Conlang X-SAMPA Transcription Scheme

The Conlang X-SAMPA (CXS) transcription scheme is documented by Henrik Theiling. It is used on the conlang mailing list for transcribing the pronunciation of conlangs, but can be used outside that domain. CXS derives from X-SAMPA, making various incompatible changes to X-SAMPA with the intention of making it easier to read by choosing some representations that are closer to the IPA symbols.

This document uses a set of phoneme features based on the features originally developed by Evan Kirshenbaum. These features are described in the phonemes document.

The _ character is used as a tie bar to join two phonemes, as well as the first character in several diacritics. It can be used for affricates and double articulations. The _^ non-syllabic marker can be used for the second vowel in diphthongs.

The ) character is used by CXS as an alternative tie bar that is placed after the second phoneme. This is preferred by CXS as it does not clash with any diacritics. For example, ts) is an affricate and ts is a consonant cluster of t followed by s.

The X-SAMPA - character to differentiate between affricates, double articulations, and diphthongs such as ts and consonant clusters such as t-s is not supported in CXS.

Phoneme Transcription Schemes

BCP47 Subtag Abbreviation Transcription Scheme Encoding
fonipa IPA International Phonetic Alphabet Unicode
fonxsamp X-SAMPA Extended Speech Assessment Methods Phonetic Alphabet ASCII
x-foncxs CXS Conlang X-SAMPA ASCII
x-fonkirsh Kirshenbaum (ASCII-IPA) ASCII
  1. foncxs and fonkirsh are private use extensions defined in the bcp47-extensions file, so have the x- private use specifier before their subtag names.

  1. The X-SAMPA X\ and ?\ are not specified by CXS. Instead, the H\ and <\ consonants are transcribed as fricatives and are included in their places.

  2. \v can also be used for the labio-dental approximant P like in X-SAMPA.

  3. !\` is specific to CXS. It is not listed in the IPA chart either.

  1. 5 is supported as an alternative to l_e due to its use in some language- specific SAMPA phoneme sets.

Manner of Articulation

Feature Symbol Name
ejc _> ejective
imp _< implosive

Vowels

fnt cnt bck
unr rnd unr rnd unr rnd
hgh i y i\ u\ M u
smh I Y I\ U\ U
umd e 2 @\ 8 7 o
mid @
lmd E 9 3 3\ V O
sml & 6
low a &\ A Q

  1. i\ is in common usage in the conlang mailing list, but the X-SAMPA 1 transcription is also supported.

  2. In CXS, the following vowels are different to the X-SAMPA transcriptions: } is replaced by u\, { by &, and & by &\. This makes CXS incompatible with X-SAMPA.

  3. I\ and U\ are not listed in the IPA chart.

Other Symbols

Symbol Features
@` unr mid cnt rzd vwl
3` unr lmd cnt rzd vwl
  1. @` and 3` are not explicitly listed in CXS. The rhoticized diacritic is specified instead.

Diacritics

Articulation

Feature Symbol Name
lgl ◌_N linguolabial
idt interdental
◌_d dental
apc ◌_a apical
lmn ◌_m laminal
◌_+ advanced
◌_- retracted
◌_" centralized
mid-centralized
◌_r raised
◌_l lowered

The articulations that do not have a corresponding feature name are recorded using the features of their new location in the consonant or vowel charts, not using the features of the base phoneme.

Phonation

Feature Symbol Name
brv ◌_t breathy voice
slv ◌_0 slack voice
stv ◌_v stiff voice
crv ◌_k creaky voice
glc ?_◌ glottal closure

The IPA _0 diacritic is also used to fill the vls spaces in the IPA consonant charts. Thus, when _0 is used with a vcd consonant that does not have an equivalent vls consonant, the resulting consonant is vls, not slv.

Rounding and Labialization

Feature Symbol Name
ptr ◌_w protruded
cmp compressed

The degree of rounding/labialization can be specified using the following symbols:

Feature Symbol Name
mrd ◌_O more rounded
lrd ◌_c less rounded

Syllabicity

Feature Symbol Name
syl ◌= syllabic
nsy ◌_^ non-syllabic

Consonant Release

Feature Symbol Name
asp ◌_h aspirated
nrs ◌_n nasal release
lrs ◌_l lateral release
unx ◌_} no audible release (unexploded)

Co-articulation

Feature Symbol Name
pzd ◌_j, ◌; palatalized
vzd ◌_G, ◌_e velarized
fzd ◌_?\, ◌_e pharyngealized
nzd ◌~, ◌_~ nasalized
rzd ◌` rhoticized
  1. CXS does not support using ' for palatalisation as it conflicts with the primary stress symbol. The ; symbol is CXS specific.

Tongue Root

The tongue root position can be specified using the following features:

Feature Symbol Name
atr ◌_A advanced tongue root
rtr ◌_q retracted tongue root

Suprasegmentals

Stress

Symbol Name
'◌, "◌ primary stress
"◌, ,◌, %◌ secondary stress
  1. The " primary and % secondary stress markers are from X-SAMPA. The other symbols are CXS specific.

Length

Feature Symbol Name
est ◌_X extra short
hlg ◌:\ half-long
lng ◌: long
elg ◌:: extra long
  1. The :: symbol for elg is not listed in X-SAMPA, but is derived from the transcription for lng.

Rhythm

Symbol Name
◌-\◌ linking (no break)

Tones

Symbol Name
◌_T extra high tone
◌_H high tone
◌_M mid tone
◌_L low tone
◌_B extra low tone
!◌ downstep
^◌ upstep

X-SAMPA additionally defines various symbols for contour tones that can be defined from the composite tone marks.

Symbol Composite Name
◌_R ◌_B_T rising contour
◌_F ◌_T_B falling contour
◌_R_F ◌_M_H_M rising-falling contour

Intonation

Symbol Name
<R> global rise
<F> global fall
