Dataset Card for VCTK

Dataset Summary

This CSTR VCTK Corpus includes around 44-hours of speech data uttered by 110 English speakers with various accents. Each speaker reads out about 400 sentences, which were selected from a newspaper, the rainbow passage and an elicitation paragraph used for the speech accent archive.

Supported Tasks

  • automatic-speech-recognition, speaker-identification: The dataset can be used to train a model for Automatic Speech Recognition (ASR). The model is presented with an audio file and asked to transcribe the audio file to written text. The most common evaluation metric is the word error rate (WER).
  • text-to-speech, text-to-audio: The dataset can also be used to train a model for Text-To-Speech (TTS).

Dataset Structure

Data Instances

A data point comprises the path to the audio file, called file and its transcription, called text.

  'speaker_id': 'p225',
  'text_id': '001',
  'text': 'Please call Stella.',
  'age': '23',
  'gender': 'F',
  'accent': 'English',
  'region': 'Southern England',
  'file': '/datasets/downloads/extracted/8ed7dad05dfffdb552a3699777442af8e8ed11e656feb277f35bf9aea448f49e/wav48_silence_trimmed/p225/p225_001_mic1.flac',
      'path': '/datasets/downloads/extracted/8ed7dad05dfffdb552a3699777442af8e8ed11e656feb277f35bf9aea448f49e/wav48_silence_trimmed/p225/p225_001_mic1.flac',

      'sampling_rate': 48000
  'comment': ''

Each audio file is a single-channel FLAC with a sample rate of 48000 Hz.

Data Fields

Each row consists of the following fields:

  • speaker_id: Speaker ID
  • audio: Audio recording
  • file: Path to audio file
  • text: Text transcription of corresponding audio
  • text_id: Text ID
  • age: Speaker's age
  • gender: Speaker's gender
  • accent: Speaker's accent
  • region: Speaker's region, if annotation exists
  • comment: Miscellaneous comments, if any
