IPA Consonant Chart Empty Cells Explained
The International Phonetic Alphabet (IPA) consonant chart uses specific conventions for empty cells to represent information about sound production possibilities.
Shaded Empty Cells Meaning
Shaded empty cells within the IPA consonant chart signify sound combinations that are not possible to produce using the known human vocal tract. These represent physiological impossibilities.
Therefore, statement 1 is correct.
Non-shaded Empty Cells Meaning
Conversely, non-shaded empty cells indicate sound configurations that are theoretically possible to articulate but have not been documented or observed in any known human language. These are potential sounds awaiting discovery.
Therefore, statement 4 is correct.
Based on the conventions of the IPA consonant chart, the true statements are:
- The shaded empty cells indicate sound configurations that are physiologically impossible to produce. (Statement 1)
- The non-shaded empty cells indicate sound configurations that are physiologically possible to produce but have not yet been discovered in the world’s languages. (Statement 4)
