	# Composite dataset for Spanish made from public available data
	This dataset is composed of the following public available data:

	## Train split:
	The train split is composed of the following datasets combined:
	- mozilla-foundation/common_voice_18_0/es: "validated" split removing "test_cv" and "dev_cv" split's sentences. (validated split contains official train + dev + test splits and more unique data)
	- openslr: a train split made from the SLR(39,61,67,71,72,73,74,75,108) subsets, this split has been cleaned from acronyms, numbers and sentences that are repeated in the following "test_oslr" and "dev_oslr" splits.
	- mls/es: the "train" split from the spanish dataset of Multilingual Librispeech.
	- facebook/voxpopuli/es: the "train" split from the spanish voxpopuli dataset, cleaned from acronyms and numeric characters.
	- gttsehu/basque_parliament_1/es: the official "train_clean" split.
	The Total hours and sentences is slightly smaller because some of the sentences were removed due to be repeated in some of the test and dev splits.
	\| Split tag \| Source \| Hours \| Sentences \|
	\|:---------:\|:--------------------:\|:-------------:\|:-----------:\|
	\| - \| common_voice_18_0 \| 538.82 h \| 378560 \|
	\| - \| openslr \| 45.58 h \| 24460 \|
	\| - \| mls \| 922.47 h \| 221855 \|
	\| - \| voxpopuli \| 142.96 h \| 48667 \|
	\| - \| basque_parliament_1 \| 949.27 h \| 469937 \|
	\| train \| Total \| 2596.32 h \| 1142586 \|

	## Test splits:
	Those test splits are separated, and it is recommended to not evaluate them together in a single split:
	- mozilla-foundation/common_voice_18_0/es: the official "test" split.
	- openslr: a test split made from the SLR(39,61,67,71,72,73,74,75,108) subsets, this split has been cleaned from acronyms, numbers and sentences.
	- mls/es: the "test" split from the spanish dataset of Multilingual Librispeech.
	- facebook/voxpopuli/es: the "test" split from the spanish voxpopuli dataset, cleaned from acronyms and numeric characters.
	- gttsehu/basque_parliament_1/es: the official "test" split.
	\| Split tag \| Source \| Hours \| Sentences \|
	\|:---------:\|:--------------------:\|:-------------:\|:-----------:\|
	\| test_cv \| common_voice_18_0 \| 26.84 h \| 15872 \|
	\| test_oslr \| openslr \| 7.03 h \| 4107 \|
	\| test_mls \| mls \| 10 h \| 2385 \|
	\| test_vp \| voxpopuli \| 4.64 h \| 1446 \|
	\| test_parl \| basque_parliament_1 \| 6.56 h \| 3450 \|
	\| \| Total \| 55.07 h \| 27260 \|

	## Dev splits:
	There is a dev split composed by 5 dev subsplits that are also independently accesible. It is recommended to use the combined "dev" split for development tasks since it is accurately balanced in number of hours (~5h each, a total of ~25h).
	- mozilla-foundation/common_voice_18_0/es: a small dev split made from the official "dev" split.
	- openslr: a small dev split made from the SLR(39,61,67,71,72,73,74,75,108) subsets, this split has been cleaned from acronyms, numbers and sentences.
	- mls/es: a small "dev" split from the original "dev" split from spanish dataset of Multilingual Librispeech.
	- facebook/voxpopuli/es: the original "dev" split from the spanish voxpopuli dataset, cleaned from acronyms and numeric characters.
	- gttsehu/basque_parliament_1/es: the official "dev" split.
	\| Split tag \| Source \| Hours \| Sentences \|
	\|:---------:\|:--------------------:\|:-------------:\|:-----------:\|
	\| dev_cv \| common_voice_18_0 \| 5.03 h \| 3000 \|
	\| dev_oslr \| openslr \| 5.13 h \| 3063 \|
	\| dev_mls \| mls \| 5.09 h \| 1223 \|
	\| dev_vp \| voxpopuli \| 4.89 h \| 1564 \|
	\| dev_parl \| basque_parliament_1 \| 4.81 h \| 2567 \|
	\| dev \| Total \| 24.95 h \| 11417 \|
