Segments Without Letters
The remaining blank cells on the IPA chart can be filled without too much difficulty if the need arises. Some ad hoc letters have appeared in the literature for the retroflex lateral flap, the voiceless lateral fricatives, the epiglottal trill, and the labiodental plosives. (See the grey letters in the PDF chart.) Diacritics can supply much of the remainder, which would indeed be appropriate if the sounds were allophones. If a sound cannot be transcribed, an asterisk ⟨*⟩ may be used, either as a letter or as a diacritic (as in ⟨k*⟩ sometimes seen for the Korean 'fortis' velar).

Famous quotes containing the words segments and/or letters:
“It is not, truly speaking, the labour that is divided; but the men: divided into mere segments of men—broken into small fragments and crumbs of life, so that all the little piece of intelligence that is left in a man is not enough to make a pin, or a nail, but exhausts itself in making the point of a pin or the head of a nail.”
—John Ruskin (1819–1900)
“Harvey: About this Voltaire.
Helene: What about him?
Harvey: How’d he ever get time to do all he did?
Helene: He lived to be old.
Harvey: Even so, how many letters did he write?
Helene: Oh, I don’t know exactly. Thousands.
Harvey: I can’t remember when I even wrote one.
Helene: You should try.
Harvey: It’s too late. I wouldn’t know where to send it.”
—Tom Waldman (d. 1985)
