Contribution grade

Speech-translation architectures · Human-designed research method or resource

Reference score110,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Predicted subword text then discrete acoustic units in a jointly optimized two-pass model, with text-decoder pretraining and coordinated search.

Scientific scope

Predicted subword text then discrete acoustic units in a jointly optimized two-pass model, with text-decoder pretraining and coordinated search. Inherits discrete speech units, sequence translation and two-pass modeling. Direct uses the paper's joint-model definition and still includes intermediate text; vocoder is not jointly trained. Latency/ASR-BLEU are setup-specific.

Evidence
