How can I print the prosodic symbols in LaTeX?

Question

The package "metre" or "metrix" is very good to print the prosodic accent for LaTeX. But, I counldn't print several signs. Does anyone know how to print this one ?

Answer 1

I don't know a prosodic from prozac, but if you are talking about those overlines...

Note: I made them of fixed width, centered over the argument. If you want them of variable width, extending the full argument, I can make changes.

\documentclass{article}
\usepackage{amsmath,stackengine}
\newcommand\prosodic[1]{%
  \ifx1#1\expandafter\prosodicone\else
    \ifx2#1\expandafter\expandafter\expandafter\prosodictwo\else
      \ifx3#1\expandafter\expandafter\expandafter\expandafter
        \expandafter\expandafter\expandafter\prosodicthree\else
  \fi\fi\fi
}
\newcommand\prosodicone[1]{\stackengine{0pt}{#1}{$\overline{%
  \makebox[.8em]{\vphantom{#1}}}$}{O}{c}{F}{T}{L}}

\newcommand\prosodictwo[1]{\stackengine{0pt}{#1}{$\overline{\overline{%
  \makebox[.8em]{\vphantom{#1}}}}$}{O}{c}{F}{T}{L}}

\newcommand\prosodicthree[1]{\stackengine{0pt}{#1}{$\overline{\overline{%
  \overline{\makebox[.8em]{\vphantom{#1}}}}}$}{O}{c}{F}{T}{L}}

\begin{document}
dev\prosodic1{in}t 
dev\prosodic2{in}t
dev\prosodic3{in}t
mon 
ennu\prosodic3{i}!
\end{document}

One last point of style. The \overline is done relative to the argument height, so that the \prosodic1{x} accent will be lower than \prosodic1{i}. If the convention is for the height of the initial prosodic accent to be fixed, regardless of the letter, then one could simply change all three instances of \vphantom{#1} to \vphantom{X}.
