For various historical reasons, skill elements involved in the achievement of intelligible pronunciation have been largely neglected in both teacher training and applied research for almost 60 years. However, recently there has been a new momentum of attention to the subject of the spoken language. This chapter will outline developments in the field and then suggest efficient ways to improve students' pronunciation (and listening comprehension), paying attention to the teaching of three basic skills: the English prosodic way of conveying emphasis, how to say the peak vowels clearly, and how to guess from the spelling which vowel sound is correct.
