“…Dialect recognition can be performed on various levels, such as acoustic (e.g., spectral data), prosodic, phonotactical (e.g., language models) and lexical [21]. With regards to acoustic level, the spectral information of the speech signal is extracted through speech parameterization methods, and classification algorithms are then applied, such as a Gaussian mixture model [6], support vector model [22], and neural networks [23]. In [24], an acoustic approach is presented to recognize the four languages of India: Indian, English, Hindi, Assamese, Bengali.…”
