The team is working on giving it the ability to shape its lips and
produce vowels and consonants, in a bid to produce increasingly human - like speech.
When
we produce a vowel, the vocal tract (throat and oral cavity) behaves like a system of moving pipes with specific resonances.
Each of the tubes is shaped after acoustic filters that
produce vowel - like sounds when used in combination with a reed.

vowel.
Hyperarticulation of
vowels may be the aspect of IDS that assists spoken language acquisition (Kuhl et al. 1997) and the speaker's hyperarticulation may be mediated by the perceived linguistic capacity of the receiver; evidence that supports this view is provided by a study that compared speech
produced to dogs, parrots and infants.
