I wondered into examining the use and design of voice interfaces a few years ago during my PhD (see this paper or the summary blog post). The rapid mass marketisation of the technology has led to the quick succession of research paper after research paper and Medium post after Medium post, but there is seemingly no “golden” set of specific usability heuristics for voice interfaces. Rather, there are several re-examinations of similar rules that were crafted for GUIs, so far (but the times, they are a changin’). Voice interfaces are different for a plethora of well-rehearsed reasons but much of this is to do the invisibility and ephemerality of speech.
