The music and spoken language domains share acoustic properties such as fundamental frequency (f0, perceived as pitch), duration, resonance frequencies, and intensity. In speech, the acoustic properties form an essential part in differentiating between consonants, vowels, and lexical tones. This study investigated whether there is any advantage of musicality in the perception and production of Thai speech sounds. Two groups of English-speaking adults-one comprising formally trained musicians and the other non-musicians-were tested for their perception and production of Thai consonants, vowels, and tones. For both groups, the perception and production accuracy scores were higher for vowels than consonants and tones, and in production, there was also better accuracy for tones than consonants. Between the groups, musicians (defined as having more than five years of formal musical training) outperformed non-musicians (defined as having less than two years of formal musical training) in both the perception and production of all three sound types. Additional experiential factors that positively influenced the accuracy rates were the current hours of practice per week and those with some indication of an augmentation due to musical aptitude, but only in perception. These results suggest that music training, defined as formal training for more than five years, and musical training, expressed in hours of weekly practice, facilitate the perception and production of non-native speech sounds.
音乐和口语领域具有一些共同的声学特性，如基频（f0，即感知到的音高）、时长、共振频率和强度。在语音中，这些声学特性是区分辅音、元音和声调的重要组成部分。本研究调查了音乐才能在泰语语音的感知和发音方面是否具有优势。两组说英语的成年人——一组是受过正规音乐训练的音乐家，另一组是非音乐家——接受了泰语辅音、元音和声调的感知与发音测试。对于两组而言，元音的感知和发音准确率得分高于辅音和声调，并且在发音方面，声调的准确率也高于辅音。在两组之间，音乐家（定义为接受过五年以上正规音乐训练）在所有三种音类的感知和发音方面均优于非音乐家（定义为接受过不到两年正规音乐训练）。对准确率有积极影响的其他经验因素包括每周当前的练习时长以及那些因音乐天赋而有一定提升迹象的因素，但仅在感知方面如此。这些结果表明，定义为五年以上正规训练的音乐训练以及以每周练习时长表示的音乐训练，有助于非母语语音的感知和发音。
