EVI

EVI is a challenging spoken multilingual dataset with 5,506 dialogues in English, Polish, and French that can be used for benchmarking and developing knowledge-based enrolment, identification, and identification for spoken dialogue systems.

Example

EVI can be downloaded and used as follows:

from datasets import load_dataset
evi = load_dataset("PolyAI/evi", "en-GB") # for British English

# to download data from all locales use:
# evi = load_dataset("PolyAI/evi", "all")

# see structure
print(evi)

Dataset Structure

We show detailed information of the example for the en-GB configuration of the dataset. All other configurations have the same structure.

Data Instances

An example of a data instance of the config en-GB looks as follows:

{
    "language": 0,
    "dialogue_id": "CA0007220161df7be23f4554704c8720f5",
    "speaker_id": "e80e9bdd33eda593f16a1b6f2fb228ff",
    "turn_id": 0,
    "target_profile_id": "en.GB.608",
    "asr_transcription": "w20 a b",
    "asr_nbest'": ["w20 a b", "w20 a bee", "w20 a baby"],
    "path": "audios/en/CA0007220161df7be23f4554704c8720f5/0.wav",
    "audio": {
        "path": "/home/georgios/.cache/huggingface/datasets/downloads/extracted/0335ebc25feace53243133b49ba17ba18e26f0f97cb083ffdf4e73dd7427b443/audios/en/CA0007220161df7be23f4554704c8720f5/0.wav",
        "array": array([ 0.00024414,  0.00024414,  0.00024414, ...,  0.00024414,
       -0.00024414,  0.00024414], dtype=float32),
       "sampling_rate": 8000,
    }
}

Data Fields

The data fields are the same among all splits.

  • language (int): ID of language
  • dialogue_id (str): the ID of the dialogue
  • speaker_id (str): the ID of the speaker
  • turn_id (int)": the ID of the turn
  • target_profile_id (str): the ID of the target profile
  • asr_transcription (str): ASR transcription of the audio file
  • asr_nbest (list): n-best ASR transcriptions of the audio file
  • path (str): Path to the audio file
  • audio (dict): Audio object including loaded audio array, sampling rate and path of audio

Data Splits

Every config only has the "test" split containing ca. 1,800 dialogues.
