In Firefox, speech synthesis voices do not start loading until after the first call to window.speechSynthesis.getVoices(). A way to mitigate this issue is to call the method at the beginning of page load, then wait a few seconds before calling the method again. Voices will remain loaded until all tabs that have called this method have been closed.
