Voice coding experiences for developers with physical impairments

Abstract

PurposeThis research explores the current working practices of voice coders with physical impairments and investigates their perceptions of a research prototype utilising a fixed grammar speech coding approach.Design/methodology/approachSemi-structured interviews were initially conducted with seven voice coders with physical impairments to understand their development practices, followed by an exploratory user study with five disabled voice coders to obtain their feedback on a fixed grammar voice coding system.FindingsInterviews provided new insights around the tools voice coders utilise, the need for multimodal coding approaches, as well as experiences in working within mixed ability development teams. Findings from the user evaluation elicited views around the need for distinct monosyllable voice commands, as well as other requirements to support efficient voice coding (e.g. command chaining, intuitive navigation, and custom command definition).Research limitations/implicationsThe research was conducted with experienced voice coders which may have influenced perceptions of the voice coding prototype. The system was also evaluated over a single evaluation session, whereas longitudinal research with novice voice coders could also present additional insights.Practical implicationsFurther research is required into customisable multimodal voice coding approaches for developers with physical impairments who may have varying levels of experience in coding via alternative methods.Originality/valueThe findings present new insights around the working practices and unique requirements of voice coders with physical impairments and highlights important new avenues for future research.
