Develop an English language simulator program

The simulator provides the student with the opportunity to translate sentences (phrases) from Russian into English, or from English into Russian. First, a phrase appears in one language. The phrase is presented as a test and sound. Then a translation of the phrase (text and sound) appears so that the student can check himself.

For the prototype, take the phrase generator Testo nascosto. The simulator must perform all the functions of this phrase generator. We also have a number of additional functions.

1.
The phrase (first sound) is repeated a given number of times. The number of repetitions can be 1, 2, 3, infinity.
- The pause between repetitions is regulated


2.
The student is given the opportunity to change the worked words (verbs).
The English-polyglot (English-polyglot) provides 9 words. You can work with phrases from 1 to 9 words at the same time. In a phrase generator, the student cannot replace the given phrases of nine verbs. Each verb has more than 54 pairs of phrases (English phrase and its translation is Russian phrase).
In the simulator, you need to provide the ability to replace words (verbs) of 200 words (verbs). Any 9 out of 200. The 200-word phrases will be provided.

3.Remember the words (verbs) worked out

Text phrases are executed in the extension .doc. The audio files are presented in .mp3.
The choice of the next phrase-translation pair is random.

The simulator should be installed on the pages of the site Testo nascosto.
There should be protection against copying the simulator.
The trainer menu is on the Appendix.

I am waiting for offers with a price and timeline.
With respect.
