  • Patent number: 8892434
    Abstract: There is provided a voice emphasis device with which voice clarity can be improved. This voice emphasis device comprises a correlation component removal filter circuit that removes a correlation component from a voice signal produced at a specific sampling frequency, a multiplication circuit that produces an extracted signal by multiplying a specific gain coefficient by the output of the correlation component removal filter circuit, and an arithmetic circuit that adds or subtracts the extracted signal to or from the voice signal. The correlation component removal filter circuit is a lattice-type filter circuit that combines a feedforward filter and a feedback filter. The feedforward filter and the feedback filter update the filter coefficient at the specific sampling frequency based on the formula ki,j+1=ki,j+?×fi/bi?l.

  • Publication number: 20140297273
    Abstract: 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. A multiplier part multiplies the audio signal by the gain coefficient to output an audio signal having an emphasized consonant portion.
