A harsh, low-vowel language, K'kr'frr utilizes buzzing, whirring, chirping and clicking noises, as well as a very complex system of pauses, half-pauses, and quarter pauses between words. As some words require simultaneous clicks of differing frequency (by clicking the mandibles, jaws, and claws), or the ability to click while making another noise, it is virtually impossible for non-Odarites to speak the language fluently without external hardware.
