METHOD AND SYSTEM FOR RECONSTRUCTING SPEECH FROM AN INPUT SIGNAL COMPRISING WHISPERS
First Claim
1. A system for reconstructing speech from an input signal comprising whispers, the system comprising:
- an analysis unit configured to analyse the input signal to form a representation of the input signal;
an enhancement unit configured to modify the representation of the input signal to adjust a spectrum of the input signal, wherein the adjusting of the spectrum of the input signal comprises modifying a bandwidth of at least one formant in the spectrum to achieve a predetermined spectral energy distribution and amplitude for the at least one formant; and
a synthesis unit configured to reconstruct speech from the modified representation of the input signal.
