CNN曾將「先天音感」(Tonal talent)譽為香港十大無敵優點之首，原來早有研究發現，用廣東話嘅小朋友音感比普通話嘅更強：「Cantonese-speaking children had more advanced tone awareness than Mandarin-speaking children. This was likely because Cantonese has a more complicated tone system than Mandarin.」

研究人員做咗兩次試驗，用普通話、與廣東話共通字、假字（Pseudo words）辨音做測試。佢地發現，廣東話小朋友無論喺辨認聲調(Tone)、頭子音(Onset)、韻攝(Rime)，能力都凌駕普通話小朋友。

研究人員將結論歸究兩個原因：廣東話小朋友有雙語環境( bilingualism)以及廣東話有更複雜嘅語音系統。
