We have seen in previous section that attention focuses on nouns and Table 2 suggests that these nouns correspond to the main concept of the paired image. To confirm this trend, we experiment on a crosslingual speech-to-speech retrieval task using images as pivots. This possibility was introduced in<cite> [8]</cite> , but required training jointly or alternatively two speech encoders within the same architecture and a parallel bilingual speech dataset while we experiment with separately trained models for both languages.
