Query: Multi-Dialect Arabic Speech Recognition   This paper presents the design and development of multi-dialect automatic
speech recognition for Arabic. Deep neural networks are becoming an effective
tool to solve sequential data problems, particularly, adopting an end-to-end
training of the system. Arabic speech recognition is a complex task because of
the existence of multiple dialects, non-availability of large corpora, and
missing vocalization. Thus, the first contribution of this work is the
development of a large multi-dialectal corpus with either full or at least
partially vocalized transcription. Additionally, the open-source corpus has
been gathered from multiple sources that bring non-standard Arabic alphabets in
transcription which are normalized by defining a common character-set. The
second contribution is the development of a framework to train an acoustic
model achieving state-of-the-art performance. The network architecture
comprises of a combination of convolutional and recurrent layers. The
spectrogram features of the audio data are extracted in the frequency vs time
domain and fed in the network. The output frames, produced by the recurrent
model, are further trained to align the audio features with its corresponding
transcription sequences. The sequence alignment is performed using a beam
search decoder with a tetra-gram language model. The proposed system achieved a
14% error rate which outperforms previous systems.
