Detecting Mismatch between Text Script and Voice-over Using Utterance Verification Based on Phoneme Recognition Ranking
Table 3: Comparison between the proposed APR-based UV and the conventional LRT-based UV with the optimized thresholds.
['Test Set', 'LRT ACC', 'LRT  [ITALIC] τ', 'APR ACC', 'APR  [ITALIC] θ', 'APR Δ']
In the test sets of text scripts and voice-overs, we perform an experiment for comparing the performances of the proposed APR-based UV and the conventional LRT-based UV. APR is an alternative to the log-likelihood ratio (LLR) of the LRT-based UV. For the evaluation, we apply the optimized thresholds (i.e., τ and θ) that show the best performances for test sets to each method.
