""" Generate a new mapping from existing mappings in the g2p system.
This command has different modes of operation.
Standard mode:
g2p generate-mapping [--dummy|--ipa] IN_LANG [OUT_LANG]
For specified IN_LANG, generate a mapping from IN_LANG-ipa to eng-ipa,
or from IN_LANG-ipa to a dummy minimalist phone inventory. This assumes
the mapping IN_LANG -> IN_LANG-ipa exists and creates a mapping from its
output inventory.
To generate a mapping from IN_LANG-ipa to eng-ipa from a mapping
following a different patterns, e.g., from crl-equiv -> crl-ipa, specify
both IN_LANG (crl-equiv in this example) and OUT_LANG (crl-ipa in this
example).
\b
Sample usage:
Generate Algonquin IPA to English IPA from alq -> alq-ipa:
g2p generate-mapping --ipa alq
Generate Mohawk IPA to English IPA from moh-equiv -> moh-ipa:
g2p generate-mapping --ipa moh-equiv moh-ipa
Generate Michif IPA to English IPA from the union of crg-dv -> crg-ipa
and crg-tmd -> crg-ipa:
g2p generate-mapping --ipa --merge crg-dv:crg-tmd crg-ipa
List the dummy inventory used by --dummy:
g2p generate-mapping --list-dummy
From/to IPA mode:
\b
g2p generate-mapping --from FROM_L1 --to TO_L1
g2p generate-mapping --from FROM_L1:FROM_L2:... --to TO_L1:TO_L2:...
Generate an IPA mapping from the union of FROM_L1-ipa, FROM-L2-ipa, etc to
the union of TO_L1-ipa, TO-L2-ipa, etc. One or more from/to language
code(s) can be specified in colon- or comma-separated lists. Note, by default
we use Panphon's weighted_feature_edit_distance, but you can change this with
the --distance argument
\b
Sample usage:
Generate a mapping from kwk-ipa to moh-ipa based on all mappings into
kwk-ipa and moh-ipa:
g2p generate-mapping --from kwk --to moh
Generate a mapping from eng-ipa to crg-ipa based only on crg-dv -> crg-ipa:
g2p generate-mapping --from eng --to crg-dv_to_crg-ipa
Generate a mapping from kwk-ipa to moh-ipa+crg-ipa+eng-ipa based on
all mappings into kwk-ipa (from side) and the union of all mappings
into moh-ipa and crg-ipa plus eng-ipa_to_eng-arpabet (to side):
g2p generate-mapping --from kwk --to moh:crg:eng
Full syntax for specifying FROM_Ln and TO_Ln:
\b
lang (i.e., 3-letter code):
- If there is only one mapping into lang-ipa, "lang" refers to the
output of that mapping, e.g., "fra" means "fra_to_fra-ipa[out]".
- If there are several mappings into lang-ipa, "lang" refers to the
union of the outputs of those mappings, e.g., "moh" means the union
of "moh-equiv_to_moh-ipa[out]" and "moh-festival_to_moh-ipa[out]".
- It is an error if there are no mappings into lang-ipa.
- Only mappings from non-IPA to IPA are considered (i.e., IPA-to-IPA
mappings created by this command will not be included: use the
longer syntax below if you want to use them).
- Special case: "eng" refers to "eng-ipa_to_eng-arpabet[in]".
\b
in-lang_to_out-lang[[in]|[out]]:
- This expanded syntax is used to avoid the union when it is not
desired, e.g., "moh-equiv_to_moh-ipa" refers only to
"moh-equiv_to_moh-ipa,out" rather than the union "moh" represents.
- If out-lang is IPA, the output inventory is used; else if in-lang
is IPA, the input inventory is used; it is an error if neither
language is IPA.
- Specify "[in]" or "[out]" to override the above default.
- "_to_" is the joiner used to specify "the mapping from 'in-lang' to
'out-lang'" in the g2p network, regardless of the name of the file
it is stored in.
If you just modified or created the mappings from which the new mapping is
to be generated, don't forget to call "g2p update" first, so that "g2p
generate-mapping" can see the latest version.
Call "g2p update" again after calling "g2p generate-mapping" to compile
the newly generated mapping and make it available.
Note: exactly one of --ipa, --dummy, --from/--to, or --list-dummy is
required.
You can list available mappings with "g2p doctor --list-ipa", or by
visiting http://g2p-studio.herokuapp.com/api/v1/langs .
