This application helps to study irregular verbs + some modal ones, according to the Total English Pre-intermediate course in dictation mode.
The mobile device dictates with a synthesized voice in random order with a given time interval the verbs and the number of its form. You can record your answers on paper and check with the correct answers at the end.

For speech synthesis of the Russian text to work, you need to install the official Google extension for speech synthesis and switch to it instead of PICO TTS.
