Systems and methods for determining an interpolation factor set for synthesizing a speech signal

摘要

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.

1. 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 a determination that the value is outside of the range and a prediction mode indicator; interpolating subframe line spectral frequency (LSF) vectors based on the interpolation factor set to produce interpolated LSF vectors; and synthesizing a speech signal based on the interpolated LSF vectors.
