Weak

Only one voice free. Pronunciations are wonky (e.g. says daughter daw-et-her) and it spells out any word with an apostrophe in it. Lack of save feature a nuisance. Also needs multitasking support. On the plus side, its the first free text-to-speech app Ive used thatll handle large volumes of text.
