摘要： [Problem] To provide a technology capable of comfortably enjoying audio content via multiple channels even in a noisy environment. [Solution] A wireless terminal 3 is disposed at a listening point of a multi-channel audio device 1. The multi-channel audio device 1 plays a multi-channel audio signal as audio playback signals of a plurality of channels, and outputs an audio playback signal for each channel from the corresponding speaker 2, and the wireless terminal 3 collects the environmental sound at the listening point, and transmits the sound collection signal to the multi-channel audio device 1. The multi-channel audio device 1 identifies, as a noise component, the difference between the sound collection signal received from the wireless terminal 3 and the audio playback signals of the plurality of channels output from the plurality of speakers, generates a noise canceling signal with the opposite phase to the noise component, and outputs the noise canceling signal from any speaker 2.

摘要： A speech to text system includes a text and labels module receiving a text input and providing a text analysis and a label with a phonetic description of the text. A label buffer receives the label from the text and labels module. A parameter generation module accesses the label from the label buffer and generates a speech generation parameter. A parameter buffer receives the parameter from the parameter generation module. An audio generation module receives the text input, the label, and/or the parameter and generates a plurality of audio samples, A scheduler monitors and schedules the text and label module, the parameter generation module, and/or the audio generation module. The parameter generation module is further configured to initialize a voice identifier with a Voice Style Sheet (VSS) parameter, receive an input indicating a modification to the VSS parameter, and modify the VSS parameter according to the modification.

摘要： [Problem] To provide an audio device having a voice operation receiving function with which the state of a voice recognition process can be notified in detail without affecting an audio playback environment, and which is inexpensive and has an excellent degree of freedom in design. [Solution] A wireless speaker 1 has a voice operation receiving function that receives an operation by a voice input into a microphone 11. The wireless speaker comprises: an LED 12; an LED control unit 18 that subjects the LED 12 to PWM control; and a lighting pattern storage unit 17 that stores a lighting pattern in which the brightness is changed on a time axis for each state of a voice recognition process. The LED control unit 18 subjects the LED 12 to PWM control in accordance with the lighting pattern stored in the lighting pattern storage unit 17 corresponding to the state of the voice recognition process performed on the voice input into the microphone 11.

摘要： Provided is a technology for supporting solution of a fault that has occurred in a system including an audio-visual device. A solution support program storage unit (7) is configured to store, for each potential fault, a solution support program for supporting a user's job for solving the each fault. At least one of the solution support programs for handling a fault having a plurality of possible causes includes processing for displaying a message for prompting the user to conduct a predetermined job, processing for displaying a question for the user, processing for receiving a user's answer to the question, and processing for displaying a message indicating a solution corresponding to the received answer. Then, a main control unit (9) determines a fault based on the information acquired through an audio-visual signal input interface unit (3) and an audio-visual signal output interface unit (4), and executes the solution support program for handling the determined fault.

摘要： A media rendering system includes a media rendering device and a controller device in communication via a network. The controller has a touch screen, presenting a portrait display mode when oriented in a first position, and a landscape display mode when oriented in a second position. The portrait mode displays either a first full screen presenting a first menu, or a second full screen presenting a second menu. The landscape mode displays a landscape full screen with two side-by-side tiles including a first tile presenting the first menu and a second tile presenting the second menu. Landscape mode provides drag-and-drop functionality for menu objects among the first and second, generating configuration commands to the media rendering device.

摘要： Described herein are systems and methods for providing dual control functionality in a networked digital media device. In overview, a networked digital media device advertises a standard digital media device, which is discoverable and controllable by a standard control device in accordance with a standard media control protocol (also referred to as a Device Control Protocol, or DCP). The networked digital media device also advertises a non-standard digital media playback device, the non-standard device being discoverable and controllable by a non-standard control device in accordance with a non-standard media control protocol. These two devices are manifested in the same device hardware, essentially allowing the device to implement dual-control such that it is able to be controlled both as a standard device and a non-standard device.

摘要： Described herein are systems and methods for synchronization in a networked environment. For example, some embodiments provide methods for synchronizing a client device having a client media time reference with a server device having a server media time reference. In some cases such methods are embodied in computer readable code that is executable on one or more processors. Furthermore, some embodiments provide hardware, such as networked media devices that are configured to perform such methods. In overview, in some embodiments a client obtains timing information from a server and, on the basis of this timing information, applies an adjustment to a client control time reference, thereby to synchronize the client media time reference with the server media time reference. Some embodiments are particularly directed to the situation where there is a desire to synchronize networked media devices across a combination of wired and wireless networks.
