Speech audiometry.

Two aspects of speech audiometry, namely, the speech reception threshold and the speech discrimination scores, have been discussed in the light of their development and present day administration. Evidence was presented to forego the concept of phonetic balance in discrimination test messages for the preferable attributes of familiarity and equated list difficulty. Campbell's redistribution of the W-22 word lists was proposed as an available solution to one of these parameters. Some delineation of the single "maximal" discrimination score's relation to the prediction of the hearing impaired individual's ability to understand continuous discourse was offered. Diagnostic implications of speech audiometry were not treated.
