Pronounciation bug in German speach with groups of letters e.g. 'rbw'

The latest version if PowerShellScript has problems with the German pronouncing groups of lower case letters, used in abbreviations or usernames e.g. 'rbw'. It worked in previous versions.

I added a small example script.

if ($Host.Version.Major -gt 2) {$Null = $Emma.Speak('PowerShell deutsch')}

#richtig , correct

$Null = $Emma.Speak('So ist es richtig')

$Null = $Emma.Speak('r')

$Null = $Emma.Speak('w')

$Null = $Emma.Speak('RW')

$Null = $Emma.Speak('WR')

# falsch, wrong

$Null = $Emma.Speak('Das ist leider falsch')

$Null = $Emma.Speak('rw')

$Null = $Emma.Speak('wr')

$Null = $Emma.Speak('rbw')

#richtig, correct, thanks to workaround

$Null = $Emma.Speak('So wird es wieder richtig')

$Null = $Emma.Speak('rw'.ToUpper())

$Null = $Emma.Speak('wr'.ToUpper())

$Null = $Emma.Speak('rbw'.ToUpper())
