Dataset Structure

Data Instances

A typical data point comprises the path to the audio file and its sentence.

{
  'path': 'dhivehi-shaafiu-speech-train/waves/shafiu_1_d35e8g63.wav',  
  'sentence': 'ކަމަށާއި އެކަކު އަނެކަކައް އަނގައިގެން ނުބުނާކަމަށް އޭނާ ވިދާޅުވިއެވެ.',
  'audio': {
    'path': 'dhivehi-shaafiu-speech-train/waves/shafiu_1_d35e8g63.wav', 
    'array': array([-0.00048828, -0.00018311, -0.00137329, ...,  0.00079346, 0.00091553,  0.00085449], dtype=float32), 
    'sampling_rate': 16000
  }, 
}

Data Fields

  • path (string): The path to the audio file.

  • sentence (string): The transcription for the audio file.

  • audio (dict): A dictionary containing the path to the downloaded audio file, the decoded audio array, and the sampling rate. Note that when accessing the audio column: dataset[0]["audio"] the audio file is automatically decoded and resampled to dataset.features["audio"].sampling_rate. Decoding and resampling of a large number of audio files might take a significant amount of time. Thus it is important to first query the sample index before the "audio" column, i.e. dataset[0]["audio"] should always be preferred over dataset["audio"][0].

Data Splits

The speech material has been subdivided into portions for train, test and validation.

Source Data

Initial Data Collection and Normalization

Data was collected through the AduEhy TTS Management System developed Javaabu. The narrator was shown text snippets one at a time, which were then read and recorded through the browser. Only minimal text normalization has been performed, which involved replacing multiple whitespaces and new lines with single spaces.
