Bandwidth Extension of Speech Signals describes the theory and methods for quality enhancement of clean speech signals and distorted speech signals such as those that have undergone a band limitation, for instance, in a telephone network. Problems and the respective solutions are discussed for the different approaches. The different approaches are evaluated and a real-time implementation of the most promising approach is presented. The book includes topics related to speech coding, pattern- / speech recognition, speech enhancement, statistics and digital signal processing in general. Includes a joint, unified and comprehensive presentation of speech signal analysis techniques Proposes ready-to-use methods for the bandwidth extension of speech signals in real-world scenarios Describes objective and subjective evaluation results for the presented approaches

   INDICE: Introduction.- Speech Generation.- Properties and Features of Speech Signals.- Excitation Signal Extension.- Broadband Spectral Envelope Estimation.- Quality Evaluation.- Summary.
