Can i make a background service that always runs a speech recognition

Question

i want to make an application that i can run it over voice like siri or google assistant, so in order to make it i have to implement the code in a background or foreground service which will run speech recognizer so is this possible,because of the limitation of the working services on android Oreo and higher this make me stuck in the middle of nowhere and i'm not so professional so i could figure this out myself

i have tried to make a foreground service with IntentService so that it could make the work on the background without freezing the UI and the Speech recognizer didn't work
