("SM" | "SLM" | "NM" | "NLM") " " <lineToSay> ["<" <voiceFile> | "<!"]
<skipped> " " <lineToSay> ("<" <voiceFile> | "<!")
Say command comes in four variants: SM, SLM, NM and NLM.
Note: In script files, they are usually written as *SM.
The asterisk is ignored by the readLine function.
Each of them plays a voice file (if present) and/or shows a message
(if voice file not present or subtitles are enabled).
The difference between versions starting with "S" and "N" is that
the "N" version does not show talking animation.
The "L" versions are "blocking", i.e. they wait for the previous say command to finish.
If the line ends with "<!", it means the message continues to the next line.
Next line usually has "SM" (or other variant) repeated, but it does not have to.
Then we have the rest of the string to say (which is concatenated with the previous line)
and possibly the voice file or "<!" again.
