How to increase the masterVolume past 1?

Hey, I’m trying to use p5.sound to make a web application that blasts text to speech (with p5.speech) onto my computer, I’ve tried “masterVolume(10000)”, and “myVoice.setVolume(10000)”. But they all cap at 1, is it possible for me to go past this limit?

Hello? I am still waiting for help.

Maybe you can add gain to make it louder?
