Problems solved by technology

However, this method will cut off part of the voice segment together with the surge for the situation where there is voice input at the moment when the microphone is turned on, and still cause the back-end voice recognizer to misjudge the incomplete voice signal
[0006] This shows that above-mentioned existing method for eliminating recording surge and device thereof obviously still have inconvenience and defect in method, product structure and use, and urgently need to be further improved
In order to solve the problems of the method and device for eliminating the recording surge, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable general method and device. The method and structure can solve the above-mentioned problems, which is obviously a problem that the relevant industry is eager to solve

Abstract

The invention is relates to an eliminating record dash wave method and its device. The method is applied in electron equipment which possesses a microphone which records voice to generate a voice signal, a segment of signal with dash wave is get and compensated by a preset compensation signal to eliminate the dash wave, the signal segment which is after compensation and the leaving segment are combined to form a whole voice signal. The device includes: a signal intercepting unit, a magnifying unit, a compensation unit and a combining unit to combine the signal segment which is after compensation and the leaving segment to form a whole voice signal. So, the facticity and integrality of voice signal can be maintained to improve the recognizing accuracy ratio.

Description

technical field [0001] The present invention relates to a method and device for eliminating recording surges, in particular to a method and device for eliminating recording surges that are generated on voice signals recorded by electronic equipment at the beginning of recording. Background technique [0002] With the continuous evolution and improvement of mobile (ie, mobile, hereinafter referred to as mobile) computing technology, it has become an important application trend to add the voice recognition function to portable electronic devices such as PDAs and mobile phones. [0003] see figure 1 Shown is a schematic block diagram of an internal circuit of an existing conventional electronic device with a speech recognition function. The existing portable electronic device (such as PDA, mobile navigator or mobile phone, etc.) 1 with voice recognition function in the past will directly send the voice signal (such as a voice command) recorded by its microphone 10 to a voice r...
