I have been trying to squeeze TTS stack down far enough to run in a $3 chip which has 512kb of SRAM without NPU. While trying to get to that milestone i built sanoTTS which has - 11 voices, 6 languages - params size ranging from 294k - 2.2m. For comparison we are 244x smaller than kokoro, 9000x sma…
