Machine Learning "Audio Recognition"

Hello just seeking for help on how to run multiple tflite files in an array if that is possible I have been following the tutorial for **DIGI-KEY Machine learning for audio recognition. Which is this

I have successfully trained the Raspberri pi 4 to recognize such words like cat, left, dog, and more but I do not know how train the pi to recognize multiple words at the same time, although it can recognize a word one at a time. Here is the code that makes the code run:tflite-speech-recognition/wake_word_stop_lite.tflite at master · ShawnHymel/tflite-speech-recognition · GitHub

Thank you and have a great day.
