Speak exercise setup and form cues aloud with AVSpeechSynthesizer: - Library detail: a speaker toolbar button reads the full reference aloud. - Active workout: an opt-in "Speak Exercise Cues" setting speaks a brief cue (Setup/Execution/Cues) when an exercise starts, hands-free. - Settings › Voice: pick the voice (auto-prefers an installed enhanced/ premium English voice), a premium-download nudge shown only while on a basic voice, and a Speed/Pitch/Volume sheet with Reset to Defaults. On-device and offline; ducks other audio rather than stopping it. iPhone only for now. Shared SpeechSettings is the single source of truth for the voice/prosody, read fresh per utterance so changes preview live. Claude-Session: https://claude.ai/code/session_01BQcEWmAPA78338QuEwRkAh
