निरंजन
I want to redefine few commands from package TIPA. Those are always supposed to be enclosed in \textipa{} command. The commands that I want to redefine are as follows -


\documentclass{article}
\usepackage{tipa}

\begin{document}
\textipa{\r*m}
\textipa{\v*s}
\textipa{\"*b}
\textipa{\~*a}
\textipa{\|~{i}}
\end{document}


These are the shorthand commands in package TIPA, but I couldn't find anything in tipa.sty that defines these shortcuts. How are these shortcuts defined and how to redefine them is the question that I have.
As already mentioned in my comment, these commands are defined with \DeclareTextCommand inside of t3enc.def. If you want to change them you have to first undefine the existing text command and then declare your own definition:
