The capacity of nonhuman primates to actively modify the acoustic structure of existing sounds or vocalizations in their repertoire appears limited. Several studies have reported population or community differences in the acoustical structure of nonhuman primate long distance calls and have suggested vocal learning as a mechanism for explaining such variation. In addition, recent studies on great apes have indicated that there are repertoire differences between populations. Some populations… 

Two organizing principles of vocal production: Implications for nonhuman and human primates

Evidence of acoustic modification of calling associated with background noise, conditioning effects, audience composition, and vocal convergence and divergence in nonhuman primates is reviewed and it is suggested that most are more consistent with affectively grounded mechanisms.

The function and mechanism of vocal accommodation in humans and other primates

It is found that at the mechanistic level, many cases of accommodation can be explained with an automatic perception–production link, but some instances arguably require higher levels of vocal control.

Orangutan (Pongo spp.) whistling and implications for the emergence of an open-ended call repertoire: a replication and extension.

Viceless call learning in orangutans implies that some important components of human speech learning and control were in place before the homininae-ponginae evolutionary split.

Chimpanzee pant-hoots encode information about individual but not group differences

The limited evidences for vocal learning in Pan suggest that extensive vocal learning emerged in the human lineage after the divergence from Pan, and this analysis of pant-hoots from chimpanzees in the neighboring Kasekela and Mitumba communities at Gombe National Park, Tanzania, and the geographically distant Kanyawara community at Kibale National park, Uganda.

Vocal fold control beyond the species-specific repertoire in an orang-utan

Results indicate a latent capacity for vocal fold exercise in a great ape in real-time, up and down the frequency spectrum, across a register range beyond the species-repertoire and in a co-operative turn-taking social setup.

University of Birmingham Functional flexibility in wild bonobo vocal behaviour

A shared principle in the evolution of language and the development of speech is the emergence of functional flexibility, the capacity of vocal signals to express a range of emotional states

Functional flexibility in wild bonobo vocal behaviour

Evidence that wild bonobos use a specific call type across a range of contexts that cover the full valence range in much of their daily activities is found, interpreting this evidence as an example of an evolutionary early transition away from fixed vocal signalling towards functional flexibility.

Whistling shares a common tongue with speech: bioacoustics from real-time MRI of the human vocal tract

Real-time magnetic resonance imaging is used to examine the muscular control of whistling to describe a strong association between the shape of the tongue and the whistled frequency, which is consistent with the role of whistled languages as proxies for spoken languages, in which one of the acoustical features of speech sounds is substituted with a frequency-modulated whistle.

Imitating Sounds: A Cognitive Approach to Understanding Vocal Imitation

It is suggested that sound imitation capacities may have evolved in certain mammals to enhance both the perception of ongoing actions and the prediction of future events, rather than to facilitate mate attraction or the formation of social bonds.

Does learning affect the structure of vocalizations in chimpanzees?

Within-group variation in call structure of the captive groups was similar to that found in a group of wild Ugandan chimpanzees, suggesting the presence of species-specific constraints on this call within which different populations can converge on local variants.

It is discussed how anatomy and physiology may provide constraints resulting in “honest” acoustic indicators of body size, and the nature of the vocal tract's contribution to call production is discussed.

The different roles of social learning in vocal communication

It is found that unexpected genetic or environmental factors can have considerable effects on vocal behaviour in birds and mammals and are often more likely to cause changes or differences in vocalizations than investigators may assume.

It is discussed that differences in loud calls are probably most parsimoniously explained by gene flow (or the lack thereof) between the populations and that future studies of genetic differences are crucial to test this hypothesis.
