  text: In this work, we address the limited availability of large annotated databases
    for real-life audio event detection by utilizing the concept of transfer learning.
    This technique aims to transfer knowledge from a source domain to a target domain,
    even if source and target have different feature distributions and label sets.
    We hypothesize that all acoustic events share the same inventory of basic acoustic
    building blocks and differ only in the temporal order of these acoustic units.
    We then construct a deep neural network with convolutional layers for extracting
    the acoustic units and a recurrent layer for capturing the temporal order. Under
    the above hypothesis, transfer learning from a source to a target domain with
    a different acoustic event inventory is realized by transferring the convolutional
    layers from the source to the target domain. The recurrent layer is, however,
    learnt directly from the target domain. Experiments on the transfer from a synthetic
    source database to the reallife target database of DCASE 2016 demonstrate that
    transfer learning leads to improved detection performance on average. However,
    the successful transfer to detect events which are very different from what was
    seen in the source domain, could not be verified.

  text: This report describes the computation of gradients by algorithmic differentiation
    for statistically optimum beamforming operations. Especially the derivation of
    complex-valued functions is a key component of this approach. Therefore the real-valued
    algorithmic differentiation is extended via the complex-valued chain rule. In
    addition to the basic mathematic operations the derivative of the eigenvalue problem
    with complex-valued eigenvectors is one of the key results of this report. The
    potential of this approach is shown with experimental results on the CHiME-3 challenge
    database. There, the beamforming task is used as a front-end for an ASR system.
    With the developed derivatives a joint optimization of a speech enhancement and
    speech recognition system w.r.t. the recognition optimization criterion is possible.

  text: In this paper we show how a neural network for spectral mask estimation for
    an acoustic beamformer can be optimized by algorithmic differentiation. Using
    the beamformer output SNR as the objective function to maximize, the gradient
    is propagated through the beamformer all the way to the neural network which provides
    the clean speech and noise masks from which the beamformer coefficients are estimated
    by eigenvalue decomposition. A key theoretical result is the derivative of an
    eigenvalue problem involving complex-valued eigenvectors. Experimental results
    on the CHiME-3 challenge database demonstrate the effectiveness of the approach.
    The tools developed in this paper are a key component for an end-to-end optimization
    of speech enhancement and speech recognition.

  text: The benefits of both a logarithmic spectral amplitude (LSA) estimation and
    a modeling in a generalized spectral domain (where short-time amplitudes are raised
    to a generalized power exponent, not restricted to magnitude or power spectrum)
    are combined in this contribution to achieve a better tradeoff between speech
    quality and noise suppression in single-channel speech enhancement. A novel gain
    function is derived to enhance the logarithmic generalized spectral amplitudes
    of noisy speech. Experiments on the CHiME-3 dataset show that it outperforms the
    famous minimum mean squared error (MMSE) LSA gain function of Ephraim and Malah
    in terms of noise suppression by 1.4 dB, while the good speech quality of the
    MMSE-LSA estimator is maintained.

  text: Recent advances in discriminatively trained mask estimation networks to extract
    a single source utilizing beamforming techniques demonstrate, that the integration
    of statistical models and deep neural networks (DNNs) are a promising approach
    for robust automatic speech recognition (ASR) applications. In this contribution
    we demonstrate how discriminatively trained embeddings on spectral features can
    be tightly integrated into statistical model-based source separation to separate
    and transcribe overlapping speech. Good generalization to unseen spatial configurations
    is achieved by estimating a statistical model at test time, while still leveraging
    discriminative training of deep clustering embeddings on a separate training set.
    We formulate an expectation maximization (EM) algorithm which jointly estimates
    a model for deep clustering embeddings and complex-valued spatial observations
    in the short time Fourier transform (STFT) domain at test time. Extensive simulations
    confirm, that the integrated model outperforms (a) a deep clustering model with
    a subsequent beamforming step and (b) an EM-based model with a beamforming step
    alone in terms of signal to distortion ratio (SDR) and perceptually motivated
    metric (PESQ) gains. ASR results on a reverberated dataset further show, that
    the aforementioned gains translate to reduced word error rates (WERs) even in
    reverberant environments.

  text: 'In this contribution we show how to exploit text data to support word discovery
    from audio input in an underresourced target language. Given audio, of which a
    certain amount is transcribed at the word level, and additional unrelated text
    data, the approach is able to learn a probabilistic mapping from acoustic units
    to characters and utilize it to segment the audio data into words without the
    need of a pronunciation dictionary. This is achieved by three components: an unsupervised
    acoustic unit discovery system, a supervisedly trained acoustic unit-to-grapheme
    converter, and a word discovery system, which is initialized with a language model
    trained on the text data. Experiments for multiple setups show that the initialization
    of the language model with text data improves the word segementation performance
    by a large margin.'

  text: This paper presents an end-to-end training approach for a beamformer-supported
    multi-channel ASR system. A neural network which estimates masks for a statistically
    optimum beamformer is jointly trained with a network for acoustic modeling. To
    update its parameters, we propagate the gradients from the acoustic model all
    the way through feature extraction and the complex valued beamforming operation.
    Besides avoiding a mismatch between the front-end and the back-end, this approach
    also eliminates the need for stereo data, i.e., the parallel availability of clean
    and noisy versions of the signals. Instead, it can be trained with real noisy
    multichannel data only. Also, relying on the signal statistics for beamforming,
    the approach makes no assumptions on the configuration of the microphone array.
    We further observe a performance gain through joint training in terms of word
    error rate in an evaluation of the system on the CHiME 4 dataset.

  text: 'Acoustic beamforming can greatly improve the performance of Automatic Speech
    Recognition (ASR) and speech enhancement systems when multiple channels are available.
    We recently proposed a way to support the model-based Generalized Eigenvalue beamforming
    operation with a powerful neural network for spectral mask estimation. The enhancement
    system has a number of desirable properties. In particular, neither assumptions
    need to be made about the nature of the acoustic transfer function (e.g., being
    anechonic), nor does the array configuration need to be known. While the system
    has been originally developed to enhance speech in noisy environments, we show
    in this article that it is also effective in suppressing reverberation, thus leading
    to a generic trainable multi-channel speech enhancement system for robust speech
    processing. To support this claim, we consider two distinct datasets: The CHiME
    3 challenge, which features challenging real-world noise distortions, and the
    Reverb challenge, which focuses on distortions caused by reverberation. We evaluate
    the system both with respect to a speech enhancement and a recognition task. For
    the first task we propose a new way to cope with the distortions introduced by
    the Generalized Eigenvalue beamformer by renormalizing the target energy for each
    frequency bin, and measure its effectiveness in terms of the PESQ score. For the
    latter we feed the enhanced signal to a strong DNN back-end and achieve state-of-the-art
    ASR results on both datasets. We further experiment with different network architectures
    for spectral mask estimation: One small feed-forward network with only one hidden
    layer, one Convolutional Neural Network and one bi-directional Long Short-Term
    Memory network, showing that even a small network is capable of delivering significant
    performance improvements.'
