Claims (5)
1. Fremgangsmåde til forbedring af talekvaliteten af en elektro-larynx (EL) højttaler, hvis talesignal S(w,t) digitaliseres ved hjælp af egnede midler, kendetegnet ved de følgende trin: a) at opdele et talesignal S(w,t) med én kanal, hvilket talesignal består af summen af komposanterne af en tidsvariant del x(w)H(w,t) og en tidsinvariant del x(w)H(w), i en række frekvenskanaler ved at overføre tidsdomænet i et diskret frekvensdomæne, b) at frafiltrere den tidsinvariante del x(w)H(w) ved at frafiltrere modulationsfrekvensen 0 Hz ved hjælp af et højpas- eller notchfilter i hver frekvenskanal, og c) at tilbagetransformere det filtrerede talesignal fra frekvensdomænet til tidsdomænet og at sammenføre til et udgangssignal med én kanal.
2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at overførslen af talesignalet i trin a) sker ved hjælp af Fourier-transformation, og at tilbagetransformationen i trin c) sker ved invers Fourier-transformation.
3. Fremgangsmåde ifølge krav 1, kendetegnet ved, at overførslen af talesignalet i trin a) og syntesen af frekvenskanalerne i trin c) sker med en filterbank.
4. Fremgangsmåde ifølge ét af kravene 1 til 3, kendetegnet ved, at der før filtreringen i trin b) sker en signalkomprimering, og efter trin b) en dekomprimering.
5. Fremgangsmåde ifølge ét af kravene 1 til 4, kendetegnet ved, at der før tilbagetransformationen i trin c) sker en ensretning af de negative signalkomponenter.
