small software reader of phrases

I need a small sotware converter text to .mp4 and .mp3 files There will be 2 fields to fill, one of them with a phrase in Spanish, another one for the same frase but in English, and there will be a optional menu with 3 options, repeat each phrase in English one time. Repeat 2 times and repeat 3 times, the phrase in Spanish always will be repeated one time. The software will be able to introduce as many phrases as the user wants, not sure if it´s better that it shows let´s say 30 fields for 15 phrases and another button to add more fields or better add one field more when the first one will be filled. .mp4 and .mp3 Files .mp3 will ears the voice off reading the text in Spanish with an accent in Spanish and phrases in English in accent American English or may be leave a option to choose between British or English accent. the voice off reading the phrases, exactly like the .mp3, not need any effect that mark the exactly word that is pronounced in the exact time, not effects needed, just the both text phrases one of them in English and one in Spanish and the voice off reading the phrases, and wait 1 second after reading the phrase in Spanish to continue reading the phrase in English after the voice read the Spanish phrase and either 1,2 or 3 times repeated in English wait 2 seconds to read the next phrase. Not need it works online, since it will be for myself. I just need it runs on my PC. Not need translate anything, just reading the text in Spanish and in English accent. Not need special voices; I think the standard voice is good, and as for me no problem if is needed internet connection to get that. I leave a cople images attached, to you see what I expected about the software and about the .mp4 file
