Cortana, Siri, and Alexa all use Bing rather than Google as their default search engine. Here’s how to get around this restriction.
Change CORTANA Assistant Using BING
You can make Cortana use Google rather than Bing for searches by installing Chrometana for Chrome (Download Now)
or Bing-Google for Firefox ( Download Now ),
depending on which browser you use. Chrometana also lets you search with DuckDuckGo and Yahoo.
Change SIRI Assistant Using BING
Apple has deliberately locked Siri not to use Google, but there is a workaround for those who would rather use Google than Bing.
When you want to search the web,
say “Search Google for [search term]” or “Search
DuckDuckGo for [search term]”.
Siri will launch Safari and display the results from the relevant search engine.
Change SIRI Assistant Using ALEXA
Amazon’s voice assistant is even more stubborn than Siri about using Bing rather than Google as its default search engine. However, you can perform a hack that forces Alexa to use Google instead. This comes in the form of an unofficial Alexa skill that uses Google Assistant. You can download it from https://github.com/tartanguru/alexa-assistant , but make sure you read the instructions
and are aware of the ‘known issues’ before you install this skill.
