The present study investigated changes in the prosodic and acoustic-phonetic features of isolated words by four male talkers speaking in quite and in pink noise at a level of 95 dB SPL. Speech samples were collected both with and without an oxygen mask. Changes in duration, fundamental frequency, total energy, and formant center frequency were analyzed. In addition to the expected changes of increased pitch and amplitude associated with speaking in noise without an oxygen mask, significant effects were found (particularly in the formant center frequencies) as a result of using the oxygen mask. When the oxygen mask was employed, no further significant changes were caused by adding noise to the speaking situation.
本研究调查了四名男性说话者在安静环境以及95 dB SPL的粉红噪声环境下说出的孤立单词的韵律和声学语音特征的变化。语音样本在佩戴和不佩戴氧气面罩的情况下均被采集。对时长、基频、总能量和共振峰中心频率的变化进行了分析。除了在不佩戴氧气面罩的噪声环境中说话时预期的音高和幅度增加的变化外，还发现了使用氧气面罩所产生的显著影响（特别是在共振峰中心频率方面）。当使用氧气面罩时，在说话环境中添加噪声不会导致进一步的显著变化。
