In this paper, we explore the learning of neural network embeddings for natural images and speech waveforms describing the content of those images. These embeddings are learned directly from the waveforms without the use of linguistic transcriptions or conventional speech recognition technology. While prior work has investigated this setting in the monolingual case using English speech data, this work represents the first effort to apply these techniques to languages beyond English. Using spoken captions collected in English and Hindi, we show that the same model architecture can be successfully applied to both languages. Further, we demonstrate that training a multilingual model simultaneously on both languages offers improved performance over the monolingual models. Finally, we show that these models are capable of performing semantic cross-lingual speech-to-speech retrieval.

本文讨论了在自然图像和描述这些图像内容的语音波形中学习神经网络嵌入的方法。我们展示了这些技术可成功应用于英语和印地语等多种语言，通过在两种语言上同时进行训练，可以提高模型的性能，并且这些模型可以执行语义跨语言语音检索。
