Voice search for multiple platforms

Voice search API for voice assistants and mobile devices.
  • Smart voice assistants

    If your company has an Amazon Alexa skill or Google Assistant action, our voice search capabilities can improve them. Instead of forcing your users to make endless decisions about what they want, you can let them search by voice and get immediate, accurate results from our advanced voice search functionality.

  • Mobile devices

    We provide voice search for both mobile apps and mobile websites. 

    The most common use of voice search is not with smart speakers but on mobile devices such as Apple iPhones (using Siri) and Android phones. More than half of voice searchers are speaking voice commands on their mobile devices every day. They’re looking for information about events on social media, or they're doing local searches, such as for local businesses that carry a product they want. Twenty percent of all searches being done on mobile devices are by voice, so it pays to optimize for this type of search.

Voice search FAQs

  • People are searching by voice more and more. While voice search was not something many people did five years ago, with the improvement of speech recognition on iOS, Android, and the web, voice search has taken off on all of these platforms. The trends all point to the same thing: if businesses provide a voice input option on the search bar in their apps and on websites, people will take advantage of it.

  • The best voice search technology gives users and customers the ability to search by voice with natural language or keyword queries. This opens up more interactive opportunities when people are on the go, taking public transportation, or simply have their hands full. To best serve these types of voice searches, it is important to have technology that can understand what people are saying and personalize the results for them.

  • Not only does voice search facilitate accessibility, it can be more convenient than typing, especially on platforms such as mobile or smart television, where typing can be error prone or a hassle.
