AI Audiobook Adaptation of Screenplay

I’m ready to turn my screenplay into a captivating audiobook powered by AI narration. The story opens with high-stakes drama, then shifts into a humorous spirit that calls for an enthusiastic lift in energy. To make that tonal journey believable, I’ll need four to six distinct character voices—each one clearly differentiated yet cohesive within the overall soundscape.

Here’s what I’d like from you:
• Demo reel: short voice samples for every primary character so I can lock in tone, pacing, and any needed accents before full production.
• Full-length audiobook: professionally edited, chapter-separated WAV or high-bitrate MP3 files with clean pacing, noise-free mastering, and consistent volume.
• Seamless tone transition: narration should begin dramatic and gradually shift to an upbeat, comedic enthusiasm once the humor element arrives.
• Limited revisions: at least one round for voice tweaks and one for final polish after I review the complete draft.
• Source and licensing: delivery of project files or confirmed usage rights for any AI voice service you employ (e.g., ElevenLabs, Amazon Polly, Google Cloud TTS).

If you have experience blending multiple AI voices, directing tone shifts, and finalizing audio for commercial release, I’d love to hear your approach and a brief timeline.
