    Abstract: The subject matter of this specification can be implemented in, among other things, a computer-implemented method for correcting words in transcribed text including receiving speech audio data from a microphone. The method further includes sending the speech audio data to a transcription system. The method further includes receiving a word lattice transcribed from the speech audio data by the transcription system. The method further includes presenting one or more transcribed words from the word lattice. The method further includes receiving a user selection of at least one of the presented transcribed words. The method further includes presenting one or more alternate words from the word lattice for the selected transcribed word. The method further includes receiving a user selection of at least one of the alternate words. The method further includes replacing the selected transcribed word in the presented transcribed words with the selected alternate word.

    Abstract: A method for estimating speech signal in the presence of non-stationary noise includes determining a plurality of initial speech estimates by subtracting a plurality of noise spectra, respectively, from an observed spectrum. Each of the noise spectra is represented by a noise component vector obtained from a Gaussian mixture model. The method also includes determining a plurality of initial noise estimates by subtracting a plurality of speech spectra, respectively, from the observed spectrum. Each of the speech spectra is represented by a speech component vector obtained from another Gaussian mixture model. A plurality of scores is determined, each score corresponding to one of the plurality of initial speech estimates, and calculated from a joint distribution defined by a combination of one of the noise component vectors and one of the speech component vectors. A clean speech estimate is determined as a combination of a subset of the scores.

    Abstract translation: 用于在存在非平稳噪声的情况下估计语音信号的方法包括通过从观测频谱中分别减去多个噪声谱来确定多个初始语音估计。 每个噪声频谱由从高斯混合模型获得的噪声分量矢量表示。 该方法还包括通过从观察到的频谱中分别减去多个语音频谱来确定多个初始噪声估计。 每个语音频谱由从另一个高斯混合模型获得的语音分量向量表示。 确定多个分数，每个分数对应于多个初始语音估计中的一个，并且根据由噪声分量矢量中的一个和语音分量矢量之一组合定义的联合分布来计算。 干净的语音估计被确定为分数子集的组合。
