Visual information can be provided to blind users through sensory substitution devices that convert images into sound. Through extensive use to develop expertise, some blind users have reported visual experiences when using such a device. These blind expert users have also reported visual phenomenology to other sounds even when not using the device. The blind users acquired synthetic synaesthesia, with visual experience evoked by sounds only after gaining such expertise. Sensorimotor learning may facilitate and perhaps even be required to develop expertise in the use of multimodal information. Furthermore, other areas where expertise is acquired in dividing attention amongst cross-modal information or integrating such information might also give rise to synthetic synaesthesia.
通过将图像转换为声音的感觉替代设备，可以向盲人用户提供视觉信息。一些盲人用户在使用此类设备时报告了视觉体验，通过广泛使用来发展专业技能。这些盲人专家用户甚至在不使用设备时也会报告视觉现象学，以及其他声音。盲人用户获得了合成联觉，只有在获得这种专业知识后，声音才能引起视觉体验。感觉运动学习可能有助于并可能需要发展使用多模态信息的专业知识。此外，在跨模态信息中分配注意力或整合此类信息方面获得专业知识的其他领域也可能导致合成联觉。
