As the world's population increases, the number of languages increases. The comfortable size for a language-community is about 5000 speakers, although this varies with the nature, occupation and organization of the communities. Within communities, people talk without lators. Intimate family exchanges, emotional talk, banter between friends and lovers, poetry and song come across poorly through lators. But for intercommunity trade and diplomacy, communication through lators is preferred, being well-suited to the transmission of factual information without emotional overtones and nuances.
Normal children learn the language of their own community without lators.
Unusual children, like Knox, who have learnt their language via lators sometimes have emotional problems, are withdrawn and have difficulty forming close relationships. But this is only a tendency. There are contented, well-adjusted people who have learned their first language through lators. Since he had been brought up with lators, Knox had a lator-like voice quality which he could never fully lose. Endogamy is common because of the cultural isolation of the clans, but exogamous conception, using artificial insemination, is also practised, as is adoption.
