Dear Community, my small Tech-Startup has an browser based software for craft enterprises based in the fire alert sector. We advise our customers to use firefox on their androids. For save using our web based software, the possibility for voice sounds in background or standby mode is nesessary. We use for that No sleep JS in combination with var msg = new SpeechSynthesisUtterance(); var voices = window.speechSynthesis.getVoices();. We understood the reason stopping abuse on Youtube, sure they need to earn money. But if we dont get any workarround or help we are forced to leave the plattform firefox and create own app, this is for the users not best solution and us as small start up with 10 customers will cost much money. Thanks for helping us :)
