Silencio-2 is an open 18M-parameter TTS that follows inline emotion and sound tags on a laptop CPU
Shown on HN Nov 2, the Kyutai Pocket TTS fine-tune takes tags like [laugh], [sigh] and <whisper> inside the text, clones a voice from a few seconds of audio, and the author says it runs about 20x real time on four Apple M4 CPU threads from one 112 MB file. Weights are CC-BY-4.0, it's English only, and the author notes tags vary by seed and no WER benchmark was run on this checkpoint.
