Link to issue number:

fixes #17092

Summary of the issue:

When using the display speech output braille mode with no braille display connected and the braille viewer closed, zero division errors are thrown

Description of user facing changes

The user can have braille mode set to display speech output at all times, without NVDA spamming the log file

Description of development approach

Made the showSpeechInBraille function return without doing anything if the braille.handler object is not enabled

Testing strategy:

I am unable to test it, because when I run NVDA from source it crashes. @josephsl Could you confirm that this works?
