wav2vec2-xls-r-300m-cv7-turkish
Model description
This ASR model is a fine-tuned version of facebook/wav2vec2-xls-r-300m on Turkish language.
Training and evaluation data
The following datasets were used for finetuning:
- Common Voice 7.0 TR All
validated
split excepttest
split was used for training. - MediaSpeech
Training procedure
To support both of the datasets above, custom pre-processing and loading steps was performed and wav2vec2-turkish repo was used for that purpose.

Language Model
N-gram language model is trained on a Turkish Wikipedia articles using KenLM and ngram-lm-wiki repo was used to generate arpa LM and convert it into binary format.
Evaluation Commands
Please install unicode_tr package before running evaluation. It is used for Turkish text processing.
