The purpose of this investigation was to rank 250 Korean monosyllables by their degree of difficulty and to find out talker effects. In the process of developing word lists in word recognition tests, important factors were equal degree of difficulty between word lists
and equal range of difficulty within the individual lists. 250 monosyllables recorded by male and female talkers were presented to 2 subjects at intensity level ranging from -5 to 40 dBHL. These words were ranked by the order of difficulty for two talkers. The word ‘mal’(말) was shown as the most easy word for both talkers. ‘bok’(복), ‘bbul’(뿔), ‘set’(셋) were shown as hardest words for both talkers. The methods and results used in this investigation should help establish full lists with 50 words and half lists with 25 words.
This procedure can shorten the test time and decrease patients’ fatigue. In addition to issues on degree of difficulty, some studies provided evidences of talker variables in the same materials. The effect of talker variables, such as gender difference and a person’s characteristics of speaking, can be controlled with some limitations when words are recorded in a digital format. These systematic approaches may lead to helpful information on rehabilitation of the hearing impaired.
