Audio slots
Audio slots for visually impaired players are a niche product. Are there any platforms with full voice navigation? Very rarely. Some developers (for example, Microgaming) have created a few slots with screen reader support, but full voice navigation of the casino interface is usually lacking. You can use a screen reader on your phone (VoiceOver, TalkBack), but many elements become awkward to navigate. Should you trust such interfaces? If the platform is licensed, this doesn't affect fairness, but the risk of error due to the lack of visual control is high. I don't know of any specialized platforms, but https://allspinsau.com/en-au/ , the best online casino today, has an accessibility mode with larger buttons and better contrast, but it doesn't offer full voice navigation. For the visually impaired, it's better to use an assistant.
