langchain_community.document_loaders.parsers.audio.OpenAIWhisperParserLocal¶

class langchain_community.document_loaders.parsers.audio.OpenAIWhisperParserLocal(device: str = '0', lang_model: Optional[str] = None, forced_decoder_ids: Optional[Tuple[Dict]] = None)[source]¶

Transcribe and parse audio files with OpenAI Whisper model.

Audio transcription with OpenAI Whisper model locally from transformers.

Parameters: device - device to use

NOTE: By default uses the gpu if available, if you want to use cpu, please set device = “cpu”

lang_model - whisper model to use, for example “openai/whisper-medium” forced_decoder_ids - id states for decoder in multilanguage model,

usage example: from transformers import WhisperProcessor processor = WhisperProcessor.from_pretrained(“openai/whisper-medium”) forced_decoder_ids = WhisperProcessor.get_decoder_prompt_ids(language=”french”,

task=”transcribe”)

forced_decoder_ids = WhisperProcessor.get_decoder_prompt_ids(language=”french”, task=”translate”)

Initialize the parser.

Parameters
  • device – device to use.

  • lang_model – whisper model to use, for example “openai/whisper-medium”. Defaults to None.

  • forced_decoder_ids – id states for decoder in a multilanguage model. Defaults to None.

Methods

__init__([device, lang_model, ...])

Initialize the parser.

lazy_parse(blob)

Lazily parse the blob.

parse(blob)

Eagerly parse the blob into a document or documents.

__init__(device: str = '0', lang_model: Optional[str] = None, forced_decoder_ids: Optional[Tuple[Dict]] = None)[source]¶

Initialize the parser.

Parameters
  • device – device to use.

  • lang_model – whisper model to use, for example “openai/whisper-medium”. Defaults to None.

  • forced_decoder_ids – id states for decoder in a multilanguage model. Defaults to None.

lazy_parse(blob: Blob) Iterator[Document][source]¶

Lazily parse the blob.

parse(blob: Blob) List[Document]¶

Eagerly parse the blob into a document or documents.

This is a convenience method for interactive development environment.

Production applications should favor the lazy_parse method instead.

Subclasses should generally not over-ride this parse method.

Parameters

blob – Blob instance

Returns

List of documents
