An anecdote I really like is that when Stephen Hawking identified with his DECtalk voice, and continued to use it for the rest of his life (rather than switching to a newer speech synthesis system at any point).
Quote from the dectalk wikipedia:
DECtalk can be used as part of a speech generating device for those unable to speak. A notable user was Stephen Hawking, who was unable to speak due to a combination of severe disabilities caused by ALS as well as an emergency tracheotomy. Hawking used a version of the DECtalk voice synthesizer for several years and came to be associated with the unique voice of the device. In 2011, Hawking's research assistant Sam Blackburn said Hawking still used a version of DECtalk identified on its board as the "Calltext 5010" manufactured in 1988 by SpeechPlus, Inc, because he identified with it and had not heard a voice he liked better. The CallText 5010 was still listed on Hawking's site as of 2015. A team from Cambridge (UK) and Palo Alto eventually emulated the workings of the CallText 5010 on a Raspberry Pi, which Hawking used from January 2018 to his death in March of that year.
