Example Usage

There are 'train', 'test_freq', 'test_rare', 'valid_freq', and 'valid_rare' splits. Below is an example usage.

from datasets import load_dataset

MultiD = load_dataset("IVLLab/MultiDialog", "valid_freq", use_auth_token=True)

# see structure
print(MultiD)

# load audio sample on the fly
audio_input = MultiD["valid_freq"][0]["audio"]  # first decoded audio sample
transcription = MultiD["valid_freq"][0]["value"]  # first transcription

Supported Tasks

multimodal dialogue generation : The dataset can be used to train an end-to-end multimodal
automatic-speech-recognition: The dataset can be used to train a model for Automatic Speech Recognition (ASR).
text-to-speech: The dataset can also be used to train a model for Text-To-Speech (TTS).

Languages

Multidialog contains audio and transcription data in English.

Gold Emotion Dialogue Subset

We provide a gold emotion dialogue subset in the MultiDialog dataset, a more reliable resource for studying emotional dynamics in conversations. We classify dialogues from actors that exhibit emotion accuracy above 40% as gold emotion dialogue. Please use dialogues from actors with the following ids: a, b, c, e, f, g, i, j, and k.

Data Fields

file_name (string) - relative file path to the audio sample in the specific split directory.
conv_id (string) - unique identifier for each conversation.
utterance_id (float) - uterrance index.
from (string) - who the message is from (human, gpt).
audio (Audio feature) - a dictionary containing the path to the audio, the decoded audio array, and the sampling rate. In non-streaming mode (default), the path point to the locally extracted audio. In streaming mode, the path is the relative path of an audio. segment inside its archive (as files are not downloaded and extracted locally).
value (string) - transcription of the utterance.
emotion (string) - the emotion of the utterance.
original_full_path (string) - the relative path to the original full audio sample in the original data directory.

Emotion is assigned from the following labels: "Neutral", "Happy", "Fear", "Angry", "Disgusting", "Surprising", "Sad"
