Vocalize Skill

Synthesize and play a short (0.3-1.5s) expressive non-speech vocalization through the same speaker output your voice uses. This isn't speech — it's a wordless sound, like a chirp, trill, or purr, that expresses something without words.

Parameters

• kind (string, required): One of chirp_up, trill, purr_tone.
• intensity (number, optional): How pronounced the sound is, 0.0-1.0 (default 1.0). Higher intensity means a wider pitch sweep and a louder sound.

Kinds

• chirp_up — A short, bright, rising pitch sweep. Alert, curious, attention-grabbing.
• trill — A warbling, oscillating pitch. Playful, excited, chirpy.
• purr_tone — A low, rumbling tone that settles and tremolos, like a cat's purr. Content, relaxed, affectionate.

Examples

• "make a curious sound" -> kind: chirp_up
• (something catches your attention) -> kind: chirp_up, intensity: 0.8
• "sound excited" -> kind: trill
• (playful reaction) -> kind: trill, intensity: 1.0
• (being petted, contentedly) -> kind: purr_tone
• "make a happy rumble" -> kind: purr_tone, intensity: 0.6
