The command "flite -f ${filename-txt}" is an instruction to run the flite text-to-speech (TTS) synthesis software, passing it a specific text file as input.

Here's a breakdown of the command:

• "flite": Refers to the executable file or command name of the flite TTS synthesis software.
• "-f": This flag is used to specify that the following argument is the file name or path of the text file to be processed.
• "${filename-txt}": This is a placeholder for the name or path of the text file you want to convert into speech. In this form, "${filename-txt}" suggests that the actual file name ends with ".txt", indicating it is a text file.

To execute the command successfully, you need to replace "${filename-txt}" with the actual name of the text file (including the file extension) you wish to convert using flite.
