This is imho not true. All our targets should have enough
processing power to run realtime TTS. A plain Amiga 500 (7MHz
MC68000, 512KB of RAM) was able to do it in the 80s, with a
narrator.device of ~64KB and a translator.library of ~13KB.
(Note: These are enhanced versions - the original AmigaOS 1.3
versions were probably still smaller)

The biggest hurdle on archos was the inability to play PCM
samples - but that's possible now thanks to the PCM codec.

The real challenging task now would be to actually write a
compact, efficient, opensource TTS engine, preferably supporting
more than one language.
