Will voice understand my cookbook's name, like "B Book"?

Voice understands cookbook and recipe names even when speech-to-text spells them oddly. Names made of single letters work too — a cookbook called "B Book" opens whether Voice hears "B book", "be book" or "bee book" (and the same for "C" heard as "see" or "sea", and so on). For best results say "open my [name] cookbook" — for example "open my B Book cookbook" or "open my Sunday Roasts cookbook". If two names sound alike, Voice shows you the closest matches to tap.
