Ponybook TTS — 58-voice audiobook model
The TTS model behind Ponybook, a self-hosted audiobook reader that casts book characters to voices automatically. 58 speakers: the My Little Pony cast (mane six, princesses, students, side characters), the Team Fortress 2 cast (useful stand-ins when no pony fits a gruff or adult character), and a dedicated Anon voice for second-person fics. 12-class emotion conditioning with continuous energy and strength controls.
This is a fan-made fine-tune derived from ZDisket/MOSS-TTS-PNY (itself built on OpenMOSS MOSS-TTS), extended with additional characters and a delivery/pronunciation adapter. Voices are trained from show audio: non-commercial, personal use.

the 58-speaker codec-LM checkpoint (bf16, ~5.6 GB) |

inference runtime + speaker_id_map.csv (the speaker roster this checkpoint's embedding table matches) |
voice_patch/ |
LoRA delivery/pronunciation adapter — strongly recommended (the server blends it per speaker at runtime; without it /blend is disabled and delivery is flatter) |
Not included (unmodified, pulled from the base repo by the Ponybook
setup script): the MOSS audio codec (moss_audio_tokenizer/) and the
iSTFTNet vocoder — download them from
ZDisket/MOSS-TTS-PNY.
Use
Don't wire this up by hand — use the Ponybook repo's tts-server/:
setup.sh downloads everything into place and run_server.sh serves a
simple HTTP TTS API (FastAPI: /tts, /speakers, /health) on an
NVIDIA GPU (~9–12 GB VRAM default preset, lighter presets available).
Speaker ids are positional: speaker_id_map.csv and the checkpoint's
embedding table must always travel together, and the voice_patch/
adapter matches this exact checkpoint.
