We report new spectroscopic classifications by OzDES and DEVILS of supernovae discovered by the Dark Energy Survey (ATEL #4668). The spectra (370-885nm) were obtained with the AAOmega Spectrograph (Saunders et al. 2004, SPIE, 5492, 389) and the 2dF fibre positioner at the Anglo-Australian Telescope (AAT). Object classification was performed using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), superfit (Howell and Wang, 2002, BAAS, 34, 1256) and DASH (https://github.com/daniel-muthukrishna/DASH), the details of which are reported in the table below.
