summary: |
  Offline multilingual speech-to-text and translation. An 883M-parameter
  multitask AED with a 32-layer FastConformer encoder and a 4-layer
  Transformer decoder. Supports automatic speech recognition in English,
  German, Spanish, and French, and bidirectional EN↔{DE, ES, FR}
  translation. Takes a
  16 kHz mono WAV and produces a transcript. Not a streaming model;
  word/segment timestamps are upstream-experimental and not exposed in
  the v1 port.
