The developmental origin of language communication seems to involve vocal interactions
between an infant and a caregiver, and one of the big mysteries related to this is how an …

Evidence exists for a form of imitation, vocal segmentation, by a Grey parrot. Data show that
the bird understands that his labels are comprised of individual units that can be recombined …

Inspired by the observation that infants acquire phonemes common to adults without having
the capability to articulate, nor having a priori knowledge about the relationship between the …

It is a formidable issue how robots can show behaviors to be considered as the
corresponding human's ones since the body structure is different between robots and …

Self-supervised learning can significantly improve the performance of downstream tasks,
however, the dimensions of learned representations normally lack explicit physical …

Without any explicit knowledge, human infants acquire the phonemes of adults who have
different articulation parameters. By building a robot that reproduces this developmental …

This paper describes development of a new human-like talking robot WT-4 (Waseda Talker
No. 4). WT-4 was developed to overcome the problems related to the lack of variation in the …

We present a unified approach for speech production and recognition based on articulatory
motor representations. The approach is inspired by the motor theory and the discovery of …

In this paper we describe a novel algorithm, inspired by the mirror neuron discovery, to
support automatic learning oriented to advanced man-machine interfaces. The algorithm …

This paper describes the mechanisms and the speech production of a new advanced talking
robot WT-3 (Waseda Talker-No. 3) that improves on WT-2 (Waseda Talker-No. 2) and is …
