Thanks for the honest advice and for sharing your experience. I totally agree that working on speech itself—whether through therapy or training—is vital. In my view, using tools like text or TTS isn't a sign of giving up; it’s part of a holistic approach. It’s about having a 'safety net' while still pushing forward with personal efforts like voice training. The reason I asked this is actually because I'm currently developing an app to support communication. I was curious from a design perspective: which method do people find more reliable or comfortable in the heat of the moment? Your perspective as someone who has struggled with this for a long time is really valuable. Thank you.
