Description

Text recognition and voice synthesis phone

The present invention is to provide a character recognition and speech synthesis phone to recognize the input character to convert the voice to be transmitted and to transmit and to convert the received voice into a character to visually display.

The present invention relates to a telephone, and more particularly to a telephone capable of text recognition and speech synthesis.

In general, a phone amplifies a voice input into a microphone and delivers the voice to the other party through a telephone line, and the voice transmitted from the other party is output to a speaker so that a call can be made with the other party.

In such a general telephone, both the talker and the talker can speak only by voice, and cannot talk by other functions (text).

Therefore, when using such a general telephone, the person who cannot speak or who cannot hear cannot use the telephone.

In other words, a person who can't speak can hear the other's voice, but because he can't speak, he can't communicate his thoughts to the other, and a person who can't hear can deliver his / her voice to the other. For example, the other party cannot hear the other party's voice.

Now the present invention has been proposed to solve the shortcomings of the general phone as described above, the present invention is to recognize the input characters to convert the voice to be transmitted and to transmit the received voice to the character to display the text visually The object is to provide a recognition and speech synthesis telephone.

Technical means for achieving the object of the present invention, the character input unit for displaying their intentions in writing; A text / voice converter for recognizing a text input through the text input unit and converting the text into a voice; A voice output unit for amplifying the voice converted by the text / voice converter to a predetermined level and outputting the voice line to a telephone line; A voice input unit configured to receive a voice transmitted from the other party; A voice / text converter for converting a voice or tone obtained by the voice input unit into a text fee; It consists of a display unit for visually displaying the characters converted by the speech / text conversion unit.

Hereinafter, with reference to the accompanying drawings of the present invention will be described in more detail.

1 is a block diagram of a text recognition and voice synthesis telephone according to the present invention.

Here, reference numeral 10 is a character input unit for displaying his intentions in writing, 20 is a character / voice conversion unit for recognizing a character input through the character input unit 10 and converting it into a voice, and 30 is the character / It is a voice output unit for amplifying the voice converted by the voice conversion unit 20 to a predetermined level and outputting it to the telephone line.

In addition, reference numeral 40 is a voice input unit for receiving a voice transmitted from the other party, 50 is a voice / text conversion unit for converting the voice or tone obtained from the voice input unit 40 to the text, 60 is the voice / text The display unit visually displays the characters converted by the conversion unit 50.

Reference numeral 70 is a handset comprising a receiver for transmitting the received voice to the outside and a receiver for receiving the voice.

In the above description, the character input unit 10 includes a keyboard 11 for inputting a character, a keyboard controller 12 for recognizing operation keys of the keyboard 11, and a touch panel for inputting characters using a touch pen. 13 and a touch panel driver 14 that recognizes a coordinate point in contact with the touch panel 13 and outputs it as a character.

In addition, the audio output unit 30 may include a digital / analog converter 31 for converting the converted digital voice signal into an analog voice signal, and an amplifier for amplifying the analog voice output from the digital / analog converter 31 to a predetermined level. And a speaker 33 for outputting the sound obtained from the amplifier 32 to the telephone line.

The voice input unit 40 includes a microphone 41 for receiving the other party's voice, an amplifier 42 for amplifying the voice input from the microphone 42 to a predetermined level, and amplified by the amplifier 42. It consists of an analog / digital converter 43 for converting an analog voice signal into a corresponding digital voice signal.

In addition, the display unit 60 is an LCD controller 61 for extracting and outputting the corresponding character from the font ROM 62 in accordance with the character control signal obtained from the voice / text conversion unit 50, and the LCD controller 61 It consists of an LCD (63) for visually displaying the characters obtained from.

Next, the text / voice conversion unit 20 and the voice / text conversion unit 50 convert the input voice or text according to a program stored in the program ROMs 23 and 53 and the text into voice. Each of the digital signal processing units 21 and 51 converts.

The switch according to the present invention having such a configuration is connected to the other party after dialing in a state in which driving power is supplied to each end by the power supply 90, and the keyboard 11 or touch provided in the character input unit 10 is touched. Enter your intention through panel 13. In this case, a signal input through the keyboard 11 is processed by the keyboard controller 12 and transmitted to the character / voice converter 20, and the character input by the touch panel 13 is touched by the touch panel driver 14. Recognized and transmitted to the text / voice conversion unit 20. Then, the text / voice conversion unit 20 searches the operation state of the LED and the switch unit 80 to determine whether the user wants the female voice or the male voice first, and if the female voice is desired, the program ROM 23 The character inputted according to the program stored in the digital female voice data is converted into the voice output unit 30 and is transmitted to the voice output unit 30 (where the male male voice data is outputted if desired). Then, the voice output unit 30 converts the digital voice data input from the digital / analog converter 31 into an analog voice signal, amplifies the amplifier 32 to a predetermined level, and sends the same to the speaker 33. The same as the normal person inputs the voice through the handset 70. Since the voice transmission process is the same as the voice transmission of a general telephone, it will be omitted.

Next, the voice transmitted from the other party is amplified to a predetermined level by the amplifier 42 through the microphone 41 in the voice input unit 40, and then converted into digital voice data by the analog / digital converter 43 to be converted into voice / It is input to the character conversion part 50. Then, the digital signal processing unit 51 in the voice / text conversion unit 50 converts the digital voice data input according to the program stored in the program ROM 53 into text data corresponding thereto, and transmits the same to the display unit 60. , The display unit 60 is the LCD controller 61, the character corresponding to the input character data is extracted from the font ROM 62 and transmitted to the LCD 63 side, the voice transmitted from the counterpart is displayed as a character. .

This makes it possible for people who do not speak or cannot hear you to speak to the other party.

As described above, the present invention converts and transmits the input character to the voice, and the other party's voice is converted to the character and displayed so that the person who can not speak or hear the voice can talk to the other party through the phone. There is.
