Embodiment Construction

[0020] see figure 1 As shown, a kind of voice delay test method based on the virtualized desktop environment of the present invention comprises measuring the time delay required for the audio software on the virtualized desktop of the virtual machine to be used in conjunction with the virtualized desktop and measuring the client and the virtualized desktop. Latency of voice application between virtualized desktops:

[0021] The audio software on the virtualized desktop of the measurement virtual machine and the time delay required for the use of the virtualized desktop specifically include:

[0022] Step 1, load a voice signal source file on the virtualized desktop of the virtual machine (this loading can be to copy a voice signal source file or obtain the voice signal source file from external download), use the sound virtual line, the sound of the virtual machine The output end is connected with the sound input end; the digital signal of the sound output end is directly tra...

Abstract

The invention provides a voice time-delay test method based on a virtualization desktop environment. A time-delay T1 required by the match of a voice software on a virtualization desktop of a virtual machine and the virtualization desktop as well as a time-delay T2 used for voice application between a client and the virtualization desktop are measured, and then the time-delay T2 subtracts the time-delay T1, so as to obtain the voice delayed time under the virtualization desktop environment. The test method can measure the voice mapping delayed time between the whole client and a virtualization desktop end. The test method has the characteristics that the test arrangement mode is simple, so that the test method can be realized only in a way that a voice signal is played on the virtualization desktop; moreover, a professional test instrument does not need to be purchased, and therefore, the input cost is saved.

Description

【Technical field】 [0001] The invention relates to a voice delay testing method based on a virtualized desktop environment. 【Background technique】 [0002] VDI, the English full name is Virtual Desktop Infrastructure, that is, virtual desktop infrastructure. Instead of configuring each user with a desktop PC running Windows XP or Vista, it virtualizes your desktop by running Windows XP on a server in the data center; Client Computing Protocol for Home PC) is connected to virtual desktops, and users access their desktops as if they were accessing traditional locally installed desktops. When playing audio signal source files in a virtualized desktop environment, there will be a voice delay. If the delay time is too long, it will not only affect the user's access efficiency, but also reduce the user experience. The following voice delay is tested, and the test time is obtained to determine whether the server or the client device needs to be improved to reduce the voice delay. ...
