software × hardware

Hello, I'm Pawel

engineer, developer & tinkerer

I build across software and hardware—from speech synthesiser emulation to macOS apps and browser-based engineering tools.

Built to solve real problems.

Featured project · Speech synthesis

Preserving Hawking's voice.

I helped recreate the Speech Plus CallText 5010 synthesiser in software, preserving the voice Professor Stephen Hawking recognised as his own. He used the emulator as his primary voice for the last two months of his life.

Building on years of work by Peter Benie and others, the project combined DSP emulation adapted from higan with Peter's CPU emulator. My work included analysing the hardware, validating the emulated voice against it, and getting the software running under Windows using WSL.
