Voice recognition of Different Devices

So hello there everyone, I just came up with an idea and I want to know if this is possible or has anyone done similiar to something like this before?

The main goal of the project: For the arduino to recognize two different types of voices(non-human). ( I am not quite sure how they differ, but I guess each voice is different in Hz.) To explain even better:

If buzzer 1 gives off sound LED 1 should blink as soon as the voice come from buzzer 1.

If buzzer 2 gives off sound LED 2 should blink until the voice stops coming from buzzer 2. etc.

The buzzer is just an example as I have said in my example.

I have looked up arduino sound modules for this , but all I could see are practical uses of a human voice where they order the motor to turn or something like that.

Soo I'm pretty sure I need to study sounds first. How they differ from each other etc. I want to look up similiar applications but I couldn't find any.

So what should I look up to in this case? Some guidance would be nice to work with here.

Thanks in advance,

You won't find much using an Arduino. Yes, you first goal it find the specific differences in the sounds and how to quantify those differences. Then look for sensors that can detect those sounds. Once you have that, then you can write a program to differentiate one sound from the other.

I suspect you will need start with microphone, amplifier and an oscilloscope to be able to SEE the differences in the sounds.
