Abstract: This disclosure provides a method of decoding a digital speech signal, a speech decoder, a handset or mobile radio, and a base station or console. The method includes receiving a voice bit stream including at least one frame of bits that includes block codes, determining least confident bits in a first block code, generating candidates for the first block code based on the least confident bits, determining a first distance between each candidate and the first block code, and demodulating at least one other block code to obtain at least one demodulated vector. For each demodulated vector, a second distance between the demodulated vector and possible transmitted vectors is determined, and from the possible transmitted vectors, a vector corresponding to a minimum second distance is selected as a corrected demodulated vector. A minimum total distance is determined, and a candidate is selected as a corrected first block code.

Abstract: This disclosure provides a method of correcting errors in a digital speech signal, a speech decoder, a handset or mobile radio, and a base station or console. The method includes receiving a voice bit stream including voicing bits of a current frame, voicing bits of a prior frame, and a voicing confidence measure for the current frame; generating a set of common voicing patterns for the current frame; resampling voicing bands of the prior frame, so that the number of voicing bands in the resampled prior frame is the same as the number of voicing bands in the current frame; determining a distance for each of the set of common voicing patterns with respect to the current frame and the prior frame; and replacing the current frame with a particular voicing pattern in the set of common voicing patterns, wherein the particular voicing pattern has the minimum distance.

Abstract: Tone data embedded in a voice bit stream that includes frames of non-tone bits and frames of tone bits is detected and extracted by selecting a frame of bits, analyzing the selected frame of bits to determine whether it is a frame of tone bits, and, when it is a frame of tone bits, extracting tone data from it. Analyzing the selected frame includes comparing bits of the selected frame to sets of tone data to produce error criteria representative of differences between the selected frame and each of multiple sets of tone data. Based on the error criteria, a set of tone data that most closely corresponds to the bits of the selected frame is selected. When the error criteria corresponding to the selected set of tone data satisfies a set of thresholds, the selected frame is designated as a frame of tone bits.

Abstract: Compensating a speech signal for the presence of a speaker mask includes receiving a speech signal, dividing the speech signal into subframes, generating speech parameters for a subframe, and determining whether the subframe is suitable for use in detecting a mask. If the subframe is suitable for use in detecting a mask, the speech parameters for the subframe are used in determining whether a mask is present. If a mask is present, the speech parameters for the subframe are modified to produce modified speech parameters that compensate for the presence of the mask.
