Are you a Werewolf? Detecting deceptive roles and outcomes in a conversational role-playing game

Abstract

This paper addresses the task of automatically detecting outcomes of social interaction patterns, using non-verbal audio cues in competi- tive role-playing games (RPGs). For our experiments, we introduce a new data set which features 3 hours of audio-visual recordings of the popular “Are you a Werewolf?” RPG. Two problems are ap- proached in this paper: Detecting lying or suspicious behavior using non-verbal audio cues in a social context and predicting participants’ decisions in a game-day by analyzing speaker turns. Our best clas- sifier exhibits a performance improvement of 87% over the baseline for detecting deceptive roles. Also, we show that speaker turn based features can be used to determine the outcomes in the initial stages of the game, when the group is large.

Sound recording and reproduction

Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves.

Mastering (audio)

Mastering, a form of audio post production, is the process of preparing and transferring recorded audio from a source containing the final mix to a data storage device (the master), the source from which all copies will be produced (via methods such as pressing, duplication or replication). In recent years digital masters have become usual, although analog masters—such as audio tapes—are still being used by the manufacturing industry, particularly by a few engineers who specialize in analog mastering.

Delay (audio effect)

Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo-like effect, whereby the original audio is heard followed by the delayed audio. The delayed signal may be played back multiple times, or fed back into the recording, to create the sound of a repeating, decaying echo. Delay effects range from a subtle echo effect to a pronounced blending of previous sounds with new sounds.
