2017 is shaping up to be the year of the digital assistant.

Devices featuring voice recognition digital assistants took CES by storm this year. Intelligent, voice activated digital assistants abound. Amazon has Alexa, Microsoft has Cortana, Apple has Siri and Google has… well, Google.

Amazon’s Alexa stole the show as it seems to have gained first mover advantage by not only featuring successfully in the popular Amazon Echo device, but also being the voice recognition system of choice for other companies producing everything from media streaming to fridges.

I think people are just waking up to the possibilities for – and dangers of – this technology.

We were amused by the story of a 6 year old girl using Alexa in her parent’s Amazon Echo to order herself a dolls house. When the news was reported on local TV in San Diego, the words spoken by the newscaster triggered other Amazon Echoes within earshot of tuned-in TVs to perk up and attempt to do the same. Ooops.

The trouble is – that’s how easy it can be to voice activate these digital assistants. They hear their trigger phrase (or think they hear it) and off they go. I’ve often seen my Google phone activate when it thinks it hears me talking about the Google Assistant (normally using the words, “OK Google” as part of a wider conversation on the topic).

"People are just waking up to the possibilities for – and dangers of – this technology."

Should we be concerned about this?

Maybe. You may or may not know that Google already records and retains all your Google activity. This includes keeping an audio transcript of everything you say whenever you activate Google’s digital assistant. Alexa does the same thing. You can review and delete these messages, but they are there.

You can see your Google audio transcripts by visiting https://myactivity.google.com and filtering the content to “Voice & Audio”.

When we tried this, we found that many snippets of conversations had been captured and could be replayed at the touch of a button. This included personal or work related conversations that could have included sensitive material. Try it yourself, it’s a little unnerving.

We’re not discussing anything nefarious here – but why does this make me uneasy? The thing is, these tech firms say they need to capture and retain this content to help fine tune the accuracy of their digital assistants. Maybe…but still.

On that note, whilst Alexa is the star of this year’s CES event, newly arriving Google Home (not yet available in the UK) may yet win the race. The search giant may be a late comer to the personal assistant device party but it’s own Google Assistant should, on paper, have access to a wider range of information than Amazon.

If only it had a more personal name than “Google”. My bet is that it will sooner than we think.
