TLDR
Progress of the sound scene database collection project and application to environment sound recognition and hands-free speech recognition are described.Abstract:Â
The sound data for open evaluation is necessary for studies such as sound source localization, sound retrieval, sound recognition and hands-free speech recognition in real acoustic environments. This paper reports on our project for acoustic data collection. There are many kinds of sound scenes in real environments. The sound scene is specified by sound sources and room acoustics. The number of combinations of the sound sources, source positions and rooms is huge in real acoustic environments. We assumed that the sound in the environments can be simulated by convolution of the isolated sound sources and impulse responses. As an isolated sound source, hundred kinds of environment sounds and speech sounds are collected. The impulse responses are collected in various acoustic environments. Additionally we collected sounds from a moving source. In this paper, progress of our sound scene database collection project and application to environment sound recognition and hands-free speech recognition are described.read more

Microphone Position Realignment by Extrapolation of Virtual Microphone
TL;DR: Phase extrapolation using the virtual microphone technique is applied to the virtual realignment of a microphone in such an array for restoring ITD and the interaural cross correlations of the two signals suggest that sound images will be perceived on both the left and right of a listener.

Talker localization based on the combination of DOA estimation and statistical sound source identification with microphone array
TL;DR: A new talker localization algorithm consisting of two algorithms consisting of DOA (direction of arrival) estimation algorithm for multiple sound source localization based on CSP (cross-power spectrum phase) coefficient addition method and statistical sound source identification algorithm based on GMM (Gaussian mixture model) for localizing the target talker position among localized multiple sound sources.
