As reported by [gamasutra]:
The [Video Accessibility Act] of 2010 signed by Barack Obama requires that communication functionality like in-game chat and the UI used to navigate to those elements must be accessible for people with visual, motor, speech, cognitive, or sensory difficulties, with these rules applying to companies who do business in the US. The gaming industry has had several waiver extentions for compliance against these stanards since it was signed into law, to better negotiation and determine implementation of these rules with [ESA members]. The final waiver has now expired. Now any game released after December 31 2018 is required to be CVAA compliant if they include communications features covered in the CVAA, as far as is achievable within reasonable effort and expense, or otherwise unduly burdensome at that point of the development cycle to implement.
For some examples on companies that have already met compliance, there's [Verizons] text to speech set top boxes, which has enabled subtitles on all broadcast content for streaming services like Netflix and Hulu. Games including Halo Wars 2, Forza Horizon 4, and Battlefield 5, along with a [number] [of] [developers] getting involved, and the development of both Xbox and PS4 Text to Speech, with the release of Xbox's API for UI, and transcription API for two way conversion between voice and text chat last year.
If you find that a product or company does not meet those standards for accessing communications, you can either get in touch with the company directly through the phone number they have registered with the FCC, or contact the FCC directly. When contacting the FCC you'll be required to send over details of the issue and how it could be fixed; the FCC can then act as mediators and open a line of dialogue between you and the company. The company will then be gien a 30 day window to resolve your issue, if it isn't resolved after 30 days you can either extend the window to give them more time, if for example they've agreed a solution but won't be released until the next scheduled patch in three months time, or escalate it to a full complaint, though a full complaint consists of a full six month investigation. Fines for non-compliance start at 100,000$ for each violation, or for each day of an ongoing violation, going as high as 1 million. Its worth noting that to date, no dispute has escalated towards fines.
For further information on what you can do if your concerned about the accessibility of an advanced communications product or service (in the US), check [here]. If your also interested in hearing more about what the CVAA is all about, you can check out [this] IGDA presentation video, or [this] pda.
NOTE: That these regulations only apply to communications functionality (text chat, voice chat, video chat), and any menu's or information needed to navigate to and use those functions. You can't raise any issues about anything that isn't related to such communications.
