The recorded background noise level in the chamber was 22 dB. The sampling rate and bit resolution were set to 16 kHz and 16 bps for normal high quality used in automatic speech recognition applications.
Instead, this paper presents experimental methods by means of acoustical analysis and machine learning techniques. In order to enhance the performance of accent classiﬁer to classify the Malay, Chinese, and Indian accents this paper proposes fusion techniques of popularly known mel-frequency cepstral coefﬁcients (MFCC) and linear prediction coefﬁcients (LPC) with formants termed here as spectral feature fusions (SFFs). In these SFFs feature extractors, the main spectral features are fused with ﬁve usable formants and the extracted features are used to model K-nearest neighbors and artiﬁcial neural networks (ANN).
