new, experimental build of SpeechPlayer. I would like those who are brave to test, for a new, more Eloquence-like sound. Shoutout does go out to @fastfinge for helping to get this idea going and colaborating on the repository.

The big switch is that it is no longer a sawtooth wave. Instead, it now uses asymmetric cosine glottal-flow pulse (a pitch-synchronous "glottal pulse train"). So, glottal flow pulses, not continuous oscillator shapes like triangle/saw/square. This has allowed us to achieve a much smoother voice, with clearer consonants but the familiarity of the voice people know.
