A method and system for improving speech quality may include estimating at least one component of a distorted portion of a speech signal from at least one component of an undistorted portion of the speech signal and reinforcing the component of the distorted portion based on the estimating. The components may include the pitch, spectral envelope and spectral energy of the speech signal. The undistorted portion of the speech signal may be delayed and the components of the distorted portion may be interpolated from the components of a delayed undistorted portion and a current undistorted portion of the speech signal. The components of the distorted portion of the speech signal may be extrapolated from a current undistorted portion of the speech signal. Components of the distorted portion of the speech signal may be estimated from frequency bands other than the frequency band affected by the distortion.
A method for processing signals, the method comprising:
A machine-readable storage having stored thereon, a computer program having at least one code section for processing signals, the at least one code section being executable by a machine for causing the machine to perform steps comprising:
A system for processing signals, the system comprising:
A method for processing signals, the method comprising, replacing a frequency component that matches a background noise estimate of a speech signal with an estimate derived from a signal that is characteristic of said background noise estimate.
A system for processing signals, the system comprising, one or more circuits that replace a frequency component that matches a background noise estimate of a speech signal with an estimate derived from a signal that is characteristic of said background noise estimate.
