Translators: Orca uses Speech Dispatcher to present content to users via text-to-speech. Speech Dispatcher has a feature to control how capital letters are presented: Do nothing at all; say the word 'capital' prior to presenting a capital letter (which Speech Dispatcher refers to as 'spell'), or play a tone (which Speech Dispatcher refers to as a sound 'icon'). Orca refers to these things as 'capitalization style'. This string is the text of the label through which users can choose which of style they would prefer.
