We call for your help with the Japanese translations for project summaries. The submitted translations will be posted after simple evaluation. (Not only the translation itself is going to be checked, but we also make sure it's clear of wiki format problems. Especially problems that are related to the layout, such as line breaks and links, will be checked, so please give heed. When there appears to be a problem with the translation itself or the layout, we may not be able to post your translation. We often see problematic cases related to links. When there's going to be a line of Japanese text right after the URL, please make sure to leave a space to separate.) Also, even with projects that may already have their summaries translated, if you find an outdated translation or typographical errors, please update. Login to start translating. When you are done, you will find your name at the bottom of the summary as the translator.

You are not Logged in. If you submit this translation, your name will not show on the this project page (will be logged as "translated by an anonymous user").

Intelligent systems would benefit from being able to localize and track sound sources in real life settings. Such a capability can help in localizing a person or an interesting event in the environment, and also provides enhanced processing for other capabilities such as speech recognition. To give this capability to a computing system, the challenge is not only to localize simultaneous sound sources, but to track them over time. The ManyEars project propose a robust sound source localization and tracking method using an array of eight microphones. The method is based on a frequency-domain implementation of a steered beamformer along with a particle filter-based tracking algorithm. Tests on a mobile robot show that the algorithm can localize and track in real-time multiple moving sources of different types over a range of 7 meters. These new capabilities allowed the robot to interact using more natural means with people in real life settings. The ManyEars project provides an easy to use C library for microphone array processing. This includes sound source localisation, tracking, and separation.A tuning Qt GUI is also available for fine tuning the parameters.
