  In 1979 Pisier proved remarkably that a sequence of independent and
identically distributed standard Gaussian random variables determines, via
random Fourier series, a homogeneous Banach algebra $\mathscr{P}$ strictly
contained in $C(\mathbb{T})$, the class of continuous functions on the unit
circle $\mathbb{T}$ and strictly containing the classical Wiener algebra
$\mathbb{A}(\mathbb{T})$, that is, $\mathbb{A}(\mathbb{T}) \subsetneqq
\mathscr{P} \subsetneqq C(\mathbb{T}).$ This improved some previous results
obtained by Zafran in solving a long-standing problem raised by Katznelson. In
this paper we extend Pisier's result by showing that any probability measure on
the unit circle defines a homogeneous Banach algebra contained in
$C(\mathbb{T})$. Thus Pisier algebra is not an isolated object but rather an
element in a large class of Pisier-type algebras. We consider the case of
spectral measures of stationary sequences of Gaussian random variables and
obtain a sufficient condition for the boundedness of the random Fourier series
$\sum_{n\in \mathbb{Z}}\hat f(n) \,\xi_n \exp(2\pi i n t)$ in the general
setting of dependent random variables $(\xi_n)$.
