Converts flac to wav and build manifests's json
Args:
text_path: source with text lines
dst_folder: where wav files will be stored
vocab_size: vocabular size used in encoding the text
tokenizer_type: type of tokenization to perform - wpe or spe
spe_type: type of tokenization model used for spe.
spe_character_coverage: float value between 0 and 1 (as a percentage). For languages with a vast charset,
can be < 1.0, but for all other languages, it should be set as 1.0
spe_sample_size: int, default of -1. If positive integer is used, samples the dataset
by given sample size.
spe_train_extremely_large_corpus: bool. If dataset is too large, and user has sufficient RAM,
this flag can be set to try to trained the tokenizer. Will silently fail if it runs out of RAM.
spe_max_sentencepiece_length: Limits the maximum length of the SentencePiece subword that can be constructed.
By default, no limit is placed.
spe_bos: Bool flag, whether to add <s> to SentencePiece tokenizer vocabulary.
spe_eos: Bool flag, whether to add </s> to SentencePiece tokenizer vocabulary.
spe_pad: Bool flag, whether to add <pad> to SentencePiece tokenizer vocabulary.
lower_case: whether to tokenize with lower case character set only (for english)
