say:tldr:1c13f

The given command is using the "say" command, which is typically used on macOS systems to convert text to speech. Here's a breakdown of the components:

• "say": The command itself initiates the text-to-speech synthesis.
• "--voice=${voice}": This option denotes the voice to be used in the speech synthesis. The value of "${voice}" is a placeholder that should be replaced with the desired voice name.
• "--rate=${words_per_minute}": This option sets the rate or speed at which the text will be spoken. The value of "${words_per_minute}" is another placeholder that should be substituted with the desired number of words per minute.
• "${I'm sorry Dave, I can't let you do that-}": This is the input text enclosed in quotes. The text inside the quotes will be converted to speech. In this case, the sentence "I'm sorry Dave, I can't let you do that" will be spoken aloud.

Overall, this command will use the specified voice and rate values to convert the input text to spoken words using the "say" command on a macOS system.
