“…Whether speech input creates risks or barriers for users depend on the users, context, and device [94]. Examples include the user encountering execution errors and the input device may experience recognition errors [95]. In addition, the user's utterance ability and familiarity with the input device may influence the effectiveness of speech recognition [66,96].…”

On the basis of innovation resistance theory (IRT) and technology acceptance model (TAM), this study explores the preference of college students for keyboard typing over speech input for document processing. Results showed that functional barriers (i.e., usage, value, and risk barriers) and psychological barriers (i.e., tradition and image barriers) positively affect users' resistance to change. Perceived ease of use and perceived usefulness influence the intention to adopt speech input, which is consistent with TAM. Resistance to change was proven to negatively affect users' intention to adopt speech input. Academically, results confirm that although barriers to speech input currently exist, users still consider speech input as easy and useful and plan to adopt the technology. In practice, speech recognition system companies can significantly enhance users' adoption intentions by reducing barriers and increasing their perception of ease of use and usefulness of speech input.

Interacting with an embodied interface

Despite their potential for facilitating interaction between a user and computer, an embodied agent and voice command have not been examined enough for their matching effects. The current study proposes that an embodied agent and voice command generate positive evaluative outcomes, particularly when they are accompanied by each other. To test this prediction, we conducted a 2 (visual output: embodied agent vs. geometric figure) × 2 (input modality: voice command vs. remote controller) between-subjects experiment (N = 52), and examined whether visual output and input modality jointly influence participants’ social attribution (i.e., anthropomorphism, animacy, likability, and perceived intelligence), social presence, and satisfaction. Results show that voice command does facilitate users’ social attribution and social presence, but only when an embodied agent was presented. Also, the effects of voice command on social presence and satisfaction were mediated by anthropomorphism and perceived intelligence respectively, but only when the interface displayed an embodied agent. The present study evidences the holistic nature of human-computer interaction, revealing the importance of matches in the input and output interface.
