Abstract  Abstract

1. A device containing! a first speech encoder configured to encode a low frequency band speech signal; ! a second speech encoder, configured to encode the speech signal of the high frequency band; and! a filter bank having (A) a low frequency band processing path configured to receive a broadband speech signal having a frequency spectrum of at least between 1000 and 6000 Hz and generating a low frequency speech signal, and (B) a band processing path high frequencies, made with the possibility of receiving a broadband speech signal and the formation of the speech signal of the high frequency band,! moreover, the speech signal of the low frequency band is based on the first part of the frequency spectrum of the broadband signal, while the first part includes the part of the broadband signal between 1000 and 2000 Hz, a! the highband speech signal is based on the second part of the frequency spectrum of the broadband signal, the second part including the part of the broadband signal between 5000 and 6000 Hz, and! wherein each of the low-frequency band speech signal and the high-frequency band speech signal is based on a third part of the frequency spectrum of the broadband signal, the third part including a part of the broadband signal between 2000 and 5000 Hz, which has a width of at least 250 Hz. ! 2. The device according to claim 1, in which the first part of the broadband signal includes part of the broadband signal between 1000 and 3000 Hz, and the second part of the broadband signal includes part of the broadband signal between 4000 and 6000 Hz, and the third part of the broadband signal including
