Is there an alternative way to double quote in Latex?

LaTeX provides:

• \textquotedblleft for “,
• \textquotedblright for ”,
• \textquoteleft for ‘ and
• \textquoteright for ’.

You can define your own macro:

\newcommand\dblquote[1]{\textquotedblleft #1\textquotedblright}
\newcommand\sglquote[1]{\textquoteleft #1\textquoteright}

Or you use the csquotes package that provides nested language sensitive quote enclosing:

\enquote{Phrase\enquote{inner quote}}

For single quotes:

\enquote*{Phrase}
