# Category 10 — Style Transfer and Voice

This category covers the research, tooling, and practitioner knowledge behind making AI output sound like a specific person rather than a generic language model. That includes formal text style transfer (attribute-to-attribute, non-parallel, supervised), authorship conditioning (voice profiles, author embeddings, idiolect capture), register and tone control, detection and removal of LLM-isms, and stylometric measurement. Adjacent topics handled elsewhere: pure detector-evasion (Category 05), persona/character design (Category 03), long-term personalization memory (Category 20), chain-of-thought rendering (Category 06).

## Angle files

- [A-academic.md](A-academic.md) — 37 papers spanning the full arc from 2012 to April 2026: the Jin/Mir survey and evaluation framework, the disentanglement era (Hu, Shen, Li, Lample), decoding-time steering (PPLM, GeDi, FUDGE, DExperts), paraphrase-pivot (STRAP), authorship and stylometry (STAR, CAV, BertAA, PAN, SIGKDD 2025 survey), LLM-era methods (Reif 2022, TinyStyler EMNLP 2024, STEER, Patel 2024, Neurobiber 2025), and 2025–2026 findings (EMNLP 2025 "Catch Me If You Can," Jemama 2025 perplexity-vs-style split, ZeroStylus long-text transfer, Profile-to-PEFT hypernetwork, GRAVITY DPO, interpretable stylistic variation 2026, "How LLMs Distort Our Written Language" 2026).
- [B-industry.md](B-industry.md) — 18 primary vendor posts from Grammarly, Sudowrite, Jasper, Writer.com, Lavender, HubSpot, LiGo, and Anthropic (Claude Styles), covering how production writing tools capture and apply voice, the "Sea of Sameness" diagnosis, the emerging dual framing of humanization as both anti-detection and voice preservation, the 2025 shift to agentic voice enforcement, and the Grammarly Superhuman rebrand.
- [C-opensource.md](C-opensource.md) — 27 OSS repositories across five generations of tooling: decoding-time steering (PPLM, GeDi [archived 2025], FUDGE), neural style transfer (StyleTransformer, Styleformer, DualRL, StyIns), stylometry and anonymization (JStylo, Anonymouth, stylometric-transfer), LLM-era voice cloning (TinyStyler, StyleLLM, StyleTunedLM, Claude Code style skills), and new 2025 additions (EMNLP 2025 eval harness, SIGKDD authorship survey list, Profile-to-PEFT hypernetwork, Awesome-Personalized-LLMs).
- [D-commercial.md](D-commercial.md) — 19 products across four market segments — enterprise brand governance, marketing content suites, personal AI assistants and clones, and sales-coaching tools — with pricing, voice-capture mechanics, explicit gaps around individual (not brand) humanization, and 2025–2026 updates including Jasper's 69,500 Brand Voices, Grammarly's Superhuman rebrand and agentic agents, Claude Styles, and the copyright legal landscape post Anthropic's 2025 settlement.
- [E-practical.md](E-practical.md) — 29 practitioner posts from Reddit, Hacker News, LessWrong, Substack, and YouTube: the converged five-step voice-capture recipe, the "rejection profile beats preference profile" insight, lsusr's hyperbolic trick, the voice `.md` portable artifact pattern, a skeptic counter-current on disclosure, and 2025–2026 additions including the "blandification" framing and the Claude voice mode text-vs-audio distinction thread.
