Query: Catplayinginthesnow: Impact of Prior Segmentation on a Model of Visually
  Grounded Speech   The language acquisition literature shows that children do not build their
lexicon by segmenting the spoken input into phonemes and then building up words
from them, but rather adopt a top-down approach and start by segmenting
word-like units and then break them down into smaller units. This suggests that
the ideal way of learning a language is by starting from full semantic units.
In this paper, we investigate if this is also the case for a neural model of
Visually Grounded Speech trained on a speech-image retrieval task. We evaluated
how well such a network is able to learn a reliable speech-to-image mapping
when provided with phone, syllable, or word boundary information. We present a
simple way to introduce such information into an RNN-based model and
investigate which type of boundary is the most efficient. We also explore at
which level of the network's architecture such information should be introduced
so as to maximise its performances. Finally, we show that using multiple
boundary types at once in a hierarchical structure, by which low-level segments
are used to recompose high-level segments, is beneficial and yields better
results than using low-level or high-level segments in isolation.
