Embodiment Construction

[0086] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0087] see figure 1 , figure 1 A flow chart of a voice data recognition method provided by an embodiment of the present invention; the method includes:

[0088] Step 101: Acquiring voice data;

[0089] In this step, the desktop cloud client obtains the voice data input by the user through the voice collection system. Usually, the voice data is Pulse Code Modulation (PCM, Pulse Code Modulation) voice data. Wherein, the sound collection system is, for example, a mic...

Abstract

The embodiment of the present invention discloses a voice data recognition method and device, the method comprising: acquiring voice data; identifying the voice data, and if the voice data is recognized as command voice data, determining the command voice The command code corresponding to the data; the command code is sent to the desktop cloud service end through the command control channel, so that the desktop cloud service end determines the corresponding standard voice data according to the command code, and inserts the standard voice data into the to the audio redirection data queue for identification. The embodiment of the present invention solves the technical problem in the prior art that the success rate of speech recognition is reduced when audio lossy codec or real-time transmission protocol is adopted.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a voice data recognition method and device. Background technique [0002] In the existing desktop cloud redirection scenario, in order to ensure the minimum bandwidth consumption and reduce the transmission delay during network transmission, the desktop cloud client usually uses a lossy encoding method for audio data (such as speex, vobis audio encoding method, etc.), that is, lossy compression is performed on the original PCM data, and then the compressed data is transmitted to the desktop cloud server, which is decompressed by the desktop cloud server and restored to PCM data, and the restored PCM data is sent to the audio redirection Driver, in order to complete the corresponding audio operation. [0003] However, in this voice recognition scenario, the success rate of voice command recognition will depend on whether the input PCM audio data is complete and clear. Howe...
