I am trying to create a domain template, I have about 700 audio files, they are all: mono / 16kHz / 16bit.
I created 3 csv files in which I inserted file_path, file_size, transcript
, dividing the audio files into 70% train, 20% dev, 10% test. I created an alphabet that contains all the characters present in the transcriptions.
I trained the model using this command:
python3 DeepSpeech.py \
--train_files /test/csvFile/train.csv \
--dev_files /test/csvFile/dev.csv \
--test_files /test/csvFile/test.csv \
--export_dir /test/model/ \
--alphabet_config_path /test/alphabet.txt
During the training phase there are no errors or problems, after finishing the training the model only returns empty strings like this
+What should I do, has anyone already had this problem?
