Android Enable Offline mode text to speech

It looks like not all devices are supporting Offline mode speech input. 

On my phone, i could find these settings under 

Settings -> Voice Search -> Offline Speech Recognition 

But even after having the offline speech recognition enabled, it was not working well.
