正在改变我们的生活,人类越来越无法阻止Siri了。一项专利显示,苹果公司计划开发一种语音助手技术,可以称之为“耳语语音助手”。耳语助手不仅可以识别内容,还可以检测到你在是否在窃窃私语,从而知道什么时候要悄悄地话。比如,在格子间里工作或在图书馆学习,耳语检测功能都可以派上用场。不过,目前尚不清楚苹果公司何时或是否计划推出这项技术的应用。

Shhh Siri! Apple is developing a voice assistant that can detect when you're whispering and know when to whisper back, patent suggests

  • A patent filed by Apple in 2016 for the technology has now been granted 
  • The technology would allow Siri to detect when you are whispering 
  • The digital assistant would respond accordingly and whisper back to you  
  • It would recognise amplitude and frequency of the voice and analyse the tone

Apple has identified that sometimes you can't talk to your phone in a loud, clear voice and that certain situations may require a little more delicacy.

A patent has revealed Apple's plans to develop a voice assistant that can detect when you're whispering and know when to whisper back.

It is unclear when, or if, Apple plans to launch the technology.

HOW WOULD IT WORK?

The patent states a need to be able to recognise when people are whispering.

Designed to be used in situations where talking at a regular or loud volume is not possible  such as in a public library or at work.

It would recognise the subtleties of speech and respond back to you in a whisper as well.

The patent, titled 'Digital Assistant Providing Whispered Speech' was first filed in 2016 and was published last week.

Apple states in the patent that there is a gap in the market for 'a digital assistant that is capable of detecting a whispered speech input and providing a whispered speech response.'

It describes scenarios where whispering to your smartphone companion is necessary and how it will adapt to understand and whisper back.

For example, working at a cubicle near co-workers or studying in the library are listed as examples of when the whisper detecting function would come in handy.

The document says: 'Some existing speech recognition devices may be incapable of detecting user's whispered speech, or suffer from misrecognition of the whispered speech.

'Nor are they capable of responding to the user using a whispered speech.'

Alex Rudnicky, a professor at Carnegie Mellon University's Language Technologies Institute, told Gizmodo: 'I can't really say why nobody's come up with this solution.

Frequency and amplitude are vital measures for the detection of speech, currently whispers can not be accurately or consistently detected 

The patent outlines a way to make whispers understandable for the device and then to respond with a whisper as well.  Encouraging the technology to better replicate the subtleties of human conversation

'But once you hear it, it sounds really reasonable. Why not?'

The basic principle of the outlined technology is the ability to analyse the amplitude and frequency of the users voice.

It will then compare the voice data to other known tones of voice and reply accordingly.

The patent would expand the use of the feature into trickier environments and widen the scope and use of voice recognition.

Although the patent filing does signal some level of interest from Apple in the technology, it's not a certain that it will be incorporated into their devices.

Apple, along with several other large companies, file patents for new technology all the time in an attempt to protect it for the future.
