CrispASR's piper backend phonemizes non-English text via espeak-ng (dlopen,
the MIT-clean path; English uses a built-in G2P). The FROM scratch crispasr
image shipped none of it, so non-English piper voices loaded but failed
synthesis with "phonemization failed". Bundle the espeak-ng runtime so they
work:
- Dockerfile.golang: install espeak-ng-data + libespeak-ng1 and its libpcaudio0
/ libsonic0 deps in the crispasr builder (espeak's dlopen fails without the
latter two).
- package.sh: copy libespeak-ng.so.1, libpcaudio.so.0, libsonic.so.0 into
package/lib/ and the espeak-ng-data dir into the package root.
- run.sh: export CRISPASR_ESPEAK_DATA_PATH so the bundled data is found.
Add 9 single-speaker piper voices (de/en/it, incl. Italian paola + riccardo) to
the gallery, run through backend:piper, hosted at
LocalAI-Community/piper-voices-GGUF (converted from rhasspy/piper-voices with
CrispASR's convert-piper-to-gguf.py). Only single-speaker low/medium voices are
included; the engine does not yet support multi-speaker or high-quality piper
decoders.
All 9 verified end-to-end: each synthesizes a WAV at the model's native sample
rate using only the image-bundled espeak payload.
