Prawf Geiriau Caerdydd--a Welsh language speech test

We have developed a set of six isophonemic word lists in Welsh, each comprising 16 vowel-consonant-vowel (VCV) words. They include the 20 commonest consonants and the 16 commonest vowel/diphthongs in Welsh, and all six lists give equivalent scores. Examination of error patterns indicates a number of differences from those found in English including a lack of voiced/voiceless confusions and an adherence to the phonotactic constraints of the Welsh language.
