microphone-338481_960_720There are lots of voice activated tools and services now available from software on your PC and in your car to physical hardware you can place around your home. These devices are becoming everyday occurrences, “Alexa, whats the weather”, “Siri, recipe for  Chocolate Cake” (too many to list).

The two main ways to control them is via a button press then speaking such as my car to get it into a listening state, or they are always in a listening state awaiting a set of specific interaction commands, such as the applications name. There is at least a turn of listening mode.

However with all these devices and software, there is a distinct lack of security around voice recognition and lack of interaction security. For instance a recent incident where a TV show caused a number of Dolls Houses to be purchased.

We are busy connecting these devices to all sorts of home automation to make it easier to do things, but how many stop to think of what I term as: “The Letterbox Problem”. This is where you have automated your home to a level that includes things like your lights, powered items and your house alarm. As you walk into your house you can say voice commands to turn on lights, put the kettle on and turn off the alarm. The Letterbox Problem happens when someone has the ability to literally shout through your letterbox and activate or deactivate items in your house. To a would be thief, turning lights on and off will check to see if anyone is at home first before going for the alarm.

There is a security challenge here is to ensure that a level of voice recognition and security controls are in place. Voice recognition by itself is not good enough as I’m sure you’ve heard an impressionist mimic a celebrity on a TV or Radio show.

I would like to see a form of two factor authentication on a voice system so it can be sure its me before it carries out the task. Voice may be one of these, but something else like a token code or app on the phone may be a solution.

There a number of basic steps you can take at the moment to help protect yourself such as:

  • Think about the systems you are connecting the voice device to. Can it compromise your security if anyone else uses it.
  • Use the mute button on devices or turn of listening mode when not in use.
  • Keep the devices updated with the latest patches and firmware.
  • Use good password security practices on any sensitive systems you use (ie Bank Accounts, Paypal etc).
  • Use strong passwords on any associated accounts to the voice assistants, (ie Amazon, Google, Apple etc).
  • If your system allows it, clear out its cache and old activities on regular basis so they can’t be replayed against you.
  • Don’t have a system listening when the TV or Radio is on, especially when your out of the room. You may end up with a new dolls house.

 

Digital Tools- Voice Activated Assistants

blogger-336371_640Does the Voice Activated Assistant have a place in the business?   Yes it does. There are lots of voice activated assistants available to help us with our daily tasks. Some are built into mobile devices and some are purchased as specific items. The key is that they all respond to commands and can interact with other devices in our lives.

These devices are already within most business today, but may not being used to their full potential.

“<Insert Name of Assistant> turn on the lights” – providing that the assistant has been linked to the lighting system it will turn on the lights as requested.

Voice programs and activation have been around for along time, but have only recently become more mainstream with the advancements in the speech algorithms and technology to recognise the various dimensions and variants of the human voice. Also the ability to respond in a human voice. Brings back memories of playing around with Dr Spaitso (https://en.wikipedia.org/wiki/Dr._Sbaitso) or watching the film War Games and wanting a talking computer “Would you like to play a game….”.

The biggest market at the moment is the consumer market with devices such as the Amazon Echo being used to connect a myriad of devices and services to build a connected home. There are a number of other assistants out there on devices that can do the same, such as Siri, Cortana, AVIC, and Google Now on the market. There are lots of others available as well.

There are also lots of projects and wishes to have an AI Assistant similar to J.A.R.V.I.S from Marvel’s Iron Man. Such a project is being carried out by Mark Zuckerberg. https://www.facebook.com/notes/mark-zuckerberg/building-jarvis/10154361492931634/

For some having devices around that are constantly listening can be a security issue, however in the main having a voice activated assistants are becoming more common place in every day lives.

“Google says 20 percent of mobile queries are voice searches” http://searchengineland.com/google-reveals-20-percent-queries-voice-queries-249917. This figure will be higher including all the assistants.

This trend is already seeing businesses building web based services to be voice friendly and allow access to data by looking at the type of natural questions someone may ask. Typically a voice search will take longer than a typed search as there is an additional processing step around the voice translation to search, however this is speeding up with the advancements in the programming and algorithms used.

Another example of a business application for voice assistants is where an operator is working with their hands and needs to get a part delivered or get answers to a question about the task they are doing.

In an office the assistant could be used to raise a ticket on the help desk AI, which in turn will try to solve the issue before raising a ticket for a human operator to assist.

Voice has been around for a long time and the future will see it mature to be a more personalised assistant with the ability to interact by recognising the user and have the ability to be called different names, removing the current standard activation names. Linking voice, business systems, data science, AI and machine learning will see a future of being able to ask natural language voice questions to the device about the business/data and obtain a natural language response from the system.
