  Automatic Speech Recognition (ASR), as an interesting field of speech
processing, is utilized in real applications and is implemented using various
techniques amongst which the artificial neural network is the most popular.
Increasing the performance, making these systems robust to noise and developing
this technology for low-resource languages is among the current challenges.
This paper addresses the development of an ASR system for the Central Kurdish
language (CKB), as a low-resource language, using end to end transformers.
Kurdish, as an Indo-European language, is categorized into three main dialects,
i.e., Central Kurdish (i.e., Sorani), North Kurdish (Kirmanji), and South
Kurdish which is spoken by more than 30 million people. In this research, a
speech corpus of size 224 hours is collected using various sources. Then, this
corpus is used to train the transformer-based acoustic model. A transfer
learning technique is also utilized in training acoustic models. As a result of
these efforts, our optimal model attains state-of-the-art results on the
Asosoft test set, achieving a Word Error Rate (WER) of 13%. This accomplishment
signifies a notable advancement in ASR technology for the Central Kurdish
language, particularly in the context of low-resource languages.
