Open the original- What it measures
- The authors compare the correlation of user ratings with their metric (r_RS) and with word error rate (r_RT), and test whether the two differ.
- What it does not show
- A single study. The coefficient for word error rate is a different statistic from the Spearman rho reported for ACE, so compare the two with care.
