Crate prani 

prani — Creature and Animal Vocal Synthesis

prani (Sanskrit: living being / creature) provides vocal synthesis for non-human creatures: animals, fantasy beings, and alien species. Built on svara’s formant synthesis engine with species-specific vocal tract models, call pattern generators, and behavioral vocalization mapping.

Architecture

CreatureVoice (species params)
      |
      v
svara::GlottalSource → CreatureTract → Call Pattern → Output
  (excitation)         (species tract)  (vocalization)

Key Concepts

• Species: Defines vocal tract geometry, f0 range, and available call types
• CreatureVoice: Instance of a species with individual variation
• Vocalization: A call pattern (growl, chirp, howl, roar, hiss, purr)
• CallIntent: Why the creature is vocalizing (alarm, territorial, mating, pain, idle)

Quick Start

use prani::prelude::*;

// Create a wolf voice and synthesize a howl
let voice = CreatureVoice::new(Species::Wolf);
let samples = voice.vocalize(
    &Vocalization::Howl,
    44100.0,
    2.0,  // 2 seconds
).expect("synthesis should succeed");
