Dataset Card for Cardiff Conversation Database (CCDb)

The Cardiff Conversation Database (CCDb) provides a non-scripted, audio-visual natural conversation database where neither participant's role is predefined (i.e. speaker/listener). This database will be a useful resource for the computer vision, affective computing, and cognitive science communities to both analyse natural dyadic conversational data and develop conversation models.

Although the project captured both 2D and 3D data, only the 2D data is provided here.

Dataset Creation

The database currently consists of 44 conversations between pairs of speakers, each lasting approximately five minutes. There were 16 speakers in total, 12 male and 4 female, between the ages of 5 and 56 (hence, some speakers were paired multiple times with different conversational partners).

Some conversations have annotations for facial expressions, verbal and non-verbal utterances, and transcribed speech.

Data acquisition

Two 3dMD dynamic scanners captured 3D video, a Basler A312fc firewire CCD camera captured 2D colour video at standard video frame rate, and a microphone placed in front of the participant, out of view of the camera, captured sound (at 44.1KHz).

To ensure all audio and video could be reliably synchronized, each speaker had a handheld buzzer and LED (light emitting diode) device, used to mark the beginning of each recording session. A single button controlled both devices and simultaneously activated the buzzer and LED. No equipment was altered between the recording sessions, except for the height of the chair to ensure the speaker's head was clearly visible by the cameras.
