[Espeak-general] Faster speaking

[Jonathan D. <jo...@ta...>]

I have made some changes which I hope give a small improvement to
eSpeak at faster speeds.  Also I have increased the speed range to 80
to 450 words-per-minutes, with a default of 175 wpm.

These changes are in eSpeak version 1.43.46 at:

I think the speech is better at 390 wpm (which was the previous maximum
setting).  However, I can't understand the speech at 450 wpm, so I
don't know whether that's useful.

Do the Klatt synthesizer voice variants sound better than the original
eSpeak synthesizer at high speeds?

Speeds and intelligibility may vary for different language voices.
