    • A conferencing device is described which includes at least one speaker, at least one microphone for capturing energy corresponding to near-end speech, a signal interface for connecting to a voice communication system, and a digital signal processor. The digital signal processor is operable to process near-end signals corresponding to the near-end speech energy in each of a plurality of frequency bands to improve intelligibility thereof, and transmit the processed near-end signals to the voice communication system via the signal interface. The digital signal processor is also operable to receive far-end signals from the voice communication system via the signal interface, process the far-end signals in each of the plurality of frequency bands, and transmit the processed far-end signals for presentation over the speaker.
    • 描述了一种会议装置,其包括至少一个扬声器,用于捕获与近端语音相对应的能量的至少一个麦克风,用于连接到语音通信系统的信号接口和数字信号处理器。 数字信号处理器可操作以处理与多个频带中的每个频带中的近端语音能量相对应的近端信号,以提高其可懂度,并且经由信号接口将经处理的近端信号发送到语音通信系统 。 数字信号处理器还可操作以经由信号接口从语音通信系统接收远端信号,处理多个频带中的每个频带中的远端信号,并发送经处理的远端信号以呈现在 扬声器。

    • A conferencing system is described which includes a plurality of conferencing devices and a hub device. Each conferencing device is operable to process near-end speech energy signals to improve the intelligibility of the near-end speech, transmit the processed near-end signals to the hub device, receive far-end signals from the hub device, process the far-end signals, and present the processed far-end signals over its speaker. The hub device is operable to communicate with each of the conferencing devices and a voice communication system, selectively combine the processed near-end signals received from the conferencing devices, transmit the combined near-end signals to the voice communication system, receive the far-end signals from the voice communication system, and transmit the far-end signals to the conferencing devices.
    • 描述了包括多个会议设备和集线器设备的会议系统。 每个会议设备可操作以处理近端语音能量信号以提高近端语音的可懂度,将经处理的近端信号发送到中枢设备,从中枢设备接收远端信号, 结束信号,并通过其扬声器呈现处理的远端信号。 集线器设备可操作以与每个会议设备和语音通信系统通信,选择性地组合从会议设备接收的经处理的近端信号,将组合的近端信号发送到语音通信系统, 来自语音通信系统的终端信号,并将远端信号发送到会议设备。
