Voice is a dominant component of everyday speech in all languages. The possibility is examined that its use may have evolved so that its timing in connected speech is ideal from the point of view of information theory-with voicing taking

Vocal emotions are expressed either by speech or singing. The difference is that in singing the pitch is predetermined while in speech it may vary freely. It was of interest to study whether there were voice quality differences between freely

In this study we investigated how important significant others find it to be informed, supported, and trained by speech-language pathologists (SLPs) and to what extent they perceive their expectations and needs as to these aspects to be fulfilled. Furthermore SLPs

Are the characteristic timbre and loudness of Bulgarian women's singing related to tuning of resonances of the vocal tract? We studied an Australian female singer, who practises and teaches Bulgarian singing technique. Two different vocal qualities of this style were

实验方案

There are three types of analyses: GRO, DRO, and TPH. The published methods are simply variations of these to meet the different analytical needs of the individual agencies.

In this article, SPME-GC was successfully used to identify many volatile compounds present in the headspace over several spirits.

分析方法主要分为三种:GRO,DRO和TPH。上述发表的方法只是这些方法的变种来满足各个机构的不同分析需求。
