I have had quite a bit to do with clients who have dyslexia and often are looking at software such as Dragon Naturally Speaking to help them. It does work well too as they can concentrate on what it is they want to say and the software generally addresses the issues of spelling and accuracy and such.
Where issues become difficult is when there is information that needs to be read and understood. Here screen readers can assist. However, I have found that embedding specially designed dyslexic fonts into the computer and software such as Microsoft Word so the fonts are simply another choice in the drop-down font selection box can make a huge difference. Take it a step further and designing templates or altering the main Word template to be set to the font as default all combine to streamline processes and lessen the impact of having to deal with dyslexia.
Processes then in place such as receiving information in documents and emails and instantly copying and pasting them and converting them to the dyslexic font makes reading and taking in the information so much easier. I have put systems and processes in place where this can be done quite quickly and easily and all work I have done with these fonts has made quite a large impact on how these clients manage information and technology. Often a final step of selecting all and then converting back to a standard font like Arial before sending the document or email on is all that is required to complete the full process.
If you are interested, but not sure where to start or how to get the systems and processes in place, we can help get you setup and started.
Some fonts need to be paid for, usually in a one off purchase, however, it does pay to look around. It may be that the open source and free version will met your needs. This can be a useful starting point. https://opendyslexic.org/
