    • A system for processing a speech signal to enhance signal intelligibility identifies portions of the speech signal that include sounds that typically present intelligibility problems and modifies those portions in an appropriate manner. First, the speech signal is divided into a plurality of time-based frames. Each of the frames is then analyzed to determine a sound type associated with the frame. Selected frames are then modified based on the sound type associated with the frame or with surrounding frames. For example, the amplitude of frames determined to include unvoiced plosive sounds may be boosted as these sounds are known to be important to intelligibility and are typically harder to hear than other sounds in normal speech. In a similar manner, the amplitudes of frames preceding such unvoiced plosive sounds can be reduced to better accentuate the plosive. Such techniques will make these sounds easier to distinguish upon subsequent playback.
    • 用于处理语音信号以增强信号可懂度的系统识别包括通常呈现可懂度问题的声音的语音信号的部分,并以适当的方式修改那些部分。 首先,语音信号被分成多个基于时间的帧。 然后分析每个帧以确定与该帧相关联的声音类型。 然后基于与帧或与周围帧相关联的声音类型来修改所选择的帧。 例如,确定为包括清音爆破声音的帧的幅度可以被提升,因为已知这些声音对于可懂度是重要的,并且通常比正常语音中的其它声音难以听到。 以类似的方式,可以减少在这种清音爆破声之前的帧的振幅,以更好地强调爆破声。 这样的技术将使得这些声音在随后的播放中更容易区分。

    • The VoIP quality speech process is activated when a subscriber accesses a speech quality sensitive resource or in response to an activation of the feature by the subscriber, or when it is determined that the originating subscriber terminal device requires the transmission of high quality speech signals. A transmit buffer, associated with the port circuit that serves the originating device, stores a predetermined number of packets as they are transmitted from the originating device. In the case of lost or damaged packets, the VoIP quality speech system activates the transmit buffer to retransmit the missing or damaged packet to the destination device. Intelligent buffer management is provided, where the destination device can regulate the size of the transmit buffer as well as the size of its jitter buffer.
    • 当用户访问语音质量敏感资源或响应于订户激活特征时,或者当确定发起用户终端设备需要高质量语音信号的传输时,VoIP质量语音过程被激活。 与起始设备服务的端口电路相关联的发送缓冲器在从始发设备发送时存储预定数量的分组。 在丢失或损坏的数据包的情况下,VoIP质量语音系统激活发送缓冲区以将丢失或损坏的分组重传到目的地设备。 提供了智能缓冲区管理,目标设备可以调节发送缓冲区的大小以及抖动缓冲区的大小。
