Nonparametric Bayesian Double Articulation Analyzerfor Direct Language Acquisition from Continuous Speech Signals
TABLE II: ARI for estimated latent words
['[ITALIC] σ2', '0.1', '0.5', '1.0']
The ARI for estimated latent letters shows how accurately each method estimated latent letters, which correspond to phonemes in speech signals. The ARI for estimated latent words shows how accurately each method estimated latent letters, which correspond to words in speech signals. In both tables, each column shows ARIs for different σ2. A higher ARI implies more accurate estimation of the latent variables.
