Arduino Using in Project

I focus on the area of communication between the LOME and users. The main technique for this function is sound detection. I am going to use the Arduino Kit to achieve this feature. The main concept is to let the LOME detect the "bad words" that the user said inadvertently and change the petal 's color from green to red. Once the amount of red petals is more than 4, the LOME will notify the user to come to talk about the "negative" stuff.

I'm thinking about how to use the LEDs and the sound sensor to achieve this feature.

I did some searching but all of them are using the sound sensor and LEDs to turn lights off and on by clapping. So I am going to check whether there is other ways to collect voice and recognize the speech.
