# The prompt (--prompt) is the initial phrase that the user has to say.

# This is used to prime Whisper with how the user is expected to speak.

# Provide long context (--context) with sample moves to help Whisper decode the correct sequence.

# Longer context is better, but it slightly increases the processing time.
