  text: In this paper we present our experimental results about classifying audio
    data into broad acoustic categories. The reverberated sound samples from indoor
    recordings are grouped into four classes, namely speech, music, acoustic events
    and noise. We investigated a total of 188 acoustic features and achieved for the
    best configuration a classification accuracy better than 98\%. This was achieved
    by a 42-dimensional feature vector consisting of Mel-Frequency Cepstral Coefficients,
    an autocorrelation feature and so-called track features that measure the length
    of ''traces'' of high energy in the spectrogram. We also found a 4-feature configuration
    with a classification rate of about 90\% allowing for broad acoustic category
    classification with low computational effort.

  text: For an environment to be perceived as being smart, contextual information
    has to be gathered to adapt the system's behavior and its interface towards the
    user. Being a rich source of context information speech can be acquired unobtrusively
    by microphone arrays and then processed to extract information about the user
    and his environment. In this paper, a system for joint temporal segmentation,
    speaker localization, and identification is presented, which is supported by face
    identification from video data obtained from a steerable camera. Special attention
    is paid to latency aspects and online processing capabilities, as they are important
    for the application under investigation, namely ambient communication. It describes
    the vision of terminal-less, session-less and multi-modal telecommunication with
    remote partners, where the user can move freely within his home while the communication
    follows him. The speaker diarization serves as a context source, which has been
    integrated in a service-oriented middleware architecture and provided to the application
    to select the most appropriate I/O device and to steer the camera towards the
    speaker during ambient communication.

  text: Microphone arrays represent the basis for many challenging acoustic sensing
    tasks. The accuracy of techniques like beamforming directly depends on a precise
    knowledge of the relative positions of the sensors used. Unfortunately, for certain
    use cases manually measuring the geometry of an array is not feasible due to practical
    constraints. In this paper we present an approach to unsupervised shape calibration
    of microphone array networks. We developed a hierarchical procedure that first
    performs local shape calibration based on coherence analysis and then employs
    SRP-PHAT in a network calibration method. Practical experiments demonstrate the
    effectiveness of our approach especially for highly reverberant acoustic environments.

  text: In this paper we present a system for identifying and localizingspeakers using
    distant microphone arrays and a steerablepan-tilt-zoom camera. Audio and video
    streams are processedin real-time to obtain the diarization information {grqq}who
    speakswhen and where'' with low latency to be used in advanced videoconferencing
    systems or user-adaptive interfaces. A key featureof the proposed system is to
    first glean information about thespeaker{\rq}s location and identity from the
    audio and visual datastreams separately and then to fuse these data in a probabilisticframework
    employing the Viterbi algorithm. Here, visual evidenceof a person is utilized
    through a priori state probabilities,while location and speaker change information
    are employedvia time-variant transition probablities. Experiments show thatvideo
    information yields a substantial improvement comparedto pure audio-based diarization.

abstract:
- lang: eng
  text: In this paper we consider the problem of detecting speaker changes in audio
    signals recorded by distant microphones. It is shown that the possibility to exploit
    the spatial separation of speakers more than makes up the degradation in detection
    accuracy due to the increased source-to-sensor distance compared to close-talking
    microphones. Speaker direction information is derived from the filter coefficients
    of an adaptive Filter-and-Sum Beamformer and is combined with BIC analysis. The
    experimental results reveal significant improvements compared to BIC-only change
    detection, be it with the distant or close-talking microphone.
