ASR text preprocessing utility

install

pip install asrp

Preprocess

input: dictionary, with key sentence
output: preprocessed result, inplace handling.

import asrp

batch_data = {
    'sentence': "I'm fine, thanks."
}
asrp.fun_en(batch_data)

dynamic loading

import asrp

batch_data = {
    'sentence': "I'm fine, thanks."
}
preprocessor = getattr(asrp, 'fun_en')
preprocessor(batch_data)

Evaluation

import asrp

targets = ['HuggingFace is great!', 'Love Transformers!', 'Let\'s wav2vec!']
preds = ['HuggingFace is awesome!', 'Transformers is powerful.', 'Let\'s finetune wav2vec!']
print("chunk size WER: {:2f}".format(100 * asrp.chunked_wer(targets, preds, chunk_size=None)))
print("chunk size CER: {:2f}".format(100 * asrp.chunked_cer(targets, preds, chunk_size=None)))

Speech to Hubert code

import asrp

Hubert code to speech

import asrp

code = []  # discrete unit
# download tts checkpoint and waveglow_checkpint from https://github.com/pytorch/fairseq/tree/main/examples/textless_nlp/gslm/unit2speech
cs = asrp.Code2Speech(tts_checkpoint='./tts_checkpoint_best.pt', waveglow_checkpint='waveglow_256channels_new.pt')
