Primary Outcome Measures

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