This replaces the existing "Text-to-speech" section, placing that inside, along with a link to the newly exposed voice search settings (which will soon be expanded) and a link to the LatinIME settings (pending a link to a new section in LatinIME for just voice settings, including the comma setting and a new input language setting). The VoiceSearch and LatinIME links are smart enough to remove themselves if those don't exist on the device.
