Highlights
• Domestic dogs can recall to an artificial agent and respond correctly to its pre-recorded, owner spoken verbal cues as reliably as to their owners in person and while alone in the test room.
• Generalisation of previously learned behaviours to the novel agent in all conditions was rapidly achieved.
• No behavioural indicators of poor welfare were recorded during interaction with the agent directly.

Abstract: Human-canine communication technology for the home-alone domestic dog is in its infancy. Many criteria need to be fulfilled in order for successful communication to be achieved remotely via artificial agents. Notably, the dogs’ capacity for correct behavioural responses to unimodal verbal cues is of primary consideration. Previous studies of verbal cues given to dogs alone in the test room have revealed a deterioration in correct behavioural responses in the absence of a source of attentional focus and reward. The present study demonstrates the ability of domestic pet dogs to respond correctly to an artificial agent. Positioned at average human eye level to replicate typical human-dog interaction, the agent issues a recall sound followed by two pre-recorded, owner spoken verbal cues known to each dog, and dispenses food rewards for correct behavioural responses. The agent was used to elicit behavioural responses in three test conditions; owner and experimenter present; experimenter present; and dog alone in the test room. During the fourth (baseline) condition, the same cues were given in person by the owner of each dog. The experiments comprised a familiarisation phase followed by a test phase of the four conditions, using a counterbalanced design. Data recorded included latency to correct response, number of errors before correct response given and behavioural welfare indicators during agent interaction. In all four conditions, at least 16/20 dogs performed the correct recall, cue 1 response, and cue 2 response sequence; there were no significant differences in the number of dogs who responded correctly to the sequence between the four conditions (p = 0.972). The order of test conditions had no effect on the dogs’ performances (p = 0.675). Significantly shorter response times were observed when cues were given in person than from the agent (p = 0.001). Behavioural indicators of poor welfare recorded were in response to owners leaving the test room, rather than as a direct result of agent interaction. Dogs left alone in the test room approached and responded correctly to verbal cues issued from an artificial agent, where rapid generalisation of learned behaviours and adjustment to the condition was achieved.
