[0025] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0026] Figure 1 A flow chart of a cloud XR voice interaction method according to an embodiment of the present disclosure is shown. The method is applied to the XR server, such as Figure 1 As shown, the method includes:

[0027] In step S11, the original input audio sent by the XR client is received.

[0028] The cloud XR voice interaction system includes: XR server and XR client.

[0029] In one example, the XR server is the core part of the cloud XR voice interaction system, which is mainly responsible for data processing and data transmission. The XR server is deployed on the server.

[0030] In one example, the XR client provides an interface for direct interaction with the user, is responsible for displaying virtual content in the interface, and performs voice interaction with the user. The XR client is deployed in the user's head-mounted electronic display device (e.g., a VR helmet).

[0031] In the related art, XR applications (for example, XR conferences, XR digital humans, etc.) run on the XR client. However, due to the limited processor capabilities of the head-mounted electronic display device, the power consumption of the head-mounted electronic display device is relatively high.

[0032] In the disclosed embodiment, the target XR application that requires voice interaction is run on the XR server, and the user can start the XR server and further start the target XR application based on the XR client on the head-mounted electronic display device.

[0033] GStreamer is an open source multimedia framework for creating various complex audio and video processing pipelines. It provides a rich set of APIs that allow developers to easily implement audio and video capture, encoding, decoding, processing, and playback. In the cloud XR voice interaction system, the XR client is generally an Android operating system, and the XR server is generally a Windows or Linux operating system. GStreamer has cross-platform features and can run on multiple operating systems. Therefore, cross-platform voice interaction between XR clients and XR servers can be implemented based on GStreamer.

[0034] After the XR server is started, it detects the connection of the XR client. After receiving the posture data sent by the XR client, the XR server obtains the image and audio data of the currently running target XR application based on the posture data, and encodes the obtained image and audio data and transmits it to the XR client (for example, via the network or USB cable).

[0035] In one example, a hardware speaker is deployed on the head-mounted electronic display device. After the XR client receives the image and audio data, it decodes the image and draws it on the display screen of the head-mounted electronic display device, and decodes the audio data and plays it through the hardware speaker. Compared with the related art of running the target XR application on the XR client, which requires executing a large number of graphics drawing instructions on the XR client, the embodiment of the present disclosure only needs to draw two images of the left and right eyes on the XR client, which can greatly reduce the work of the graphics processor corresponding to the XR client and reduce power consumption.

[0036] The embodiments of the present disclosure focus on the voice interaction process between the XR client and the XR server in the cloud XR voice interaction system. Figure 2 A block diagram of a cloud XR voice interaction system according to an embodiment of the present disclosure is shown. Figure 2 As shown, the cloud XR voice interaction system includes: XR client and XR server.

[0037] In one example, after the XR server is started, the GStreamer integrated in the XR server creates an audio capture pipeline. Based on the audio capture pipeline, the audio data of the target XR application is obtained, and then the audio data of the target XR application is sent to the XR client. Figure 2 As shown, the XR server obtains audio data based on the audio capture pipeline, and encodes the audio data and sends it to the XR client.

[0038] In one example, after the XR client is started, the GStreamer integrated in the XR client creates and starts the audio capture pipeline and the playback pipeline. Figure 2 A block diagram of a cloud XR voice interaction system according to an embodiment of the present disclosure is shown. Figure 2As shown in FIG. 1 , after the XR client is started, the audio capture pipeline and the audio playback pipeline are further started.

[0039] In one example, a hardware speaker is deployed on the head-mounted electronic display device. Based on the audio playback pipeline, the XR client receives the audio data of the target XR application sent by the XR server, and then plays the audio data using the hardware speaker. Figure 2 As shown, the XR client receives the audio data sent by the XR server based on the audio playback pipeline, and plays the audio data.

[0040] In one example, a hardware microphone is deployed on the head-mounted electronic display device, and the hardware microphone can obtain the original input audio of the target user using the head-mounted electronic display device.

[0041] The XR client obtains the original input audio of the target user based on the hardware microphone input, and sends the original input audio to the XR server.

[0042] In the audio capture pipeline of the XR client, the openslessrc plug-in in GStreamer is used to obtain the original input audio of the hardware microphone. Then, the original input audio is encoded based on the appsink plug-in in GStreamer and sent to the XR server. Figure 2 As shown, the XR client obtains the original input audio based on the audio capture pipeline, and sends the original input audio to the XR server.

[0043] In step S12, the target input audio is written to the virtual audio driver deployed in the XR server according to the original input audio.

[0044] A virtual audio driver is deployed in the XR server. The virtual audio driver is used to implement voice interaction between the XR client and the target XR application running in the XR server based on virtual audio technology.

[0045] After receiving the original input audio sent by the XR client, the XR server writes the target input audio to the virtual audio driver deployed in the XR server. The target input audio is obtained based on the original input audio.

[0046] The specific process of how to write the target input audio to the virtual audio driver deployed in the XR server based on the initial input audio will be described in detail later in combination with possible implementation methods of the present disclosure, which will not be repeated here.

[0047] In step S13, the target input audio is read from the virtual audio driver, and the target input audio is sent to the target XR application running in the XR server.

[0048] Based on the virtual audio driver, the target input audio is sent to the target XR application running in the XR server to achieve voice interaction between the XR client and the target XR application.

[0049] The following text will describe in detail how to read the target input audio from the virtual audio driver and send the target input audio to the target XR application running in the XR server in combination with possible implementation methods of the present disclosure, which will not be repeated here.

