The Game Chat feature on the upcoming Nintendo Switch 2 is expected to include support for real-time subtitles and text-to-speech functionality

Upcoming features for the Nintendo Switch 2 indicate support for real-time subtitles and the ability to convert text to speech.
Although not yet officially confirmed by Nintendo, videos showcasing these capabilities have surfaced recently. One demonstrates a function where messages are typed into Game Chat then heard by the recipient as voice output.
Another clip reveals how Game Chat can convert spoken dialogue into written text displayed on-screen.
The console is expected to support USB keyboards like its predecessor, but confirmation is pending.
Initially, Game Chat accessibility will be freely accessible to all users from launch until March 31, 2026. Beyond this point, a Switch Online subscription will be necessary, potentially restricting these features to subscribers. GamesIndustry.biz has inquired with Nintendo for more details.
The Nintendo Switch 2 is planned for release on June 5. Recently, Nintendo emphasized its aim to make the console as available as possible in the face of market fluctuations influenced by US tariffs.
