Google rolled out an update to its Voice Search on August 14, which allows users to use Tamil, Sinhala and 28 other more languages in its Voice Search. We, as native speakers of Sinhala and Tamil, can use these languages to give word queries to google voice and other google apps as well.
You can start using Sinhala/Tamil as the voice-search language by following this simple steps,
Step 1:- Open Google Settings on your android mobile
Step 2:- Select Search and then hit Language
Step 3:-Select your preferred language from the list.
Once you have done the part above, you can just tab on the microphone symbol on your Gboard and start speaking. Google is also rolling out Voice search support for Srilanka languages on its iOS app.
The new languages are available in Cloud Speach API and it will probably arrive across other Google apps and products, including the Translate app in the next couple of weeks.
