Construction of a database for speech recognition of isolated Arabic words

Automatic speech recognition for the Arabic language is a field that is in a current remarkable development and still attracts many researchers who try to improve year after year the recognition rate. Many works, nowadays, have been focused on automatic speech recognition (ASR) for the Arabic language. The paper presents the significance of the ASR systems built in the past few years. This work also aims to introduce a new Arabic database for isolated word by defining a new concept of phonetic units: semi-syllable units. Thus, the corpus contains a collection of semi-syllable audio files as well as their corresponding transcription files. This database will help us in future works.
