根据光谱学证据，可以识别犬科动物的 12 种基本发声类型 [Canis lupus、C. latrans、C. aureus、C. exfamiliaris dingo、C. e. Hallstromi、Vulpes vulpes、Urocyon cinereoargenteus、Alopex lagopus、Chrysocyon brachyurus、Dusicyon culpaeus、Speothos venaticus、Lycaon pictus、狗]。发声可以通过连续发出两种或多种声音类型、通过这些声音的叠加或通过这两种形式的组合来混合。相同的基本声音类型在犬科动物物种之间可能在声音持续时间、连续声音之间的间隔时间、主要频率、循环性和背景方面有所不同。发育数据表明，家犬在大约 10 天龄时首先开始通过连续的声音发射来混合声音，然后在 2-3 周龄之间通过叠加来混合声音。不同背景下基本声音类型的出现频率在物种之间有所不同，但在物种内部则没有差异。讨论了驯化对犬科动物发声可能产生的影响。
On the basis of spectrographic evidence it has been possible to identify 12 basic vocal sound types of canid species [Canis lupus, C. latrans, C. aureus, C. exfamiliaris dingo, C. e. hallstromi, Vulpes vulpes, Urocyon cinereoargenteus, Alopex lagopus, Chrysocyon brachyurus, Dusicyon culpaeus, Speothos venaticus, Lycaon pictus, dogs]. Vocalizations may be mixed either by successive emission of 2 or more sound types, by superimposition of these sounds, or by a combination of these 2 forms. The same basic sound type may differ among canid species along the dimensions of sound duration, separation time between consecutive sounds, principle frequencies, cyclicity and context. Developmental data indicate that domestic dogs first begin to mix sounds by successive sound emissions at about 10 days of age and later by superimposition between 2-3 wk of age. The frequency of occurrence of the basic sound types in different contexts varied between species but not within species. The possible effects of domestication on canid vocalizations are discussed.
