No matter how advanced computers and software get,
our voices will always be the best communication tool we have. After all, we're born with the innate ability to communicate and, for most of us, talking fast becomes as easy as thinking.
It's no wonder then that the race to develop computers and AI systems capable of interpreting our voices has dominated the focus of large tech companies over the last decade.
But the endeavor to build machines that can listen as well as we can has been going on for far longer than that.
Believe it or not, the first computer able to recognize speech was developed back in 1952 by Bell Laboratories. Adorably nicknamed AUDREY, the machine was breakthrough – even if it could only interpret single digit numbers spoken by one individual!
Voice recognition technology as we know it only really started to gain traction amongst consumers 60 years later with the release of Siri on the iPhone 4s.
Though basic by today's standards, the press and public alike were bowled over by Siri's ability to answer basic questions, perform small tasks, and respond in a natural, conversational manner. For the first time, people felt comfortable talking to an AI.
Naturally, the competition wasn't going to stand still and let Apple take all the glory. Google entered the fray in 2012, releasing Google Now for their Android operating system. Microsoft and Amazon jumped on the bandwagon soon after, unveiling Cortana and Alexa in 2013 and 2014 respectively.
In just a matter of years, voice recognition technology has moved far beyond the smartphone. It's now a standard feature of smartwatches, laptops, games consoles, smart speakers, and more. People aren't just using it to search the web either. They're controlling smart home devices, sending texts and emails, and even making purchases – all with just their voices.
a quarter of U.S. consumers have access to a smart speaker, it's clear that voice-activated technology is here to stay.
How Voice Search Actually Works
The technology and science behind voice search is
Think about it: it's taken millions of years of evolution for our ears and brains to become good at interpreting language, yet computers have been designed to do the same thing in just a few decades.
How does it all work?
To start, the browser collects voice audio from the user via a microphone. This analogue audio file is then converted to digital and sent to a voice recognition software. Here, the file is broken down into phonemes – the smallest building blocks of language – and compared with the software's database of language.
The program then predicts what words are being said, converts them back to text, performs the necessary search, and relays the results back to the user.
When using the
best voice search solutions, all of this happens in the blink of an eye – often before the user has even finished talking.
There's a lot more sciencey stuff going on behind the scenes when you perform a voice search, but that's the nuts and bolts of it!
Voice Search for E-commerce
Buying things with just your voice is an entirely new way to shop, and it's rapidly growing in popularity.
Shopping is the third most popular use of smart speakers
(after playing music and gathering information). Almost
a quarter of voice assistant users say they've made a purchase using the gadget
and Amazon reports that
Alexa use for shopping tripled during the 2018 Christmas period
in comparison to 2017.
There are two key factors contributing to this surge in usage:
Voice shopping is simply faster
than sitting down and searching on a screen-based device. For example, several big supermarkets now have Alexa Skills that allow you to add things to your shopping basket just by asking, greatly accelerating your typically laborious weekly grocery shop.
Voice shopping is barrier-free.
Instead of having to get your phone out of your pocket, unlock it, find an app, and then wait for it to load, voice technology lets you make purchases in mere moments. Limiting the amount of friction between customers and products is a huge benefit of voice shopping.
It's clear to see how voice shopping makes the journey easier for your customers. In fact,
well over half (66%) of smart speaker owners prefer it to visiting a physical store. But how can providing voice functionality on your e-commerce site benefit your business?
Voice shopping is perfect for cross-selling.
Because voice is such a natural, relaxed way of interacting, customers are far more likely to take you up on a special offer or product recommendation. Picture the scene: you're about to finalize your weekly shop order when the voice from your Alexa says, “Would you like to try our new chocolate cheesecake – it's just
$1 with this purchase.” Would you say no? Of course you wouldn't!
Voice shopping helps you personalize the customer journey.
You can glean a lot of information from how your customer sounds. Are they male or female? Young or old? All this data can help you provide them with a more personalized, tailored shopping experience that's sure to keep them coming back for more.
While making purchases with your voice is so seamless that it could deter more cautious consumers, it's easy to see how the trend of voice shopping will continue to grow in popularity – especially with younger generations, who are
adopting voice technology at a faster rate than their older counterparts.
Voice Search for Marketing
Voice search has huge potential as a marketing tool, though the rules of the game differ greatly from traditional online campaigns.
To start with, neither of the big branded voice assistants (Google Home/Amazon Alexa) allow for paid advertising on their platform. This is for good reason: advertising would dissuade people from adopting the technology and erode the fragile trust these companies have worked so hard to construct.
One way around this is to instead
focus your voice-led marketing efforts on brand-building.
It's easy to create Alexa Skills and Google 'Actions' to engage with audiences in new and interesting ways.
There are many examples of this done well. Take fabric care brand Tide, for instance. Their
'Stain Remover' skill for Alexa
lets users ask for specific stain removal advice and receive step-by-step instructions (involving Tide products, naturally.)
