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

DRO, EPH, ETPH, GRO, PRO, PVOC, STARS, TPH, VPH? Help, I’m Trapped in Alphabet Soup!

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.

Determination of Headspace Volatiles in Distilled Spirits Using SPME Coupled to GC

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

DRO、EPH、ETPH、GRO、PRO、PVOC、STARS、TPH、VPH？救命啊！我被困在字母汤里啦！

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。
