transcription

Defines Modal GPU jobs for Whisper transcription

Transcription-Only

• Jobs return raw transcription

• LLM post-processing (SRT-Fixing) is applied by the Processor afterwards through the provider-agnostic LLM layer, so the same path works for both local and Modal transcription

transcribe_job(vol_fp, vol_id, output_format='srt', *, w_model_args=None, w_transcribe_args=None)

Transcribe media on a Modal GPU and return raw SRT content

output_format

• When output_format="srt", sentence-level SRT content is composed from transcription segments, returning a string ready to be saved as a .srt file

• When output_format="joined", transcription segment texts are joined with the Japanese full stop into a single string without any timing information

File Transfer

• The input media is read out of the per-job ephemeral volume into a container-local temp directory before being handed to Whisper

• That directory is removed once the job finishes

Parameters:

Name	Type	Description	Default
vol_fp	str	Path of the input media inside the per-job ephemeral volume	required
vol_id	str	ID of the per-job ephemeral volume	required
output_format	Literal['srt', 'joined']	srt for sentence-level SRT content, joined for a single joined string. Defaults to srt	'srt'
w_model_args	dict | None	Additional arguments for WhisperModel. Overrides the ones set in mirumoji.server.processing.whisper.DEFAULT_MODEL_OPTS	None
w_transcribe_args	dict | None	Additional arguments for WhisperModel.transcribe. Overrides the ones set in mirumoji.server.processing.whisper.DEFAULT_TRANSCRIBE_OPTS	None

Returns:

Type	Description
str	The raw transcription as SRT content

Raises:

Type	Description
ModalVolumeError	If the input can't be read from the volume
WhisperUnavailableError	If the model can't be loaded
TranscriptionError	If transcription fails
