	  'sampling_rate': 16000},
  'sentence': 'Panonton ting haruleng ningali Kelly Clarkson keur nyanyi di tipi',
}
```

### Data Fields

- `path`: The path to the audio file.
- `audio`: 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]`.
- `sentence`: The sentence the user was prompted to speak.

### Data Splits

There is only one "train" split for all configurations and the number of examples are:

### Dataset Summary


OpenSLR is a site devoted to hosting speech and language resources, such as training corpora for speech recognition,
and software related to speech recognition. Currently, following resources are available:


#### SLR32: High quality TTS data for four South African languages (af, st, tn, xh).


This data set contains multi-speaker high quality transcribed audio data for four languages of South Africa.
The data set consists of wave files, and a TSV file transcribing the audio. In each folder, the file line\_index.tsv
contains a FileID, which in turn contains the UserID and the Transcription of audio in the file.


The data set has had some quality checks, but there might still be errors.


This data set was collected by as a collaboration between North West University and Google.

Dataset Structure

### Data Fields


* 'path': The path to the audio file.
* 'audio': 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]'.
* 'sentence': The sentence the user was prompted to speak.


### Data Splits


There is only one "train" split for all configurations and the number of examples are:

Dataset Structure
----------------- ### Data Instances


A typical data point comprises the path to the audio file, called path and its sentence. #### SLR32, SLR35, SLR36, SLR41, SLR42, SLR43, SLR44, SLR52, SLR53, SLR54, SLR63, SLR64, SLR65, SLR66, SLR69, SLR70, SLR71, SLR72, SLR73, SLR74, SLR75, SLR76, SLR77, SLR78, SLR79, SLR80, SLR86 ### Data Fields


* 'path': The path to the audio file.
* 'audio': 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]'.
* 'sentence': The sentence the user was prompted to speak. ### Data Splits


There is only one "train" split for all configurations and the number of examples are:

Dataset Structure
-----------------### Data Instances


A typical data point comprises the path to the audio file, called path and its sentence. passage: #### SLR32, SLR35, SLR36, SLR41, SLR42, SLR43, SLR44, SLR52, SLR53, SLR54, SLR63, SLR64, SLR65, SLR66, SLR69, SLR70, SLR71, SLR72, SLR73, SLR74, SLR75, SLR76, SLR77, SLR78, SLR79, SLR80, SLR86### Data Fields


* 'path': The path to the audio file.
* 'audio': 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]'.
* 'sentence': The sentence the user was prompted to speak.### Data Splits


There is only one "train" split for all configurations and the number of examples are:
