## Dataset Structure

### Data Instances

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

```json
{
  '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.

|                  | Train    | Validation | Test     | Total    |
| ---------------- |----------|------------|----------|----------|
| Utterances       | 6657     | 832        | 832      | 8321     |
| Duration         | 13:30:13 | 01:44:36   | 01:40:15 | 16:55:04 |

## Dataset Creation

### Curation Rationale

[More Information Needed]

### 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.
