Title:
METHOD AND APPARATUS FOR PROCESSING SIGNAL DATA, AND INTELLIGENT CONFERENCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/040431
Kind Code:
A1
Abstract:
Disclosed are a method and an apparatus for processing signal data, and an intelligent conference device. The method comprises: obtaining data length information of signal data of a reference cache region and an input cache region within a current processing period separately; determining, based on the data length information of the reference cache region and the input cache region, data length difference information between the signal data cached in the reference cache region and the input cache region; and determining a result of comparison between the data length difference information and standard data length difference information, and re-sampling signal data stored in the reference cache region and/or the input cache region on the basis of the comparison result. By using the method, a difference between signal data sampling rates of two cache regions during a voice call can be determined easily and effectively. Therefore, it is ensured that a data length difference between the signal data in the reference cache region and the input cache region is a fixed value in real time. Moreover, echo cancellation can be performed simultaneously on the signal data of the two cache regions during a voice call.
