Voice search refers to the use of spoken commands or questions to search for information on the internet or other digital devices. Instead of typing a query into a search engine, users can simply speak their request, and the device will use speech recognition technology to interpret the command and provide relevant search results.

Voice search technology has become increasingly popular with the widespread use of digital assistants like Amazon's Alexa, Google Assistant, and Apple's Siri. These assistants are integrated into various devices such as smartphones, smart speakers, and other smart devices, allowing users to control their devices and search for information hands-free.
