Yes, it is possible to enable accessibility features like text-to-speech and voice input in Botpress. The team at Botpress is proud of community members who leverage the platform to create innovative solutions like text-to-speech applications. However, I couldn't find specific information about enabling these features in the given context. It would be best to refer to the Botpress documentation or seek assistance from the Botpress community for detailed instructions on how to enable text-to-speech and voice input features.
