Earl W. Stevick, Adapting and Writing Language Lessons… (1971)
“ For one not used to a second language, and particularly a tone language, accurate pronunciation is difficult to achieve; but it is also crucially important. The drills that may seem monotonous at first are actually a golden opportunity to learn to control pronunciation at the outset, so that habits of sloppy pronunciation will never have a good chance to develop. At the same time, every utterance in every drill is a perfectly good and natural utterance that will be found useful in daily life. The details of Igbo pronunciation will be outlined step by step in the early lessons. ”
