Voice synthesis engine built in pure Python

Creator notes

I asked Argon to synthesise a voice for itself with code, no libraries, only Python. It pulled this together, step by step: - converted text into phonemes, stress patterns, and connected tongue-tap allophones - built a source-filter foundation from a periodic pitch pulse and cascaded resonators - shaped vocal fold airflow with the Liljencrants-Fant equation and open-phase breath noise - modeled 5 vocal tract chambers, turbulent consonant hiss, and 18ms stop bursts - connected syllables with fifth-degree minimum-jerk curves for smooth tongue and pitch motion - added subglottal windpipe rebound, arched lung-pressure envelopes, and lip radiation physics The video shows the evolution of the voice.
