Abstract: In a method for tracking pitch in a speech signal, first and second window vectors are created from samples taken across first and second windows of the speech signal. The first window is separated from the second window by a test pitch period. The energy of the speech signal in the first window is combined with the correlation between the first window vector and the second window vector to produce a predictable energy factor. The predictable energy factor is then used to determine a pitch score for the test pitch period. Based in part on the pitch score, a portion of the pitch track is identified.

Abstract: PROBLEM TO BE SOLVED: To provide a headlight system for a vehicle for conducting beam control of headlights capable of sufficiently irradiating them in a direction necessary for a driver even when it is getting closer to a curved road as well as during traveling on a curved road, and realizing it in a simple method. SOLUTION: When the vehicle 2 is traveling on a right-curved road B, an angle θ1 for seeing a center line CL in the tangential direction from a specified point M of the vehicle is set as a target irradiation angle of beam control. When the vehicle 2 traveling on a straight road A gets closer to a specified position before a start position P1 of the right-curved road B, an angle θ2 at the start position P1 for seeing a point TP2 on the center line CL is set as the target irradiation angle. The target irradiation angle can thus be easily determined as it is close to the angle in the tangential direction (a watching direction of the driver) to the center line CL on the right-curved road B.  When the vehicle 2 further gets closer to the start position P1 to make the angle θ2 greater than the angle θ1, the angle θ1 is set as the target irradiation angle till the vehicle 2 invades into the right curved road B. When the vehicle 2 most gets closer to the right curved road B, the target irradiation angle can be maintained at a close value to the angle in the tangential direction.
