ABSTRACT:
FIELD OF THE INVENTION
The invention relates to a telephony device comprising at least one digital processing element for processing digital speech signals and a digital type of responder.
The invention also relates to a method implemented in such a device.
The invention finds interesting applications, notably in the field of telephones comprising a digital type of responder, for example, those satisfying the DECT standard. These digital responders are more and more indispensable because of their ease of use combined with their large robustness.
BACKGROUND OF THE INVENTION
In telephony devices of the DECT type which comprise digital processing elements, the responder has to comprise its own converter, so that the data it produces or receives are adapted to the storage of the longest possible messages for a reasonable storage capacity while the criterions of an acceptable intelligibility are complied with.
SUMMARY OF THE INVENTION
The present invention proposes a device of the type defined in the opening paragraph which carries out the function of responder without needing such hardware.
Therefore, such a device is characterized in that it comprises processing control means so that said processing element also processes the speech signals for said responder.
The idea of the invention consists of benefiting from the presence of the converter already used in the device and from making the converter operate so that the requirements regarding the duration and intelligibility of recorded messages in the responder are satisfied by utilizing at least one coding format for the responder.
According to one embodiment, selection means are provided for the user to determine one of the formats with regard to the responder, which leads to the advantage that the user can select either a long recording duration or a better quality of the recorded messages.
According to another embodiment, automatic switching means are provided, so that one part of the message is recorded with a high quality and another part with a low quality.
