Abstract: A method and apparatus (400) process a composite signal (202) comprising a spread spectrum signal and an interfering signal (204) to determine the center frequency of the interfering signal, and to shift the composite signal by an amount determined from the characteristic frequency of the interfering signal, thereby creating a shifted composite signal (146) in which the frequency of the interfering signal is a predetermined frequency. The method and apparatus then filters the shifted composite signal to remove the interfering signal, thereby creating an interference-free shifted signal (148), and reshifts the interference-free shifted signal by the amount determined from the characteristic frequency of the interfering signal, thereby recovering the desired spread spectrum signal.

Abstract: A codebook excited linear prediction coding system providing improved digital speech coding for high quality speech at low bit rates with side-by-side codebooks for segments of the modeled input signal to reduce the complexity of the codebook search. A linear predictive filter responsive to an input signal desired to be modeled is used for identifying a basis vector from a first codebook over predetermined intervals as a subset of the input signal. A long term predictor and a vector quantizer provide synthetic excitation of modeled waveform signal components corresponding to the input signal desired to be modeled from side-by-side codebooks by providing codevectors with concatenated signals identified from the basis vector over the predetermined intervals with respect to the side-by-side codebooks. Once a codevector is identified, the codebook at the next segment is searched and a concatenation of codevectors is provided by selecting up to but not including the current segment. The codevector is treated as an additional basis vector for the codebook search at the current segment. It is possible to significantly reduce the complexity of the VSELP codebook search by precomputing and storing the terms for the code search that do not change from segment to segment. Using these techniques, the complexity of searching a 45 bit VSELP codebook (Nnull40, Mnull45, Mnullnull9, Jnull5) was found to be approximately equivalent to searching a traditionally structured 10 bit VSELP codebook (Nnull40, Mnull10, Jnull1). A concatenation of codevectors or carry-along basis vectors are formed as a concatenation of VSELP codevectors selected up to but not including the current segment.

Abstract: In a speech recognition platform, a masking unit 17 can be utilized to mask noisy content within an audio sample. By masking such noise in a dynamic but predictable manner, valid content can be preserved while largely overcoming the random and detrimental presence of noise. In one embodiment, speech recognition features are extracted pursuant to a hierarchical process that localizes, at least to some extent, some of the resultant features from other resultant features. As a result, noisy or otherwise unreliable information corresponding to the audio sample will not be leveraged unduly across the entire feature set. In another embodiment, an average energy value for processed samples is calculated with individual energy values that are downwardly weighted when such individual energy values are likely representative of noise.

Abstract translation: 在语音识别平台中，可以使用掩蔽单元17来掩盖音频样本内的噪声内容。 通过以动态但可预测的方式掩蔽这种噪声，可以保持有效的内容，同时在很大程度上克服噪声的随机和有害存在。 在一个实施例中，语音识别特征是根据分级过程来提取的，该层级过程至少在一定程度上将其它结果特征中的一些特征定位。 因此，与音频样本相对应的噪声或其他不可靠信息将不会在整个特征集中过度使用。 在另一个实施例中，当单个能量值可能代表噪声时，用各个能量值计算处理样本的平均能量值。
