Avaz India is typically on par with the international versions of Avaz Pro and Lite (barring a few months difference) in terms of features. The main difference is in the localization of the app to make it culturally relevant for the Indian user.
The main difference is the presence of the following in Avaz India:
1. Indian-accented English Voices
2. Picture vocabulary - The picture vocabulary has been localized to include Indian foods, festivals, clothes, currencies etc. See screenshot below.
3. There are additionally local language vocabularies available in 6 Indian languages - Hindi, Marathi, Tamil, Telugu, Kannada and Malayalam. These have recorded audio in the different languages.
