Voice search: what is it and how does it work in e-commerce?

This is possible through artificial intelligence speech recognition. Understand what it is and how this innovative technology works.


A voice search is gaining more and more space in search engines, websites in general and even in e-commerce, as it provides much more convenience and accessibility for this task.  

Taking the necessary precautions, voice search on search engines can help drive more traffic to the site; and when present within virtual stores, it allows customers to find products more easily, especially those that are in doubt as to the correct spelling.

In both cases, the purchase journey becomes much faster, more assertive and practical. Therefore, we prepared this content to explain everything that involves this technology. 

What is voice search?

A voice search is a feature that allows users to search for information on the internet or within a specific website using only their voice, without having to type anything in the search field

A voice technology it is increasingly common to do all types of searches on search engines, like Google and Bing; to perform commands on Smart TVs, such as turning on and off, switching channels, searching for movies and series; and to do both with the voice assistants Alexa, Google Home, Siri, Cortana, etc. 

How does voice search work? 

Voice search works through the speech recognition com artificial intelligence (AI) and is only possible thanks to the union of two fields of study: linguistics and computing, which gave rise to the computational linguistics.

With speech recognition, AI is able to identify verbally pronounced phonemes, words and phrases. In this way, it is possible to promote speech interaction of the human being with the machine. 

How to leverage voice searches to increase website traffic

In a scenario where voice searches are increasingly on the rise, optimize your website pages to be found in voice search results is a way to increase your organic traffic generation. Check out some tips that will help with this.

  • Bet on long-tail keywords
  • Enter questions and answers
  • Use more informal language

Bet on long-tail keywords

Users tend to search differently when they use voice search. While in written mode people usually type single words and often more general terms such as “e-commerce in Brazil” or “jeans”, in voice search, searches are more specific and long-tail keywords are more common. For example: “size 36 skinny jeans”.

Enter questions and answers

Another way to perform voice searches is by asking questions, such as: “does the clothes dryer use a lot of energy?”. Therefore, you can take advantage of and use these questions and answers to compose your e-commerce product pages or even create content for your company's blog. 

Use more informal language

Spoken language is much more informal than written language, so in order for your website pages to appear in search engine results, keep your website communication in a more informal tone — but without letting it get in the way of understanding and always taking into account your persona.

Voice technology and accessibility

Voice technology is closely related to accessibility for people with visual impairments, disability or absence of hands and arms and even the illiterate public. In addition, it also facilitates the search for items with foreign words and/or difficult spelling, which we sometimes know how to speak but cannot write. 

So, in addition to helping to generate organic traffic, optimizing your site for voice searches also make your more inclusive company.

Voice search in online stores

Voice search for e-commerce works more or less in the same way as voice search for search engines, only within the virtual store. And it acts as a complementary strategy to optimizations to appear in search engine voice searches.

It is one of the features of smart search, which uses artificial intelligence to optimize online searches. Therefore, it has the same characteristics: high speed; phonetic similarity; automated color search, through image recognition; is behavioral search. And it works on both desktop and desktop computer. smartphone

This means that if the consumer chooses to use his voice, he will have access to the same advantages of typed research, but with a plus: the convenience of not having to use his hands to type. 

How it works

In cases of voice search for e-commerce, the consumer just needs to click on the microphone icon, speak what he wants and the intelligence will identify what was said and transcribe it into text automatically, as shown in the example below:

As mentioned earlier, note that the other capabilities of smart search also work on voice search. Therefore, it was possible to find the product by searching by color — even without having this information in the title or description of the product — and the results were shown in milliseconds.  

Likewise, if the customer mispronounces the name of a product or a brand, the intelligence identifies the information and the voice search shows the right results, similar to what happens with the search typed in a smart search. It's a great outlet for foreign products and brands with names that are difficult to spell and/or pronounce. See the video below to see how it works.

In the previous example, the consumer is looking for a specific type of wine, “pinot noir”, a grape originally from France. Anyone who knows a little about the French language knows that the correct pronunciation makes the word “pinot” sound stronger in the second syllable, that the “t” is almost silent and that the “go” of “noir” has a sound similar to “arr” for Portuguese speakers. 

But who does not know this, ends up pronouncing it as if it were a word in the Portuguese language. However, as you have seen, voice search has the ability to identify and show the right results nonetheless.