[0050] In the disclosed embodiment, a high-power target XR application for voice interaction is run on the XR server of the cloud XR system. The XR server receives the original input audio sent by the XR client, and writes the target input audio to the virtual audio driver deployed in the XR server based on the original input audio, so that the target input audio can be read from the virtual audio driver, and the target input audio is sent to the target XR application. Since the target XR application runs on the XR server, the XR client can be lightweight, and the virtual audio technology can be used to effectively realize the voice interaction between the XR server and the XR client.

[0051] In one example, after the virtual audio driver of the XR server is started, a virtual speaker and a virtual microphone device are created, where the virtual speaker is used as an audio rendering device and the virtual microphone is used as an audio capture device.

[0052] In one example, after the XR server is started, the audio write thread is started, and then an audio write pipeline is created in the thread based on GStreamer. Add the GStreamer appsrc component as the data source in the audio write pipeline, set the data input function callback of the data source to provide data (target input audio) for the data source; add audioconvert, audioresample and other audio conversion and decoding components in the audio write pipeline; finally, add the output target component (for example, wasapi2sink on Windows), obtain the device ID of the virtual speaker based on the GStreamer device monitor, and set the device ID of the virtual speaker as the output device of the output target component. Using the audio write pipeline, audio data can be written to the virtual audio driver through the virtual speaker. For example Figure 2 As shown, the XR server obtains the device ID of the virtual speaker, and then creates and opens an audio write pipeline based on the device ID of the virtual speaker.

[0053] In a possible implementation, target input audio is written to a virtual audio driver deployed in an XR server according to original input audio, including: performing audio processing on the original input audio to obtain target input audio; and writing the target input audio to the virtual audio driver.

[0054] After the XR server receives the original input audio sent by the XR client based on the audio write pipeline, it first performs audio processing on the original input audio to obtain the target input audio. The specific processing operation of the audio processing can be based on user configuration or the default setting of the XR server, for example, including: background denoising, adding background music, voice changing, translation, etc., which is not specifically limited in this disclosure. Figure 2 As shown, the XR server receives the original input audio sent by the XR server, and then processes the original input audio to obtain the target input audio.

[0055] In one example, an audio processing module is set in the XR server. After the XR server receives the original input audio sent by the XR client based on the audio write pipeline, it first sends the original input audio to the audio processing module, and then uses the audio processing module to perform audio processing on the original input audio to obtain the target input audio. The specific form of the audio processing module can be flexibly set according to the actual usage, and this disclosure does not make specific limitations on this.

[0056] Compared with the prior art that requires audio processing of the original input audio on the XR client, the embodiments of the present disclosure transfer the audio processing operation to the XR server for execution, which can effectively realize the lightweight of the XR client.

[0057] After the original input audio is processed to obtain the target input audio, the target input audio can be written to the virtual audio driver based on the audio writing pipeline.

[0058] In one possible implementation, the virtual audio driver includes: a virtual speaker; writing the target input audio to the virtual audio driver includes: using a direct memory access (Data Memory Access, DMA) transmission method to read the target input audio from a DMA cache; based on the device ID of the virtual speaker, writing the target input audio to the virtual speaker.

[0059] After the original input audio is processed as above and the target input audio is obtained, the target input audio can be sent to the DMA cache for caching. Then, when the audio write pipeline writes data to the virtual audio driver, the target input audio can be read from the DMA cache and then written to the virtual speaker based on the device ID of the virtual speaker. Figure 2 As shown, the target input audio is written to the virtual speaker.

[0060] In a possible implementation, the virtual audio driver includes: a ring buffer; the method further includes: based on the virtual speaker, sending the target input audio to the ring buffer for storage.

[0061] In order to ensure the continuity and consistency of the audio data, after the target input audio is written to the virtual speaker, the target input audio can be further sent to a ring buffer in the virtual driver audio for storage.

[0062] In one possible implementation, the virtual audio driver includes: a virtual microphone; reading target input audio from the virtual audio driver, and sending the target input audio to the target XR application running in the XR server, including: based on the virtual microphone, reading the target input audio from the ring buffer, and writing the target input audio to the DMA cache; based on the target application program interface API, transmitting the target input audio from the DMA cache to the target XR application.

[0063] When the target XR application reads data from the virtual audio driver, first, based on the virtual microphone, the target input audio is read from the ring buffer, and then the target input audio is written to the DMA cache. At this point, the target XR application can read the target input audio from the DMA cache based on the target API. At this point, the audio input of the XR client is effectively transmitted to the target XR running in the XR server, realizing voice interaction between the XR client and the XR server. Figure 2 As shown, the target XR application reads the target input audio from the virtual microphone.

[0064] In a possible implementation, the method further includes: acquiring target output audio output by the target XR application; and sending the target output audio to the XR client, so that the XR client plays the target output audio.

[0065] The XR server can obtain the target output audio output by the target XR application based on the audio capture pipeline. The target output audio can be the response audio data of the target XR application based on the target input audio, or it can be the response audio data of the target XR application based on the posture data sent by the XR client, which is not specifically limited in this disclosure.

[0066] In the disclosed embodiment, a high-power target XR application for voice interaction is run on the XR server of the cloud XR system. The XR server receives the original input audio sent by the XR client, and writes the target input audio to the virtual audio driver deployed in the XR server based on the original input audio, so that the target input audio can be read from the virtual audio driver, and the target input audio is sent to the target XR application. Since the target XR application runs on the XR server, the XR client can be lightweight, and the virtual audio technology can be used to effectively realize the voice interaction between the XR server and the XR client.
