Aims of this pilot study

Validate the use of virtual audience for public speaking

by assessing its capacity to elicit emotional (i.e. anxiety)

and behavorial responses (i.e. disfluencies) to confirm its

ecological validity.

Public speaking

is one of the

most feared

activities

1

and its

quality can

influence a

speaker’s

career

success

2

has

consequences

on
