Description:
We need to recognize when a audio is played, letting know if it was complete or not. This is intended to dettect at what time does some advertisment was played. To avoid comparing sound, the easy way could be done in 2 steps:

1.- Having a module in which it dettects some keywords or phrases of the the audio. Like if the audio dictates using the Line In or Mic input (as any of the commercial softwares do). In this way th application "hear" and writte what it hear. In each audio they are 3 different keywords to be dettected (Begining 1, Begining 2, End). The use of them are in the next point. It needs to dettect how long is the audio, USUALLY near the 20 seconds.

2.- In the 2nd module the application is continiusly looking for the keywords of each audio. If it dettects the "Beging 1", and after it the "Begining 2" it stops looking for other audios because it assumes that it could be that audio. In this moment the application save a log in a database or file with:
Date - Time - Audio Finded - 50% (advance)

If it found the "End" audio it writes in the same Log a "100%" reference. If the limit time (long of the audio) was reached and the "End" audio doesn't appear it stop looking for it, and continue looking for the other audios.

Special Notes:
+ The audios are 90% in spanish and 10% in english.

+ The easy way to let the application know the pronunciation is to let the application "hear" the audio 1 time. We don't mind if the keywords or phrases were written correctly or not. The only purpose of them is to let be looking at them in the audio. If is clear for the application is OK.

+ The same computer could be looking for many audios, just as the voice controled application lok for many commands.

+ As a helful hint, the 2nd module never looks for the "End" audio if it didn't find first the "Begining 1 and 2". The purpose of the 2 begining audios is to let dismiss false alarms, when they appear in different order as expected. Also it didn't look for the "begiining 2" f the first was not found.
