众所周知，在普通话这种没有对比发音的语言中，最低音经常与喉音/音质沙哑同时出现，我们提供的证据表明，广东话的最低音也是如此。然而，喉音化对音调识别特征提取的影响，以及喉音化作为提高音调识别特征的潜力，在文献中并没有得到很好的讨论。我们从广东话和普通话的声调生成数据的语料库中提供了证据，表明喉音化是普遍存在的，并且严重干扰了60个特征的提取，并表明喉音化实际上可能是一个可以提高音调识别的特征。
It is well known that the lowest tone in Mandarin, a language without contrastive phonation, often co-occurs with laryngealization/creaky voice quality, and we provide evidence that this is also the case for the lowest tone in Cantonese. However, the effects of laryngealization on f0 feature extraction for tonal recognition, as well as the potential of laryngealization as a feature for improving tonal recognition, have not been well-discussed in the literature. We give evidence from a corpora of tonal production data for Cantonese and Mandarin that laryngealization is prevalent and significantly disturbs the extraction of f0 features, and suggest that laryngealization may in fact be a feature that could improve tonal recognition.
