R2SPIN: Re-Recording the Revised Speech Perception in Noise Test

Abstract

Speech in noise tests are an important clinical and research tool for understanding speech perception in realistic, adverse listening conditions. Though relatively simple to implement, their development is time and resource intensive. As a result, many tests still in use (and their corresponding recordings) are outdated and no longer fit for purpose. This work takes the popular Revised Speech Perception In Noise (RSPIN) Test and updates it with improved recordings and the addition of a female speaker. It outlines and evaluates a methodology which others can apply to legacy recordings of speech in noise tests to update them and ensure their ongoing usability. This paper describes the original test along with its use over the last four decades and the rationale for re-recording. The new speakers, new accent (Received Pronunciation) and recording methodology are then outlined. Subjective and objective analysis of the new recordings for normal hearing listeners are then given. The paper concludes with recommendations for using the R 2 SPIN.
