Live Translator — Offline Model Packs

On-demand offline model packs for the Live Translator app. Downloaded per language pair; the shared common/ bundle installs once on the first pair.

Pipeline / runtimes

ASR: Whisper tiny int8 via sherpa-onnx (onnxruntime).
NMT: CTranslate2 int8 (OPUS-MT / Marian). Requires the CT2 runtime on device (dart:ffi → libctranslate2). Tokenize with the .spm SentencePiece models; decode with beam search (beam=5, no-repeat-ngram, length penalty). Feed one sentence per call — Marian emits a single sentence per translate.
TTS: Kokoro int8 (sherpa-onnx) for en/es/…; Piper medium for Greek.