One drawback of taking this route is that it requires a lot of hard work. Creating an Alexa Skill or Google Action is fairly straightforward, but the challenge lies in making it reliable and functional enough for people to want to use time and time again.
no playbook on voice app best practice
due to the technology's infancy, making designing one and measuring its success a fair amount of guesswork.
Skills and Actions may not have the same sales-charging clout as direct online advertising, but, like social media channels, they're an excellent way of building brand personality, recognition, and trust.
The other marketing angle to take with voice search technology is to play the ol' SEO game. Unlike searching for answers on a device with a screen, voice search devices only provide users with the top search result as opposed to a list of several. This means that it's never been more important to SEO-optimize your content to boost it to the SERP's top spot.
Voice search for marketing is clearly still finding its feet, but – as with all new endeavors – there are plenty of rewards to be reaped by businesses willing to dip their toe in the water. Follow these tips to give your voice marketing efforts the best chance of success:
Focus on getting your brand heard
The first goal of voice search for marketing is to
use the technology to build awareness.
This could be achieved by creating a fun game, a Buzzfeed style quiz that tells you what type of wine you'd most enjoy, or a chatbot that suggests playlists based on your mood – the options are practically limitless, so have fun, be creative, and drum up interest in your brand!
Keep it natural
It's crucial from a usability and an SEO perspective to keep your voice search results and applications sounding
conversational, straightforward, and generally helpful.
Answering direct questions succinctly in your content is also key, with a large majority of voice search queries being explicit questions.
Use a custom search engine that offers voice capabilities
As more and more e-commerce and content websites offer voice search, users will come to expect this functionality as standard.
Don't allow your website to be left behind. Investing in a site search solution that is capable of offering
voice search will futureproof your website
against the voice-first revolution.

Challenges of Voice Search
As with any new piece of tech on the block, there are several teething problems companies must overcome if they want voice search to penetrate the mass-market.
Have you ever mentioned to a friend, in person, that you're thinking about booking holiday only to find your Facebook feed full of travel adverts?
It's downright creepy.
Facebook has stated countless times that they '100% do not listen to our conversations
', but can they really be trusted when they've been caught up in
so many privacy scandals?
Nobody wants to be spied on and in a world where Google, Facebook, and Apple already know more about us than we do, allowing tech companies to listen in on our conversations is a bridge too far for many consumers.
79% of people are concerned about the privacy implications of using voice search devices. And new generations are becoming increasingly aware of these issues, with the youngest voice searchers (13-21) being
515% more likely
than the oldest (65 or older) to feel very concerned about voice search and privacy.
If voice search is going to become more prevalent, tech companies must do more to quell consumers' concerns and become more transparent about how our voice data is being used, processed, and stored. Google has already made a good start, allowing users to
delete any voice clips captured, but more still needs to be done to build trust with consumers.
Voice is still finding its feet on desktop
Although both Windows PCs and Apple Macs both feature Cortana and Siri respectively, web browsers themselves still mostly lack voice search functionality. Google Chrome is, so far, the only web browser with voice search built-in.
Until voice search is available on every device and every browser, the tool will struggle to become a ubiquitous means of searching the web.
Language support and regional accents
While voice recognition has become pretty decent at understanding American and British English accents, most solutions still fall far short of the mark when it comes to recognizing other languages and regional accents.
This is not only an annoyance: there's a fear that certain languages,
like Icelandic, could be facing digital extinction thanks to the English language's domination of the internet.
There's no doubt that as voice recognition databases continue to collect more regional data samples this will improve eventually. Still, it's currently a genuine issue that's stopping people with stronger accents investing in voice search devices.
A major hurdle still hindering voice search's rise to prominence is simply the fact that it still occasionally struggles to hear what users ask for.
Why go through the effort of talking to your search box if it only works three-quarters of the time?
Here are some of our favorite examples of voice searches gone wrong:
Voice recognition software has come a long way, with Google claiming to have
achieved 95% word accuracy and
reduced errors in speech recognition by 29%. But, overall, it's still far from being perfect.
Voice recognition needs to be 99% reliable if it's ever going to overtake screen-based search.
Is Voice the Future of Search?
There have been many outlandish predictions about voice search over the past few years:
“50% of searches will be voice searches by 2020” (yeah, right);
“By 2020, 30% of web browsing sessions will be done without a screen” (keep dreaming);
“Voice shopping is set to jump to
$40 billion by 2022” (*spits out coffee*)
The fact is no one can predict the future with any accuracy. If you'd told us 20 years ago we'd one day be telling machines to turn up our heating and lock the back door, we wouldn't have believed you – yet here we are.
What we can say for certain, however, is that so long as the technology and voice recognition software continue to improve, voice search will one day be as common as searching on a screen.
