Therefore, for an Arduino implementation, this process translates to connecting a measuring device (microphone for sound) to the MCU and sampling the value at the device by the ADC at a constant rate. The Arduino ADC senses voltage levels (typically in the range of 0-5V) and converts them to values in the range of 0 to 1024 (10 bit).

then something to analyze the audio and the realtime sensing. That is the difficult / impossible thing to do unfortunately, two sounds can sound the same to us but produce vastly different waveforms. The best option you could try is an Arduino voice recognition shield and see if you can train it to your sounds.
