We present the first results of a spectroscopic survey of southern and equatorial Algol-type eclipsing binary systems with mass-accreting pulsating components (oEA stars) using the 2.4-m Thai National Telescope (TNT) and the 10-m South African Large Telescope (SALT). The survey aims to find orbital and binary parameters and to detect the high-degree non-radial pulsations (NRPs). We report the detection of high-degree NRPs in AS Eri, WYCet, VYHya, GQTrA, BDVir, and UWVir.
