AB  - The speech transmission index (STI) is one of the most widely used standardized methods for objective prediction of speech intelligibility. This research verifies the current STI for the English language for male speech under reverberant conditions using two binaural listening methods: real-life and headphones. For most scenarios, the intelligibility of phonetically balanced word lists was lower for both headphones and real-life than indicated by the standard PB/STI curve included in IEC 60268-16. Headphone listening had a statistically significant lower intelligibility than real-life listening. The results suggest that under reverberant conditions, the speech intelligibility for a specific STI value is more degraded than suggested by the standard PB/STI curve for STI values lower than 0.60.
