Script chamber
Paste a line, a poem, or a script. The page turns words into phoneme groups, renders them with a local formant engine, and can export either audio or a moving soundmap.
retro formant speech / local synth / MP3 / MP4
Low Quality Robot Text to Speech
Type a script, press play, and the browser breaks the words into pronounceable sounds, feeds them to a local formant synthesizer, and renders a rough late-70s computer voice.
Words become phonemes
The script is split into pronounceable sound groups before it reaches the synthesizer.
Browser-only render
The formant synth runs locally. Your text does not need a server round trip to become audio.
Retro by design
It is not polished neural speech. It is a brittle, direct, low-quality robot voice for character and texture.
MP3 or MP4 export
Download the dry robot voice as audio, or render a cobalt soundmap video in the same visual system as this page.

Questions from the machine room
Is this a natural-sounding TTS model?
No. The charm is the rough robotic formant sound. It is useful when you want texture, not a polished assistant voice.
Does the page upload my text?
No. The speech conversion, playback, and MP3 render happen locally in the browser.
What happens before synthesis?
The page converts visible words into phoneme groups, applies the selected voice contour, then schedules those targets through the formant engine.
What should I export?
Use MP3 when you only need the voice. Use MP4 when the soundmap itself should become the visual artifact.
