No interpolation needed.\n\n- `word-progress` (Minimax with voice.subtitleType: 'word'): cursor-\n  based word count per TTS segment. Use wordsSpoken as the anchor,\n  interpolate forward using segmentDurationMs or timing.words until\n  the next event arrives.\n\nWhen absent, the event is a text-only fallback for providers without\nword-level timing (e.g. Cartesia, Deepgram, Azure). Text emits once\nper TTS chunk when audio is playing. Optionally interpolate a word\ncursor at ~3.5 words/sec between events for approximate tracking.",
