Abstract
A method for determining an interpolation factor set by an electronic device is described. The method includes determining a value based on a current frame property and a previous frame property. The method also includes determining whether the value is outside of a range. The method further includes determining an interpolation factor set based on the value and a prediction mode indicator if the value is outside of the range. The method additionally includes synthesizing a speech signal.
Claims50
A method for determining an interpolation factor set by an electronic device, comprising:
- determining a value based on a current frame property and a previous frame property;
- determining whether the value is outside of a range;
- determining an interpolation factor set based on the value and a prediction mode indicator if the value is outside of the range;
- and
- synthesizing a speech signal.
An electronic device for determining an interpolation factor set, comprising:
- value determination circuitry that determines a value based on a current frame property and a previous frame property;
- interpolation factor set determination circuitry coupled to the value determination circuitry, wherein the interpolation factor set determination circuitry determines whether the value is outside of a range, and determines an interpolation factor set based on the value and a prediction mode indicator if the value is outside of the range;
- and
- synthesis filter circuitry that synthesizes a speech signal.
A computer-program product for determining an interpolation factor set, comprising a non-transitory tangible computer-readable medium having instructions thereon, the instructions comprising:
- code for causing an electronic device to determine a value based on a current frame property and a previous frame property;
- code for causing the electronic device to determine whether the value is outside of a range;
- code for causing the electronic device to determine an interpolation factor set based on the value and a prediction mode indicator if the value is outside of the range;
- and
- code for causing the electronic device to synthesize a speech signal.
An apparatus for determining an interpolation factor set, comprising:
- means for determining a value based on a current frame property and a previous frame property;
- means for determining whether the value is outside of a range;
- means for determining an interpolation factor set based on the value and a prediction mode indicator if the value is outside of the range;
- and
- means for synthesizing a speech signal.
