RealVAD: A Real-world Dataset for Voice Activity Detection

<p><strong>RealVAD: A Real-world Dataset for Voice Activity Detection</strong></p> <p>The task of automatically detecting &ldquo;Who is Speaking and When&rdquo; is broadly named as Voice Activity Detection (VAD). Automatic VAD is a very important task and also the foundation of several domains, e.g., human-human, human-computer/ robot/ virtual-agent interaction analyses, and industrial applications.</p> <p>RealVAD dataset is constructed from a YouTube video composed of a panel discussion lasting approx. 83 minutes. The audio is available from a single channel. There is one static camera capturing all panelists, the moderator and audiences.</p> <p>Particular aspects of RealVAD dataset are:</p> <ul> <li>&nbsp;It is composed of panelists with different nationalities (British, Dutch, French, German, Italian, American, Mexican, Columbian, Thai). This aspect allows studying the effect of ethnic origin variety to the automatic VAD.</li> <li>&nbsp;There is a gender balance such that there are four female and five male panelists.</li> <li>&nbsp;The panelists are sitting in two rows and they can be gazing audience, other panelists, their laptop, the moderator or anywhere in the room while speaking or not-speaking. Therefore, they were captured not only from frontal-view but also from side-view varying based on their instant posture and head orientation.</li> <li>&nbsp;The panelists are moving freely and are doing various spontaneous actions (e.g., drinking water, checking their cell phone, using their laptop, etc.), resulting in different postures.</li> <li>&nbsp;The panelists&rsquo; body parts are sometimes partially occluded by their/other&#39;s body part or belongings (e.g., laptop).</li> <li>&nbsp;There are also natural changes of illumination and shadow rising on the wall behind the panelists in the back row.</li> <li>&nbsp;Especially, for the panelists sitting in the front row, there is sometimes background motion occurring when the person(s) behind them moves.</li> </ul> <p>The annotations includes:</p> <ul> <li>&nbsp;The upper body detection of nine panelists in bounding box form.</li> <li>&nbsp;Associated VAD ground-truth (speaking, not-speaking) for nine panelists.</li> <li>&nbsp;Acoustic features extracted from the video: MFCC and raw filterbank energies.</li> </ul> <p><em>All info regarding the annotations are given in the ReadMe.txt and Acoustic Features README.txt files.</em></p> <p><strong>When using this dataset for your research, please cite the following paper in your publication:</strong></p> <ol> <li>C.
