Abstract
Novel voice enhancements for larynx amputees utilize a variety of wearable interfaces and/or artificial intelligence. However, the problem formulation remains posed as “voice restoration”, which stems from common, but limiting, assumptions about communication as being a transfer of signal from place to place (conduit metaphor). Yet beyond signal transfer, the vital part of communication is mutual influence (coordination metaphor). During conversations people coordinate their movement dynamics, i.e. adjust speech timing, intonation and gestures. By taking this perspective, informed by the newest trends in the cognitive sciences (ecological, enacted, extended cognition), we seek to shed new light on the processes of analysis of specific systems for laryngectomees. It enables us to interpret them as distributed cognitive systems, with their parts having different levels of control. The paper analyses bionic systems: laryngectomee supported with i) voice copy, ii) voice conversion, iii) silent speech iv) bionic voice or v) lean-AI interfaces. We demonstrate how using the broader perspective leads to noticing important aspects of communication and inform a more human-centered design and evaluation.
