Design outcomes

Primary

Measure	Time frame
The primary outcome will be the difference in VTL between two speech sounds required for the participants to achieve a fixed level of performance. In other words, participants who can hear two speech sounds produced by two speakers with smallest VTL difference would most likely be good utilizers of this voice cue. These differences will be estimated by fitting psychometric functions to the measured scores as a function of VTL. Some of the planned experiments will provide normative data for the perception of this speech dimension in CI users, while other experiments will inform on the perceptual mechanisms involved in speech perception. The normative data for CI listeners will also be compared to that obtained in NH listeners.	—
