  • Patent number: 11031029
    Abstract: A pitch detection method. Such a pitch detection method may have M-PWVT-TEO algorithm to detect a pitch value from a speech signal, apply a partial auto-correlation to a current signal with the pitch value to compensate the delay of the pitch value. Also, the pitch detection method may apply a full auto-correlation to the speech signal where the pitch value is not detected to recover on-sets of the speech signal.

  • Patent number: 10854220
    Abstract: A pitch detection method. Such a pitch detection method may use a Teager Energy Operator (TEO) with a Pseudo Weigner Ville Transformation (PWVT) to recover speech from noise and to recover low-frequency information of the speech signal in its detection of a pitch value. Also, the pitch detection method may use the combinatory PWVT and the respective state machine for decision making.

  • Patent number: 10510363
    Abstract: A pitch detection method. Such a pitch detection method may apply Pseudo Weigner Ville Transformation (PWVT) as a spectral representation of speech signal. Also, the pitch detection method may take the median value of each frame of the speech signal as a threshold for making the voicing decision. Additionally, the pitch detection method may take a moving average of PWVT as the threshold for voicing decision.
