有必要改进对声音行为的原因和后果的评估。缺乏对呼唤或歌曲产生的背景的描述是因为其定义的复杂性。环境是由许多物理和社会参数组成的，因此它的分析应该是多维的。经典方法涉及相对主观的数据简化。这是由于预先选择了可能涉及的参数，因为当因素数量增加时，分析会迅速变得复杂。本文描述了一种有用的方法，它允许更广泛的潜在参数的探索和可视化显示。为后续分析选择的参数是由显示显示为最相关的，因此不是任意的。我们将这种方法应用于观察呼叫产生之前和之后的事件（外部或内部的群体）或行为（包括姿势）。Campbell's monkeys Cercopithecus campbelli的叫声由几种刻板的亚型组成，这就提出了这种变化对动物是否具有功能意义的问题。我们提出了三个应用该方法的例子，以详细描述给定调用类型的生产上下文，检测生产的特定时间序列，并区分结构上接近的子类型。
There is a need to improve the assessment of causes and consequences of vocal behaviour. The lack of descriptions of the context of call or song production comes from the complexity of its definition. The context is composed of numerous physical and social parameters and therefore its analysis should be multi-dimensional. Classical approaches involve a relatively subjective data reduction. This is due to a pre-selection of the parameters which may be potentially involved, as the analysis becomes rapidly complicated when the number of factors increases. This paper describes a helpful method that allows a much wider range of potential parameters to be explored and displayed visually. The parameters selected for subsequent analysis are those indicated by the display as most relevant and are therefore not arbitrary. We applied this method to observations of events (external or internal to the group) or behaviours (including postures) preceding and following call production. Calls of Campbell's monkeys Cercopithecus campbelli present call types composed of several stereotyped sub-types, raising the question of whether or not such variations have a functional meaning for animals. We present three examples of the application of this method to describe in detail the context of production of a given call type, to detect specific temporal sequences of production and to discriminate between structurally close sub-types.
