Voice search, also called voice-enabled search, allows the user to use a voice command to search the Internet, a website, or an app.
In a broader definition, voice search includes open-domain keyword query on any information on the Internet, for example in Google Voice Search, Cortana, Siri and Amazon Echo.
Voice search is often interactive, involving several rounds of interaction that allows a system to ask for clarification. Voice search is a type of dialog system.
Voice search is not a replacement for typed search. Rather the search terms, experience and use cases can differ heavily depending on the input type.
