benjamin-paine/dinner-party-corpus

This repository contains a reorganized, utterance-focused version of the Dinner Party Corpus, released by Amazon, the Center for Language and Speech Processing (CLSP) and Johns Hopkins University in September 2019.

Description

The following description is provided in arXiv 1909.13447:

We present a speech data corpus that simulates a "dinner party" scenario taking place in an everyday home environment. The corpus was created by recording multiple groups of four Amazon employee volunteers having a natural conversation in English around a dining table. The participants were recorded by a single-channel close-talk microphone and by five far-field 7-microphone array devices positioned at different locations in the recording room. The dataset contains the audio recordings and human labeled transcripts of a total of 10 sessions with a duration between 15 and 45 minutes. The corpus was created to advance in the field of noise robust and distant speech processing and is intended to serve as a public research and benchmarking data set.

License

As stated in the paper linked above, section 4, the dataset is released under the CDLA-Permissive license.

Comparison to Base Dataset

• The base dataset was downloaded from Zenodo, this has a compressed size of 12.4GB, and an uncompressed size of 23GB. It is organized in manner to minimize file size and data repetition, with uncut audio and separate label files.
• This dataset has an uncompressed size of 27GB, making it about 15% larger than the uncompressed base dataset. For this size exchange, you gain ease-of-use; all audio is pre-cut to the start and end utterances, and mapped with the appropriate labels directly in Parquet.

How to Use

This repository is made to be used with 🤗Datasets.

from datasets import load_dataset

dataset = load_dataset(
    "benjamin-paine/dinner-party-corpus",
    config_name="split-channel", # 'split-channel' or 'mixed-channel'
    split="train" # 'train' or 'test'
)

for datum in dataset:
    # Do something with the audio
    # datum["audio"]["array"] is the sample waveform at 16khz (see datum["audio"]["sampling_rate"])
    pass

Conversion Script

The script used to convert the data is available in this repository as convert.py.
