Interrupt Sound as voice is being recognized (Google Speech)

I need to create a IVR that is able to detect buzzwords, that is to say the user will be prompted with a list of voice options but if the user says one of them even when they have not been fully played the IVR sould redirect to another option.
Is it possible to use speech recognition as sound is being played with asterisk?
Now i’m trying EAGI with Google Speech Cloud but it blocks even MusicOnHold. Does anybody know a way to do this?
