TTSLexx+

TTSLexx+ is a variant of the free TTSLexx app ( https://play.google.com/store/apps/details?id=sia.netttsengine.ttslexx ).
TTSLexx+ has a built-in dictionary for Russian language.
It allows you to improve the pronunciation of several tens of thousands of the most common words. It is certainly not comprehensive, but it can serve as a good basis for your own custom vocabulary.
The user dictionary takes precedence over the built-in one.
Pronunciation is often more a matter of habit than grammar, and if our habits don't match (or there are mistakes in the built-in dictionary), you can always fix it.
Homographs are completely excluded from the main dictionary. Due to resource consumption and possible conflicts with the user dictionary. So far, only test processing of some homographs with the ability to disable it in the application settings if the result of these experiments does not suit you.

*********IMPORTANT WARNING**********
TTSLexx+ is not recommended for use with critical applications, such as TalkBack.
The possibility of TTSLexx+ work is totally dependent on Speech Services by Google.
The built-in dictionary was created mainly on the 3.21.xxxx version of Google TTS and its usefulness, and its performance in future versions, cannot be fully guaranteed.
TTSLexx+ does not support output to an audio file.

All this you should take into account when deciding whether to purchase this application.
You have 48 hours from the date of purchase to request a refund through Google Play.
