3-Minute Audio Word Replacement

I have a 3-minute recording that contains several words I now need replaced. I already know exactly which words must change and the precise timecodes where each one appears, so I will pass you a clear cue sheet along with the original audio.

Your task is to record the new words in a voice that matches the original speaker—tone, pacing, and overall timbre should be as seamless as possible—then drop them in so the edits are undetectable. Natural breathing, room tone, and background ambience must remain consistent throughout.

Deliverables
• Final, fully-mixed WAV or high-quality MP3 with the replacements integrated
• A version that keeps the edits isolated on a separate track (helpful for quick future tweaks)

Please let me know the tools or plug-ins you plan to use for voice-matching or AI cloning so I can be sure they align with my workflow. The job is straightforward and quick for someone experienced with precise dialogue editing in DAWs like Audition, Reaper, or Pro Tools, so an efficient turnaround is important.
