Abnormal voice data processing method and apparatus

Abstract

The invention provides a data processing method of the abnormal audio which is used to process the abnormal audio data at the input terminal of the wireless digital. The method comprises that builds the buffer area, judges if the received audio data is abnormal after receiving the audio data, if the data is not abnormal, puts successively the received audio data to the buffer area according to the predetermined buffer form, otherwise, carries out the replace processing of the audio data according to the buffer form and saves the processed audio data into the buffer area. The invention also provides a processing device of the abnormal audio data which is used to process the abnormal audio data at the input terminal of the wireless digital. The device comprises a buffer area, a judge and control unit. Therefore, the method and the device of the invention has great versatility, can also restore the abnormal audio data based on the product of providing the wireless access and also has traceability and large applicable scope, and simple and feasible application.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more particularly, to a method and device for processing abnormal voice data. Background technique [0002] "Wireless digital access terminal" (hereinafter referred to as access core), also known as wireless modem, is a wireless access device, similar in appearance to an ordinary modem. Using wireless access methods such as CDMA or GSM, within the coverage of the wireless network, you can connect to ordinary phones, answer and make local, domestic and international calls anytime and anywhere; you can also connect to a computer, use the wireless network to browse the web, download content, etc. . CDMA originated in the United States in the 1980s. It uses code division multiple access to distinguish different users. It has developed very rapidly in the United States and South Korea. It also has a very large number of users in my country and has become the third-generatio...

Problems solved by technology

[0006] During a normal call, in addition to the normally sent sound, there will be other sounds, such as the Dual Tone Multiple Frequency (DTMF) tone of the phone button. This sound needs to be correctly recognized by the other party in many cases, but due to This sound is mixed with the sound signal, and after PCM coding and compression coding of the wireless chipset, the voice data has a high bit error, which makes the peer end unable to parse it normally. Voice data known as abnormal
