Universal Transcription System (Jörg Rhiemeier)

For many years, Jörg Rhiemeier used a Universal Transcription System to transcribe all his conlangs. Today, with a more refined understanding of phonology, he no longer uses this system as such, but designs transcriptions according to the phonological needs of the languages, though some of the transcriptions Jörg uses for his conlangs are still loosely based on it. The transcription system is charted below.

Consonants

	Labial	Dental	Alveolar	Postalveolar	Palatal	Velar	Glottal
Voiceless stops	p	t				k	'
Voiced stops	b	d				g
Voiceless fricatives	f	th	s	sh	jh	kh	h
Voiced fricatives	v	dh	z	zh		gh
Nasals	m	n			nj	ng
Laterals		l			lj
Rhotics		r
Semivowels	w				j

In an early version, r was used for a voiced velar fricative, reflecting an idiosyncrasy of the author's native idiolect!

Obviously, this misses several entire places (e.g., retroflex, uvular, pharyneal) and manners of articulation (e.g., lateral fricatives, ejectives, implosives, clicks) of whose existence the author wasn't aware back then.

Vowels

	Front unround	Front round	Central unround	Back round
High	i	y		u
Mid	e	oe		o
Low	ae		a	ao

Again, many possible vowels are not covered.
