Speech enhancement apparatus and method for emphasizing consonant portion to improve articulation of audio signal
In a speech enhancement apparatus, a generator part generates a value representing likelihood of a consonant from an input audio signal, and a calculator part generates a consonant/vowel discriminating signal for discriminating a consonant portion and a vowel portion based on the generated value, detects a first signal level of the vowel portion and a second signal level of the consonant portion based on the audio signal and the consonant/vowel discriminating signal, and outputs a level-related signal. A determining part determines a gain coefficient that exceeds one when the second signal level is smaller than the first signal level based on the level-related signal so that the gain coefficient increases as the second signal level becomes smaller than the first signal level.

Driving force distribution control apparatus for four-wheel drive vehicle and driving force distribution control method for four-wheel drive vehicle
A driving force distribution control apparatus for a four-wheel drive vehicle includes a theoretical value calculator, a normative value calculator, and a servo controller. The theoretical value calculator is configured to calculate a primary rotational speed theoretical value of primary drive wheels and a secondary rotational speed theoretical value of secondary drive wheels based on a steering angle, a vehicle speed, a yaw rate, and a slip angle of the four-wheel drive vehicle and configured to calculate a rotational difference normative theoretical value indicating a difference between rotational speed theoretical values of input and output shafts of a drive force distribution apparatus using the primary rotational speed theoretical value and the secondary rotational speed theoretical value..

Travel control apparatus for four-wheel drive vehicle and travel control method for four-wheel drive vehicle
A travel control apparatus for a four-wheel drive vehicle includes a throttle controller, a driving force distributor, a four-wheel drive controller, a vehicle stability assist controller, a requested target drive torque calculator, and an estimated drive torque calculator. In a case where a failure detector detects a failure and the four-wheel drive controller changes a drive control from a four-wheel drive control to a two-wheel drive control, the travel control apparatus sends a first throttle control signal to the throttle controller and changes the drive control from the four-wheel drive control to the two-wheel drive control when an estimated drive torque is greater than an requested target drive torque, and the travel control apparatus changes the drive control from the four-wheel drive control to the two-wheel drive control without sending the first throttle control signal when the estimated drive torque is not greater than the requested target drive torque..
