|
|
|
|
|
### Dataset Summary |
|
|
|
Dhivehi Shaafiu Speech is a single speaker Dhivehi speech dataset created by [Javaabu Pvt. Ltd.](https://javaabu.com). |
|
|
|
The dataset contains around 16.5 hrs of text read by professional Maldivian narrator Muhammadh Shaafiu. |
|
The text used for the recordings were text scrapped from various Maldivian news websites. |
|
|
|
### Supported Tasks and Leaderboards |
|
|
|
- Automatic Speech Recognition |
|
- Text-to-Speech |
|

## 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. |

|
### 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. |
|
