Understanding voice search technology and using it for online marketing

People search for content online. A trade association survey at the end of 2021 showed that most shoppers prefer to get information on Google. 76 percent of respondents take a look at Google first when searching for a product. But Google searches can be different. Quite classically, search queries (keywords) can be typed into the search engine, but innovations such as voice assistants (Siri, Alexa, etc.) mean that searches can also be conducted via voice search. This type of search is called Voice Search referred to. 


What is Voice Search?

Voice Search is a technology that enables users to search the Internet for information by voice.. Voice assistants enable users to find answers to their questions quickly and easily. Voice assistants are not only available on mobile devices (smartphone), but also on computers or other smart devices as for example Amazon Alexa. 

Voice search is nothing new; the technology has basically been around since 2011, when Google publicly communicated that voice search was possible. Of course, the technology has developed considerably since 2011. Currently, Google achieves an accuracy of 95% for queries.

How does Voice Search technology work?

The task of the technology behind Voice Search is to transfer natural language into a machine-readable format. This is done using methods such as machine learning, artificial intelligence (AI) and natural language processing (NLP). . In this context, the focus of NLP is on the interaction between humans and machines. In voice search, NLP is considered a subarea of artificial intelligence, because human speech is decomposed into individual words in order to subsequently generate a semantic context to recognize. The purpose of this is that very complex search queries can be understood and also correctly classified.

For those who want to know exactly - these analyses are taken into account:

  • Speech recognition: The spoken text is transmitted to the device (mobile, computer, etc.) via the microphone and transformed into a text string. 
  • Lexical analysis: The text chain is broken down into meaningful words and sentences. 
  • Morphological analysis: The text is examined for grammatical structure. 
  • Semantic analysis: The context of the text is grasped and thus acquires meaning. 
  • Pragmatic analysis: The function of the text is determined, for example whether it is a statement or a question. 

This analysis makes it possible for search engines to display appropriate search results for voice queries.

Like the search engine itself, voice search takes into account local and personal preferences. Depending on where the user is located, the search results for one and the same search term can vary. By evaluating the voice, a new possibility arises in the selection of suitable search results for the respective user. Through Voice analyses Google takes into account criteria that enable highly personalized search results. For example, if a user searches for the keyword "shoes" using voice search, the voice analysis tools allow the voice to be classified as female or male. Through this analysis, the search engine delivers personally suitable search results for the respective user. 


What voice providers are there?

Siri (Apple)

Siri from Apple was the pioneer of voice providers in 2011, so to speak. As with all new technologies, there were initial difficulties, but the technology has improved enormously. Siri is available on Apple products like MacBooks, iPads, iPhones, iWatch, etc. 

Google Assist

The Google Assistant answers questions and executes commands. The assistant offers a simple way to operate smartphones and also other apps via voice command. Google Voice Search was released in 2011. Since 2012, there is also an app for mobile devices. 

Alexa (Amazon)

We know from Amazon that they always want to be at the forefront quickly. Thus, Amazon has also quickly found a connection to voice technology: The smart device Alexa for your own 4 walls. Meanwhile, the Echo speaker is the market leader among smart speakers. 

Cortana (Microsoft)

Of course, Microsoft also wanted to be in on the action - the voice assistant Cortana is included by default starting with Windows 10. 


How is search behavior changed by voice search? 

Users search differently via voice than via text-based search. Spoken search queries through tools are usually longer because searchers formulate complete sentences instead of individual search terms. The use of mobile devices is increasing and so is the use of voice search.
