  • Patent number: 6477471
    Abstract: A software predictive engine is described that provides a tool to analyze the import of defects in the software development process. By providing a prediction of escaping defects, in terms of the normalized sigma measure and the predicted lines of code, together with historical data the impact of defects at the stages of the design can be predicted. As actual defects are measured predicted sigma level can also be predicted. The engine includes generating a defect containment matrix for the historical data and for the current software program being developed.

  • Patent number: 6456974
    Abstract: In a system (10) for adding speech recognition capabilities to Java, there is provided a speech recognition server (18) coupled to a Java application (24) through an application program interface (20). The Java application (24) dynamically specifies a grammar (56) to the application program interface (20), which communicates the grammar (56) to the speech recognition server (18). The speech recognition server (18) receives the grammar (56) and a speech input (66). Upon receiving the speech input (66), the speech recognition server (18) performs speech recognition and generates a result (58) based on the grammar (56). The application program interface (20) communicates the result (58) to the Java application (24), which performs an action based on the result (58) received.

  • Patent number: 6456965
    Abstract: A “multi-stage” method of estimating pitch in a speech encoder (FIG. 2). In a first stage of the method, a set of candidate pitch values is selected, such as by using a cost function that operates on said speech signal (steps 21-23). In a second stage of the method, a best candidate is selected. Specifically, in the second stage, pitch values calculated from previous speech segments are used to calculate an average pitch value (step 25). Then, depending on whether the average pitch value is short or long, one of two different analysis-by-synthesis (ABS) processes is then repeated for each candidate, such that for each iteration, a synthesized signal is derived from that pitch candidate and compared to a reference signal to provide an error value. A time domain ABS process is used if the average pitch is short (step 27), whereas a frequency domain ABS process is used if the average pitch is long (step 28).

  • Patent number: 6442277
    Abstract: A method and device for placement of sound sources in three-dimensional space via two loudspeakers. This technique uses an efficient implementation which consists of binaural signal processing and loudspeaker crosstalk cancellation, followed by panning into the left and right loudspeakers. For many applications, the binaural signal processing and crosstalk cancellation can be performed offline and stored in a file. Because, in this situation, panning is the only required operation, this technique results in a low-computation, real-time system for positional 3D audio over loudspeakers.

  • Patent number: 6437808
    Abstract: An apparatus and method for transmitting graphical representations is disclosed. The present invention has an image generator (112) that generates an image (114) of a head (106) with facial features, including an eye portion (202) that correlates to an eye (240) in the head (106). The apparatus also has a non-updating tracker (116) that searches for an eye target image of the eye (240) in the head (106). The eye portion (202) correlating to the eye (240) is positioned at the target image located by the non-updating tracker (116). The apparatus also has an updating tracker (118) that searches for an updated eye target image when the non-updating tracker (116) is unable to locate the eye target image. The updating tracker (118) also positions the eye portion (202) at the updated eye target image and updates the updated eye target image with the eye portion (202). The updating tracker further determines the location of the eye portion (202).
