Thanking Arne Hasselbring for the idea of making a separate module that communicates via tokio. What I can do as a novice is still limited, but this should make it easier to apply improvements later on. This version uses a basic TTS library that interface with common screen readers on multiple platforms (e.g. Speech Dispatcher).
HOLD mode will delay all messages while Spacebar is pressed until Spacebar is released.

As promised, I am back with a rewritten version of the text-to-speech extension.
This now runs as a separate module that communicates with the rest of the runtime via
tokio, resolving some inter-thread communication issues I had encountered with the earlier version.This still relies on simple TTS backends such as Speech Dispatcher, favoring simplicity over fancy but heavy neural models. (The modular structure makes it easy for an interested person to use a different Rust library, if so desired. Speech Dispatcher on Linux is also extensible with more advanced voice engines installed on the user's system.)
What has currently been implemented:
Compilation on Linux requires the development headers for Speech Dispatcher (listed on APT as
libspeechd-dev, I assume they'll be on other package managers as well).A compiled Linux build has no extra requirements to run, compared to the "normal" GC.
The
ttscrate description says it is compatible with other text-to-speech backends on other operating systems, so this should work on Windows or Mac with a different setup rather than Speech Dispatcher in theory, but I don't know any specifics as I haven't tested any other OS yet.Also, note that this branch adds the
ttscrate as a dependency, which should be automatically taken care of by cargo when compiling.This pull request and the associated branch on my fork repo count as the code release for the corresponding RoboCup 2025 Open Research Challenge entry.
