Do screenreaders do anything sensible with <mpadded><mphantom>...</mphantom></mpadded>

See https://github.com/kisonecat/screen-reader-demo which is a MathJax extension for converting \sro{words} into

<mpadded>
  <mphantom>
    <mtext>words</mtext>
  </mphantom>
</mpadded>

and I'm curious to know what happens to this sort of thing when run through a screenreader.

The broader idea is that

\newcommand{\abs}[1]{\NAME{absolute value}\left|\CHILD{#1}\right|}
\newcommand{\innerproduct}[2]{\NAME{inner product}\langle\CHILD{#1}, \CHILD{#2}\rangle}

would permit TeX macros to simultaneously provide names and children. Presumably \NAME does nothing, and \CHILD emits its input, but on the Web these would provide another navigatable tree.

Sorry for not seeing that back at the workshop. Speech-rule-engine will simply ignore this.

But see Speech-Rule-Engine/speech-rule-engine#157 for a relevant discussion.
