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.

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.
\v can also be used for the labio-dental approximant P like in X-SAMPA.
!\` is specific to CXS. It is not listed in the IPA chart either.

i\ is in common usage in the conlang mailing list, but the X-SAMPA 1
transcription is also supported.
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.
I\ and U\ are not listed in the IPA chart.

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.
| 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.
