For instance, while the Brazilian striker Ronaldo is rendered as 朗拿 度 long5-naa4-dou6 in Cantonese, other phonetically similar candidates like 朗娜度 long5-naa4-dou6 or 郎拿刀 long4-naa4-dou1 1 are least likely.
hence naming is more of an art than a science, and automatic transliteration should avoid over-reliance on the training data and thus missing unlikely but good candidates.
