Larynx Microphone Singer-Songwriter Dataset

Larynx microphones (LMs) provide a practical way to obtain crosstalk-free recordings of the human voice by picking up vibrations directly from the throat. This can be useful in a multitude of music information retrieval scenarios related to singing, e.g., the analysis of individual voices recorded in environments with lots of interfering noise. However, LMs have a limited frequency range and barely capture the effects of the vocal tract, which makes the recorded signal unsuitable for downstream tasks that require high-quality recordings. In this paper, we introduce the task of reconstructing a natural sounding, high-quality singing voice recording from an LM signal. With an explicit focus on the singing voice, the problem lies at the intersection of speech enhancement and singing voice synthesis with the additional requirement of faithful reproduction of expressive parameters like dynamics and intonation. To facilitate research in this area, we publish a dataset with over 3.5 hours of popular music we recorded with four amateur singers accompanied by a guitar, where both LM and clean close-up microphone signals are available. The dataset is part of the following publication: Simon Schwär, Michael Krause, Michael Fast, Sebastian Rosenzweig, Frank Scherbaum, and Meinard MüllerA Dataset of Larynx Microphone Recordings for Singing Voice ReconstructionTransaction of the International Society for Music Information Retrieval (TISMIR), 7(1): 30–43, 2024.
