Nasal Vowels Language Checker

Independently documented contrastive nasal vowels, not merely nasalization before nasal consonants. Exact independently verified context/edition key, not live or embedded reference data. Caller establishes language, dialect, method and reference context; no automatic identity or universal language-wide claim.

Description

Nasal vowels may be contrastive categories or context-conditioned realizations.

Nasal vowels may be contrastive categories or context-conditioned realizations.^[1]

A reference needs to distinguish those analyses before attributing an inventory feature to a language. The tool retrieves your supplied source-specific notice for one exact key; it contains no built-in or live reference database.

When to use Nasal Vowels Language Checker

Use this tool to calculate or review the supplied observations under the stated rules. Specify the language variety, analysis, source edition and population or inventory definition.

How to use Nasal Vowels Language Checker and understand its results

Specify the language variety, analysis, source edition and population or inventory definition.
Enter callerVerifiedNasalVowelKeys, callerVerifiedNasalVowelNotices, queryNasalVowelKey, using the field meanings and rules below, then run the tool.
Read matchedCallerNotice, using the output meanings and calculation rules below. Confirm that the exact matched record is the one whose source and context apply.
Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.

Input field	Meaning	Value type	Requirement
callerVerifiedNasalVowelKeys	Caller verified nasal vowel keys	list of string	Required
callerVerifiedNasalVowelNotices	Caller verified nasal vowel notices	list of string	Required
queryNasalVowelKey	Query nasal vowel key; use the exact reference token or coordinate domain stated below	string	Required

Supply nonempty aligned unique nonblank context keys and nonblank notices, then query one exact existing key. Matching is case-sensitive without trimming or normalization. Return its original notice unchanged; unknown keys fail. No data is fetched or independently verified.

notice=notices[indexOf(keys,exactQuery)]

Use the matching field units and the exact boundary, ordering and reference rules above.

Output field	Meaning	Value type
matchedCallerNotice	Matched caller notice	string

Limitations and assumptions

The language variety, analytical definitions and reference scope are supplied by the caller. No corpus, speech or complete/current linguistic registry is analyzed automatically. Reference records and their claimed verification are supplied by the caller; the tool does not retrieve or verify them.

Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.
