E:is long and tense. It is central, half-way between open and close: the centre of the tongue is raised between close-mid and open-mid, no firm contact being made between the tongue and the upper molars. The lip position is neutral (the lip-rounding should be avoided). It coincides in quality with /q/, the difference between them being only in length. Care must be taken not to pronounce /r/ after it and to avoid any /r/-colouring of the sound.
qis short and lax. This is the most frequently occurring vowel in English, which always stands in unstressed syllables. Sometimes it is called schwa. It is half-way between open and close, it is central. The lips are neutral.
