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 ### Languages Dhivehi ## 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. #### Who are the source language producers? [More Information Needed] ### Personal and Sensitive Information [More Information Needed] ## Considerations for Using the Data ### Social Impact of Dataset [More Information Needed] ### Discussion of Biases [More Information Needed] ### Other Known Limitations [More Information Needed] ## Additional Information ### Dataset Curators [More Information Needed] ### Licensing Information [More Information Needed] ### Citation Information ``` @misc{Javaabu_2023, title = "Dhivehi Shaafiu Speech Dataset", url = "https://huggingface.co/datasets/javaabu/dhivehi-shaafiu-speech", journal = "Hugging Face", author = {{Javaabu Pvt.
