Pronunciation schemes

Due to the anatomic variety of the Novan population, the Novan language has many pronunciation schemes. While the most common, the tongue and teeth, is a sound-based scheme (as we'd expect when using the term "pronunciation"), some variants use other supports like gestures, visible light emissions, non-visible electromagnetic waves, pheromones, etc..

There is a direct correspondence between the various pronunciation schemes, allowing a direct and simple transformation from one to the other. It also facilitate the use of the phonetic-based writing system and its alphabet.

Major pronunciation schemes
The 4 main pronunciation schemes are: This list is not exhaustive, and mostly contains sound-based variants.
 * the sound-based tongue and teeth;
 * the sound-based whistley beak;
 * the sound-based clank rhythm;
 * the gesture-based articulated dance.

Origin
The Novan linguists in charge of creating the language created a variety of pronunciation schemes based on their astrobiologic knowledge. They even included encoding of the language using phenomena not yet witnessed as a communication tool of sentient species, in a just-in-case approach. Some schemes are sometimes added to the list upon the discovery of unexpected communication supports, as a way to study the possibilities of said supports.

Daily use
The tongue and teeth is used as the main communication mean, as it matches most of the Novan population.

Most of the other pronunciation schemes are not used in practice, as the individuals unable to produce the right range of sounds quickly mutate to acquire the right sound generation tools, and being supplied personalized translation tools in the meantime.

One of the few exception is their use in external Novan colonies populated by sentients not possessing their own language, as a temporary solution, while greatly encouraging the creation of a local language.

Use as a quick encryption method
Some Novans exploit the scare use of non-tongue and teeth pronunciation schemes as a quick encryption method for messages or marks with low security requirements. This use especially fits messages targeting fellow Novans or discrete markings of the environment.

While extremely easy to break using pattern-matching, this encryption method exploits the unexpectedness of using the support as a communication material, thus putting the over-zealousness of Novan linguists to use for hiding information.
