Problems solved by technology

[0005] It can be seen that this kind of TTY device or TDD used to realize the communication of users who do not have voice ability or / and hearing ability is an external device of the communication terminal, which needs to be purchased separately, which increases the cost of use
In addition, due to its own processing circuit, display screen and speaker / microphone or communication voice output and input interface, it is bulky and inconvenient to carry
Therefore, this communication method for users who do not have speech ability or / and do not have hearing ability is relatively poor for users.

Embodiment Construction

[0039] In order to make the objectives, technical solutions, and advantages of the present invention clearer and more comprehensible, specific embodiments are given below to further describe the present invention in detail with reference to the accompanying drawings.

[0040] The present invention sets the communication voice and character conversion function on the existing communication terminal, that is, sets the corresponding relationship between the communication voice and the character conversion on the communication terminal, so as to realize the communication in the read-write mode. Since the conversion function can be set on the existing hardware of the existing communication terminal by software, it will not increase the hardware cost and the volume of the communication terminal. Compared with the prior art, the TTY device is connected to the communication device to realize the communication in the read-write mode. In comparison, the cost is reduced, the portability is c...

Abstract

The invention discloses a communication terminal adopting a read-write mode and a method for realizing communication in the read-write mode. The communication terminal comprises a modem unit, a converting unit, an input unit and a display unit, wherein the modem unit is used for receiving communication speech from a communication network and demodulating the communication speech to obtain wave form data which is then sent to the converting unit; the wave form data received from the converting unit is demodulated to obtain the communication speech which is then transmitted into the communication network; the converting unit is used for converting the wave form data received from the modem unit into characters which are sent to the display unit; after being converted into the wave form data, the characters which are received from the input unit are sent to the modem unit; the display unit is used for displaying the characters received from the converting unit; and the input unit is used for sending the input characters to the converting unit. The communication terminal and the method can adopt the read-write mode for realizing communication.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a communication terminal adopting a read-write mode and a method for realizing communication in the read-write mode. Background technique [0002] With the development of communication technology, users can communicate through various types of communication terminals, and commonly used communication terminals generally communicate through voice. However, such a communication terminal that communicates by means of voice is not suitable for users who do not have the language ability or / and the hearing ability, resulting in these users being unable to communicate with this communication terminal. [0003] In order to solve this problem, TTY (Tele TypeWriter) equipment or Telecommunication Device for the Deaf (TDD) used by deaf-mute people have appeared at present. TTY equipment or TDD has the function of voice and character conversion. Or TDD connects to a communication terminal that...
