  We produce affine interval exchange transformations (AIETs) which are
topologically conjugated to (standard) interval exchange maps (IETs) via a
singular conjugacy, i.e. a diffeomorphism $h$ of $[0,1]$ which is $C^0$ but not
$C^1$ and such that the pull-back of the Lebesgue measure is a singular
invariant measure for the AIET. In particular, we show that for almost every
IET $T_0$ of at least two intervals and any vector $w$ belonging to the
central-stable space $E_{cs}(T_0)$ for the Rauzy-Veech renormalization, any
AIET T with log-slopes given by $w$ and semi-conjugated to $T_0$ is
topologically conjugated to $T$. If in addition, if $w$ does not belong to
$E_s(T_0)$, the conjugacy between $T$ and $T_0$ is singular.
