Transcription & speech recognition
Greedy decoding
Greedy decoding is the fastest way for a speech model to produce text: at every step it emits the single most probable next token, never revisiting earlier choices.
Greedy decoding is standard when speed matters — live captions, quick drafts — and its errors are usually local. Beam search reconsiders alternatives and wins on ambiguous audio at a compute cost.
