A huge amount of research has been done in the field speech signal processing recent years. In particular, there increasing interest automatic recognition (ASR) technology field. ASR began with simple systems that responded to a limited number sounds and evolved into sophisticated respond fluently natural language. This systematic review is provided help other researchers most significant topic...
Abstract Automatic speech recognition (ASR) could potentially improve communication by providing transcriptions of in real time. ASR is particularly useful for people with progressive disorders that lead to reduced intelligibility or difficulties performing motor tasks. services are usually trained on healthy and may not be optimized impaired speech, creating a barrier accessing augmented assis...
The performance of automatic speech recognition (ASR) systems is adversely affected by the variations in speakers, audio channels and environmental conditions. Making these systems robust to these variations is still a big challenge. One of the main sources of variations in the speakers is the differences between their Vocal Tract Length (VTL). Vocal Tract Length Normalization (VTLN) is an effe...
The Mel Frequency cepstral coefficients are the most widely used feature in speech recognition but they are very sensitive to noise. In this paper to achieve a satisfactorily performance in Automatic Speech Recognition (ASR) applications we introduce a noise robust new set of MFCC vector estimated through following steps. First, spectral mean normalization is a pre-processing which applies to t...
