Reaction time and recognition accuracy of speech emotional intonations in short meaningless words that differed only in one phoneme with background noise and without it were studied in 49 adults of 20-79 years old. The results were compared with the same parameters of emotional intonations in intelligent speech utterances under similar conditions. Perception of emotional intonations at different linguistic levels (phonological and lexico-semantic) was found to have both common features and certain peculiarities. Recognition characteristics of emotional intonations depending on gender and age of listeners appeared to be invariant with regard to linguistic levels of speech stimuli. Phonemic composition of pseudowords was found to influence the emotional perception, especially against the background noise. The most significant stimuli acoustic characteristic responsible for the perception of speech emotional prosody in short meaningless words under the two experimental conditions, i.e. with and without background noise, was the fundamental frequency variation.
对49名年龄在20至79岁之间的成年人进行了研究，考察他们在有背景噪音和无背景噪音情况下，对仅在一个音素上存在差异的简短无意义单词中语音情感语调的反应时间和识别准确率。将结果与相似条件下智能语音话语中情感语调的相同参数进行比较。研究发现，在不同语言层面（音位和词汇语义）对情感语调的感知既有共同特征，也有某些独特之处。情感语调的识别特征似乎不随言语刺激的语言层面而变化，而是取决于听众的性别和年龄。研究发现，假词的音素组成会影响情感感知，尤其是在有背景噪音的情况下。在两种实验条件下，即有背景噪音和无背景噪音时，负责感知简短无意义单词中语音情感韵律的最重要刺激声学特征是基频变化。
