v0.12.0

Added

• saymo/tts/naturalness.py — single source of truth for XTTS prosody presets and helpers used by every TTS-generation script in the repo. Exports NATURAL_PRESET, CONSERVATIVE_PRESET, ENERGETIC_PRESET, resolve_voice_sample(language) (per-language reference fallback), load_breath_sample() (extracts a real inhale from the user's voice sample to splice between paragraphs instead of digital silence), split_for_tts(text) (sentence/paragraph/[pause:N]-aware splitter), and shared inter-segment pause constants.
• docs/VOICE-NATURALNESS.md — consolidated rulebook (reference recording specs, source-text rules, XTTS parameter cheat-sheet, fine-tuning, WER-based quality verification via Whisper). Distilled from ElevenLabs, Inworld AI, and Coqui XTTS-v2 official guides plus internal experiments.
• scripts/synthesize_presentation.py — one-shot helper that synthesizes presentation text in the user's cloned voice. Uses the shared naturalness module, supports --preset natural|conservative|energetic, --language, and [pause:N] markers.
• scripts/play_to_glip.py — standalone "press button → talk to Glip" runner: stashes the currently-selected Glip mic, switches to BlackHole 2ch, plays a WAV via the existing provider unmute → speak → mute flow, then restores the original mic. Includes a global stop hotkey (Cmd+Shift+X by default), Ctrl+C handler that re-mutes Glip and restores the mic, and --mic-back override.
• get_current_rc_mic() in saymo/glip_control.py — reads the currently-selected microphone label from the Glip audio dropdown via Chrome JS injection; used by play_to_glip.py to remember the user's real mic across a playback.
• XTTS prosody kwargs forwarding in saymo/tts/coqui_clone.py — CoquiCloneTTS.synthesize(text, **kwargs) now passes speed, temperature, repetition_penalty, length_penalty, top_k, top_p, enable_text_splitting straight through to XTTS for both base and fine-tuned checkpoints.

Changed

• switch_rc_mic_to_blackhole() generalised to switch_rc_mic_to(device_name) in saymo/glip_control.py — accepts any substring of a Glip mic-dropdown label (e.g. "BlackHole 2ch", "MacBook Pro Microphone", "AirPods"). Old function kept as a backwards-compatible wrapper.
• GlipProvider.switch_mic(device_name) now actually honours its device_name argument (previously hardcoded to BlackHole 2ch regardless).
• CLAUDE.md + AGENTS.md — added architectural rule that TTS-generation code must import presets/helpers from saymo/tts/naturalness.py rather than re-deriving constants per-script.
