Get Tamil Text to Speech old version APK for Android
Tamil Text to Speech is text to audio program
Tamil Text to Speech is text to audio program which allow you to convert Tamil text to audio, you might need a Tamil keybpard beause the text to speech engine only translate Tamil letters
I recommend downloading Tamil keyboard from playstore
and there are some limitation, because it is a free version so you can only use 500 letters at a time
