Abstract

The invention discloses a voice feature extraction control device for a recording pen. The control device comprises a microphone, a high frequency amplifier, a converter, a central controller, a memory and a display; the central controller comprises an identification unit, a calculation unit, a comparison unit and an extraction unit; the microphone is used for recording voice signals; the high frequency amplifier amplifies the recorded voice signals; the converter converts the voice signals into digital signals; the identification unit is used for voice identification and obtains voice feature; the storage unit is used for storage; the calculation unit calculates the appearance frequency; the comparison unit compares the appearance frequency to obtain the highest frequency; the extraction unit extracts voice feature of the highest frequency; and the display is used for display. The voice feature extraction control device uses simple structure to detect and identify voice signals, improves the automation degree, and enables functions of the recording pen to be more complete.

Description

technical field [0001] The invention relates to a voice feature extraction control device for a recording pen, belonging to the technical field of recording pen control. Background technique [0002] Digital recorder, also known as digital recording stick or digital recorder, is a kind of digital recorder. In order to facilitate operation and improve recording quality, the shape is not based on a simple pen shape. It is easy to carry and has multiple functions, such as a laser pointer. Function, FM FM, MP3 player, etc. Compared with traditional tape recorders, digital voice recorders record audio through digital storage. [0003] The digital voice recorder will complete the recording, and the input device is indispensable. An input device is a device that a digital voice recorder accepts an externally discernible sound. Such as built-in microphone, external microphone, connection with telephone handset, etc. Although the recording time of the digital voice recorder is lo...
