Abstract South Africa currently lacks a pre-recorded South African English (SAE) specific speech discrimination test. In the absence of such a test, the SAE speaker recording (Tygerberg recording) of the American (USA) English (AE) CID W22 wordlists--in combination with the original American CID W22 normative data--is the most widely used alternative. The reliability and validity of this method, however, has never been formally assessed. This study assessed the performance of 15 normal hearing, female, first language SAE speakers on the first two full-lists of Tygerberg CID W22 recording at 20, 30, 40, 50, 60 and 70 dBSPL, and compared their scores to the American CID W22 wordlist normative data. Overall, the South African subjects performed worse than the original American normative data at the lower presentation intensities (< 50 dBSPL). Use of the Tygerberg CID W22 recording--with the original American CID W22 normative data--for near threshold assessment of SAE speaking subjects was therefore concluded to be problematic. Use at suprathreshold intensities (> 40 dBSPL), however, was considered a viable option. These results reiterate the need for large scale, South African specific normative studies for the CID W22 wordlists if they are to continue their role as the dominant speech discrimination wordlists in South Africa.
