  Let $ X_{\beta}$ be a sofic $ \beta $-shift for $ \beta \in (1, 2] $. We show
that there is an $ S $-gap shift $ X(S) $ such that $ X_{\beta} $ and $ X(S) $
are right-resolving almost conjugate. Conversely, a condition on $ S \subseteq
\mathbb N\cup \{0\} $ is given such that for this $S$, there is a $ \beta $
such that $ X(S) $ and $ X_{\beta} $ have the same equivalency. We show that if
$X_\beta$ is SFT, then there is an $S$-gap shift conjugate to this $X_\beta$;
however, if $X_\beta$ is not SFT, then no $S$-gap shift is conjugate to
$X_\beta$. Also we will investigate the existence of these sort of
equivalencies for non-sofics.
