1// nx_skill_coach_speech.nx -- SKILL-COACH audio-PROSODY adapter (the operator's "convincing capability in how i 2// speak" + the hypnotist's voice + public speaking/acting). SENSOR-coach: from prosodic features (pace, pitch- 3// variety, pause-control, fillers) -> grade each dimension -> diagnose -> DRILL. Perception composes the gated audio 4// stack (nx_pitch over time = pitch-variety + energy/silence = pauses; fillers via ASR = a later rung); here features 5// are passed in (like R1 passed known F0s). Thresholds inline at R1 (-> R2 rubric-store, rule#11). NO floats. 6// Self-gate: 3 speaker profiles (confident / nervous / hesitant) -> correct issue diagnosis. license_tier: ORIGINAL 7import "nx_syscalls.nx" 8import "nx_itoa_lib.nx" // shared MSB-first emitter (zero-alloc) 9 10const PACE_LO: i64 = 110 // words/min: < = too slow 11const PACE_HI: i64 = 170 // > = too fast 12const PITCH_VAR_MIN: i64 = 200 // cents range of speaking pitch: < = monotone 13const PAUSE_LO: i64 = 8 // % time in pauses: < = rushed 14const PAUSE_HI: i64 = 30 // > = hesitant 15const FILLER_HI: i64 = 4 // fillers per 100 words: > = too many 16 17func sp_puts(s: *u8) -> i64 { var n: i64 = 0; while s[n] != (0 as u8) { n = n + 1 } sys_write(1, s, n); return 0 } 18// MIGRATED to the shared emitter (debt 1785563586).
