Background
Whisper's
transcribe()
struggles with contextual proper nouns if they appear after the initial prompt has been consumed; see some experimental results here. This solves that issue by allowing the initial "context" prompt to be carried as the sliding window moves through the audio.Changes
Add an option
carry_initial_prompt = False
towhisper.transcribe()
.When
carry_initial_prompt
is set toTrue
,initial_prompt
is prepended to each internaldecode()
call'sprompt
. If there is not enough context space at the start of the prompt, the prompt is left-sliced to make space.
