Recurrence plot embeddings as short segment nonlinear features for multimodal speaker identification using air, bone and throat microphones

Abstract Speech is produced by a nonlinear, dynamical Vocal Tract (VT) system, and is transmitted through multiple (air, bone and skin conduction) modes, as captured by the air, bone and throat microphones respectively. Speaker specific characteristics that capture this nonlinearity are rarely used...
