Abstract

본 발명은 CDMA 이동단말기에 키패드를 손으로 직접 눌러서 송신번호를 입력할 필요없이 음성에 의하여 전화번호를 송신하는 방법 및 그 장치에 관한 것이다.The present invention relates to a method and apparatus for transmitting a telephone number by voice without the need to directly enter a transmission number by directly pressing a keypad on a CDMA mobile terminal.

본 발명은 하드웨어 측면에서는 이동단말기에 단순한 음성인식 스위치를 두어 사용하기에 용이한 사용자 인터페이스를 제공한다는 점. A/D 및 D/A 변환기와 음성인식 경로 스위치만 기존 회로에 첨가하면 용이하게 음성인식 하드웨어를 구성할 수 있다는점. 및 기존의 이동단말기에 음성인식 스위치의 개폐여부에 따라 회로의 경로 선택스위치가 변경되어 간단히 음성인식 모드로 절체된다는 점을 특징으로 하며 소프트웨어 측면에서는 단지 10개의 인식단어군만 음성인식하면 되기 때문에 음성인식에 관계된 소프트웨어 분량이 적다는 점, 및 기존의 이동국 소프트웨어에 음성인식 테스크와 관련된 회로에 대한 인터럽트 처리 서비스만 추가하면 쉽게 구현할 수 있다는 점이다.The present invention provides a user interface that is easy to use by having a simple voice recognition switch in a mobile terminal in terms of hardware. Simply adding A / D and D / A converters and voice recognition path switches to existing circuits makes it easy to configure voice recognition hardware. And the path selection switch of the circuit is simply switched to the voice recognition mode according to whether the voice recognition switch is opened or closed in the existing mobile terminal. In terms of software, only 10 recognition word groups need to be recognized. The amount of software involved in the recognition is small, and the existing mobile station software can be easily implemented by simply adding an interrupt processing service for a circuit related to a voice recognition task.
