Abstract

An electronic device for coding a transient frame is described. The electronic device includes a processor and executable instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a current transient frame. The electronic device also obtains a residual signal based on the current transient frame. Additionally, the electronic device determines a set of peak locations based on the residual signal. The electronic device further determines whether to use a first coding mode or a second coding mode for coding the current transient frame based on at least the set of peak locations. The electronic device also synthesizes an excitation based on the first coding mode if the first coding mode is determined. The electronic device also synthesizes an excitation based on the second coding mode if the second coding mode is determined.

Description

[0001] Claim of priority under 35 U.S.C. §119 [0002] This application claims priority to Provisional Patent Application No. 61 / 382,460, filed September 13, 2010, entitled CODING A TRANSIENT SPEECH FRAME, and assigned to The assignee is hereby expressly incorporated herein by reference. technical field [0003] The present invention generally relates to signal processing. More specifically, the present invention relates to coding and decoding a temporal frame. Background technique [0004] Over the past few decades, the use of electronic devices has become commonplace. In particular, advances in electronic technology have reduced the cost of increasingly complex and useful electronic devices. Cost reductions and consumer demands have proliferated the use of electronic devices to the point that electronic devices are virtually ubiquitous in modern society. As the use of electronic devices expands, so does the demand for new and improved features of electronic devices. ...
