Kokoro voices — GGUF bundle

Per-speaker style packs for the Kokoro-82M family, converted to ggml's GGUF voice-pack format (arch= kokoro-voice , single F32 tensor voice.pack[max_phon, 1, 256] ). For use with CrispStrobe/CrispASR alongside cstr/kokoro-82m-GGUF or the German backbone cstr/kokoro-de-hui-base-GGUF .

Each voicepack is ~510 KB. Loading is direct passthrough — no quantisation needed at this size.

Voices

The Tundragoon voicepacks are [512, 1, 256] F32 (max_phon=512); the official Kokoro and kikiri voicepacks are [510, 1, 256] F32 (max_phon=510). The voice loader reads max_phon from the file so both layouts work transparently.

German voice cascade

When CrispASR is invoked with -l de (or any de_* / de-* locale) and no explicit --voice , it picks German voicepacks in this order:

1. df_victoria — kikiri-tts, in-distribution to the dida-80b German backbone (recommended)
2. df_eva — Tundragoon recovery, second-tier German speaker
3. ff_siwis — French baseline, last-resort non-silence fallback

Languages without a native pack (ru, ko, ar, …) fall back to ff_siwis . See cstr/kokoro-de-hui-base-GGUF for the matching German backbone.

Quality (ASR roundtrip)

Long German phrase ("Guten Tag, dies ist ein Test des deutschen Phonemizers."), parakeet-tdt-0.6b-v3 -l de , dida-80b backbone F16:

All four clear the energy gate (peak ≥ 8000, RMS ≥ 1000); two are word-perfect on a phrase the official English-trained Kokoro-82M with af_heart collapses to silence on.
