Spatial Diarization for Meeting Transcription with Ad-Hoc Acoustic Sensor Networks

no code implementations27 Nov 2023 Tobias Gburrek, Joerg Schmalenstroeer, Reinhold Haeb-Umbach

We propose a diarization system, that estimates "who spoke when" based on spatial information, to be used as a front-end of a meeting transcription system running on the signals gathered from an acoustic sensor network (ASN).

LibriWASN: A Data Set for Meeting Separation, Diarization, and Recognition with Asynchronous Recording Devices

1 code implementation21 Aug 2023 Joerg Schmalenstroeer, Tobias Gburrek, Reinhold Haeb-Umbach

We present LibriWASN, a data set whose design follows closely the LibriCSS meeting recognition data set, with the marked difference that the data is recorded with devices that are randomly positioned on a meeting table and whose sampling clocks are not synchronized.

A Meeting Transcription System for an Ad-Hoc Acoustic Sensor Network

no code implementations2 May 2022 Tobias Gburrek, Christoph Boeddeker, Thilo von Neumann, Tobias Cord-Landwehr, Joerg Schmalenstroeer, Reinhold Haeb-Umbach

We propose a system that transcribes the conversation of a typical meeting scenario that is captured by a set of initially unsynchronized microphone arrays at unknown positions.

On Synchronization of Wireless Acoustic Sensor Networks in the Presence of Time-varying Sampling Rate Offsets and Speaker Changes

1 code implementation25 Oct 2021 Tobias Gburrek, Joerg Schmalenstroeer, Reinhold Haeb-Umbach

A wireless acoustic sensor network records audio signals with sampling time and sampling rate offsets between the audio streams, if the analog-digital converters (ADCs) of the network devices are not synchronized.

Iterative Geometry Calibration from Distance Estimates for Wireless Acoustic Sensor Networks

1 code implementation11 Dec 2020 Tobias Gburrek, Joerg Schmalenstroeer, Reinhold Haeb-Umbach

In this paper we present an approach to geometry calibration in wireless acoustic sensor networks, whose nodes are assumed to be equipped with a compact microphone array.
