You can now talk to your Android TV in Hindi and Vietnamese. The update comes only to TVs running on Android TV and not TVs from third parties that support the Google Assistant. So if you have an LG TV running on WebOS with support for the Google Assistant or a Samsung TV running on Tizen with support for the Assistant, then you will not be able to talk to the assistant in Hindi on those TVs. Google’s support page reads, “On Android TVs, the Google Assistant is available in English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese (Brazilian), Spanish, and Vietnamese. More languages are coming soon. On TVs that don't run the Android TV operating system, available languages vary. On LG TVs, the Google Assistant is available in English, French, German, Italian, Japanese, Korean, Portuguese (Brazil), and Spanish. On all other TVs, the Google Assistant is only available in English.” If you don't have access to Hindi on your Android TV, then worry not as the manufacturer of the TV may be pushing out the update in phases.
The Google Assistant on Smart TVs has evolved considerably since its inception. If you have smart home appliances that work with the Google Assistant, then you can control them from the comfort of the TV. A TV like the Sony A9G (read our review here) can be switched on and off from standby mode by simply using your voice, giving you a more hands-free experience with the TV. A TV like the LG C9 (read our review here) that runs on WebOS supports both the Google Assistant and Alexa along with compatible IoT devices.
When going to purchase a smart TV, you should know that not all TVs running on Android are running on the Android TV platform. Most budget TVs run on AOSP (Android Open Source Platform). AOSP essentially gives users a mobile Android experience including apps and streaming services and most of the time is a cumbersome experience. Companies like Panasonic, Philips and more have TVs running on their own OS.
