@soumendra thanks for your feedback. Before moving into any direction, it would be good to understand how long would it take to read a sentence today and also how long (on average) would it take to read a 30 characters sentence.
I don’t know if you are, but If you can get a Odia linguistic expert, it would be useful for defining the exact number we would need. We want sentences that require less than 8 seconds to read (for user experience).
Thanks.
