测定了英语(几种方言)、瑞典语、丹麦语、德语、法语(加拿大)、日语、广东话、普通话、俄语、威尔士语、新加坡语和越南语等12种语言的长期平均语音谱(LTASS)和一些语音的动态特征。LTASS也只针对阿拉伯语进行了测量。在15个地点，使用标准化的设备和程序，记录了10名男性和10名女性的语音样本(18个)。所有的分析都在悉尼的国家声学实验室进行。所有语言的LTASS都是相似的，尽管在统计上有许多显着的差异。这种差异很小，而且在相同语言的男性和女性样本中并不总是一致的。对于三分之一倍频程的语音，最大短期均方根水平比最大长期均方根水平高10分贝，这在不同语言和频率之间是一致的。“通用的”LTASS被认为是跨语言的，适用于许多目的，包括用于助听器处方程序和发音指数。
The long-term average speech spectrum (LTASS) and some dynamic characteristics of speech were determined for 12 languages: English (several dialects), Swedish, Danish, German, French (Canadian), Japanese, Cantonese, Mandarin, Russian, Welsh, Singhalese, and Vietnamese. The LTASS only was also measured for Arabic. Speech samples (18) were recorded, using standardized equipment and procedures, in 15 localities for (usually) ten male and ten female talkers. All analyses were conducted at the National Acoustic Laboratories, Sydney. The LTASS was similar for all languages although there were many statistically significant differences. Such differences were small and not always consistent for male and female samples of the same language. For one-third octave bands of speech, the maximum short-term rms level was 10 dB above the maximum long-term rms level, consistent across languages and frequency. A ''universal'' LTASS is suggested as being applicable, across languages, for many purposes including use in hearing aid prescription procedures and in the Articulation Index.
