Warped linear prediction (WLP) in speech and audio processing
In this paper linear prediction process is applied to frequency warped signals. The warping is realized by using orthonormal FAM' functions. The general formulation of WLP is given and effective realizations with allpass filters are studied. The application of auditory WLP to speech coding and speech recognition has given good results.
متن کاملSpeech synthesis using warped linear prediction and neural networks
A text-to-speech synthesis technique, based on warped linear prediction (WLP) and neural networks, is presented for high-quality individual sounding synthetic speech. Warped linear prediction is used as a speech production model with wide audio bandwidth yet with highly compressed control parameter data. An excitation codebook, inverse filtered from a target speaker’s voice, is applied to obtai...
متن کاملAuditory Interpretation and Application of Warped Linear Prediction
This paper presents a study on a specific signal processing technique, the warped linear prediction (WLP), interpreted here from an auditory perception point of view. WLP is a signal modeling technique that can approximate the frequency resolution properties of the human ear. WLP is shown in this paper to have system-level similarities with signal analysis found in the peripheral auditory syste...

15 صفحه اولA warped linear-prediction-based subband audio coding algorithm
In this paper, a novel audio coding algorithm is proposed where the warped linear prediction (WLP) technique is employed to construct a perceptual preand post-filter for subband audio coding. A modified signal-to-mask ratio (SMR) calculation is given for subband coding of the WLP residuals of audio signals. The concept of perceptual entropy (PE) is extended to subband coding, resulting in the s...
