Arranging a group of professional actors to table read scripts for a writer is extremely beneficial, but also costly. Recent advancements in natural-sounding synthesized voice, text-to-speech, and transcription technology (like OpenAI’s Whisper?) can be leveraged to offer this functionality at the click of a button.
Key functionality: ability to assign a narrator for action lines and different voices to different characters to play through the script.
Potential problem: I am unsure whether this would have to be processed on a cloud service and what the privacy implications would be for a writers material.
