摘要： A Universal Serial Bus (USB) system is disclosed. The USB system includes a first host controller. A hub is coupled to the first host controller. A second host controller interfaces with the hub as a USB device. In one embodiment of the USB system, the second host controller is a wireless host controller. The second host controller includes a wireless system side module coupled to the hub and a wireless remote module containing host controller circuitry that receives signals from the wireless system side module. A method for interfacing a hub to a USB system is disclosed. A hub is coupled to a first host controller. The first host controller is coupled to a second hub connected to a second host controller that resides inside the computer.

摘要： A speech system includes a speech encoding system and a speech decoding system. The speech encoding system includes a speech analyzer for identifying each of the speech segments (i.e., phonemes) in the received digitized speech signal. A pitch detector, a duration detector, and an amplitude detector are each coupled to the memory and the analyzer and detect various prosodic parameters of each received speech segment. A speech encoder generates a data signal that includes the speech segment IDs and the values of the corresponding prosodic parameters. The speech decoding system includes a digital data decoder and a speech synthesizer for generating a speech signal based on the segment IDs and prosodic parameter values.

摘要： A speech encoding system for encoding a digitized speech signal into a standard digital format, such as MIDI. The MIDI speech encoding system includes a memory storing a dictionary comprising a digitized pattern and a corresponding segment ID for each of a plurality of speech segments (i.e., phonemes). A speech analyzer identifies each of the segments in the digitized speech signal based on the dictionary. One or more prosodic parameter detectors measure values of the prosodic parameters of each received digitized speech segment. A MIDI speech encoder converts the segment IDs and the corresponding measured prosodic parameter values into a MIDI speech signal. A MIDI speech decoding system includes a MIDI data decoder and a speech synthesizer for converting the MIDI speech signal to a digitized speech signal.
