“语音香蕉”是语音功率分布的香蕉形情节，横坐标和纵坐标代表频率和强度。通过将语音香蕉叠加在用纯音测试的听力图上，可以预测单个语音的增减程度。语音香蕉已被构建为英语(Northern and Down，1984)和瑞典语(Liden and Fant，1954)；然而，还没有人建议将其用于声调语言，如泰语。本文介绍了泰语的语音香蕉结构，泰语是一种有21个辅音和5个声调的语言。具体来说，语音香蕉中每个音素的强度是通过功率谱密度的局部极大值与0分贝等响度等高线的声压级之差来计算的。这21个辅音的分布在170-5700赫兹和25-65分贝之间。基于7个泰国感觉神经听力的知觉测试结果，对从构建的语音香蕉和听力图中预测音素的增减进行了评估。
“Speech banana” is a banana-shaped plot of speech power distribution, where the abscissa and ordinate represent frequency and intensity. By superimposing speech banana over an audiogram, tested with pure tones, degrees of gain or loss of individual speech sound could be predicted. Speech banana has been constructed for English (Northern and Downs, 1984) and Swedish (Liden and Fant, 1954); however, none has been proposed for tonal languages, such as Thai. This work presents a construction of speech banana for Thai, a language with 21 consonants and 5 lexical tones. Specifically, intensity of each phoneme in the speech banana was calculated by differences of sound pressure level between the local maxima of power spectral density and equal loudness contour at 0 dB. Distribution of the 21 consonants is around 170-5700 Hz and 25-65 dB. Predictions of gain or loss of the phonemes from the constructed speech banana and audiograms were evaluated based on perception test results from seven Thai sensori-neural hear...
