It has been authored by Dr Luis Gomez-Agustina and co-authored by Dr Rusdy Hartungi. The findings of this study will, for the first time, provide practitioners guidance and reassurance on the applicability and suitability of affordable non-special loudspeakers. This in turn will enable more researchers and practitioners to undertake person-to person speech intelligibility assessments and investigations when special standardized speech sources are not available or other relevant standards allowing non-special loudspeakers as alternative speech sources are adhered to.
