That Sound Human
A methodology and production toolkit for creating multilingual podcasts with synthetic voices — developed by one person using AI-augmented workflows.
Three Voices, One Conversation
AI gets 80% right. The methodology is the other 20% — dialogue dynamics, emotional arcs, and the discipline of knowing when not to let the AI talk.
Guides the listener. Asks questions a curious non-expert would ask. Controls pacing and transitions.
Delivers the substance. Explains, contextualizes, builds narrative. The voice listeners trust.
The historical or primary voice. Quotes, letters, original words. Adds authenticity and emotional punch.
Emotional Arc Design
Every episode follows a deliberate emotional trajectory — not flat information delivery. Scripts are structured around tension, discovery, and resolution, using audio tags to control vocal delivery at the phrase level.
Five Stages, End to End
Each stage uses AI differently. The skill is knowing which tool for which job — and where human judgment is non-negotiable.
Research
ClaudeDeep topic research, source analysis, fact compilation. AI reads hundreds of sources and extracts what matters.
Script
Claude + HumanThree-voice dialogue writing with emotional arcs, segment pacing, and audio tag markup. The creative core.
Generate
ElevenLabs / ChatterboxText-to-dialogue generation with full context awareness. Character voices maintain personality across episodes.
Post-process
Python + FFmpegAutomated silence trimming, segment stitching, per-line repair. Custom tools for precision editing.
Master
FFmpegLoudness normalization to podcast standards (-16 LUFS), music mixing, final export.
30+ Synthetic Voices, Zero Clones
Every voice is designed from scratch — age, accent, personality, speech patterns. The same character sounds like the same person across languages. Voice design is a discipline, not a button click.
