I'm developing an application using the Web Speech API for speech synthesis. According to the API specification SpeechSynthesis.getVoices() should retrieve the voices available on the system. On my iPad Pro, 12,9 inch, 3rd generation, iOS 16 however this doesn't return all voices installed on the system. In system settings (Accessibility -> Spoken content -> Voices -> German) e.g. I see these voices: Anna Eloquence Markus Petra Siri Viktor Yannick However if for SpeechSynthesis.getVoices() I only get the voices within the group "Eloquence": Eddy Flo Grandma Grandpa Reed Rocko Sandy Shelley All other voices (Anna, Markus, etc.) are missing. Is this a bug or is it intended by Apple that it's impossible to use all voices? This is independent of the browser, it's the same for Safari, Chrome or Firefox. Use this in order to test which voices are available using the WebSpeech API: https://plnkr.co/edit/E2etsrUZVOVfrDwG
