10. A method performed at a system that includes an implantable auditory prosthesis and an external device, comprising: receiving speech signals forming part of a voice call; analyzing, at the external device, the received speech signals; sending the speech signals to the implantable auditory prosthesis for use in generating stimulation signals representative of the received speech signals, wherein delivery of the stimulation signals to the recipient results in reduced tonal perception of the received speech signals; displaying, at the external device, a graphical representation comprising a humanoid avatar that includes at least a head with a mouth region, wherein the humanoid avatar enables the recipient of the implantable auditory prosthesis to compensate for the reduced tonal perception associated with delivery of stimulation signals representative of the speech signals; performing speech to lip movement synthesis of the received speech signals; and animating the mouth region of the avatar based on the received speech signals so as to emulate vocal articulator movements of a speaker of the received speech signals.
