Vietnamese Linguistic Specialist – NLP and Speech Technology

Position Overview

We are seeking a Vietnamese Linguistic Specialist to support NLP and speech-technology projects involving grammar development, language localization, phonetics, pronunciation resources, tokenization, text normalization, and Vietnamese language variation.

This is a technical linguistics position, not a translation-only or general annotation role. We welcome candidates from different backgrounds, including:

Linguists or language specialists with an interest in technology and some experience using Linux, Generative AI tools, or technical language workflows.

Candidates with experience in computational linguistics, NLP, language technology, speech technology, or a related technical field.

Previous professional experience with every technology listed below is not required. Candidates should, however, be comfortable learning technical concepts, following structured specifications, analyzing language patterns, and completing a practical technical assessment.

What you will do

Develop, extend, test, and localize structured language grammars for Vietnamese.

Review and adapt rule-based grammar formats such as JSGF, context-free grammars, BNF, or comparable frameworks.

Create and evaluate Vietnamese utterance patterns containing intents, entities, slots, and alternative sentence structures.

Identify issues related to grammar coverage, ambiguity, overgeneration, consistency, and scalability.

Support the development and review of Vietnamese pronunciation dictionaries and other linguistic resources.

Work with phonetic representations and grapheme-to-phoneme workflows.

Contribute to tokenization, text preprocessing, and text-normalization processes.

Analyze Vietnamese word boundaries, sentence structures, diacritics, abbreviations, slang, spelling variations, and conversational language.

Identify and document differences among Northern, Central, and Southern Vietnamese varieties.

Distinguish between formal written Vietnamese and spontaneous spoken Vietnamese.

Develop and improve linguistic guidelines, normalization rules, annotation instructions, and technical documentation.

Explain linguistic decisions, Vietnamese-specific challenges, and recommended solutions clearly.

Collaborate with linguists, NLP engineers, speech-technology specialists, project managers, and other stakeholders.

Requirements

Required Qualifications

Fluent or native-level proficiency in Vietnamese.

Professional working proficiency in English, including the ability to understand technical instructions and explain linguistic decisions in writing.

A background in linguistics, language studies, computational linguistics, NLP, language technology, speech technology, or another relevant field.

Strong knowledge of Vietnamese grammar, word boundaries, sentence structure, and diacritics.

Familiarity with Vietnamese abbreviations, slang, spelling variations, and conversational language.

Awareness of Northern, Central, and Southern Vietnamese language variation.

Ability to distinguish between formal written Vietnamese and spontaneous spoken Vietnamese.

Some familiarity with Linux environments and command-line tools.

Familiarity with Generative AI tools or language-model applications.

Strong analytical, problem-solving, and technical-writing skills.

Ability to learn new technical concepts and work with structured grammar formats.

Ability to work independently and follow detailed technical specifications consistently.

Formal training in computational linguistics is not mandatory. Linguists and language specialists with the required Vietnamese expertise who are comfortable working with Linux, Generative AI, and structured technical tasks are encouraged to apply.

Preferred Qualifications

Experience with JSGF, context-free grammars, BNF, or another grammar-based language framework.

Familiarity with NLP concepts such as intents, entities, slots, utterance patterns, tokenization, and normalization.

Experience with phonetics, pronunciation dictionaries, or grapheme-to-phoneme conversion.

Experience in ASR, NLU, conversational AI, TTS, or another speech-technology area.

Familiarity with regular expressions, finite-state methods, or rule-based text processing.

Experience developing linguistic datasets, annotation guidelines, normalization rules, or language-generation resources.

Basic programming or scripting experience, preferably in Python.

Experience evaluating linguistic resources for coverage, ambiguity, accuracy, consistency, and scalability.

Conditions

Technical Assessment

As the first step in the recruitment process, selected candidates will be invited to complete a brief technical assessment designed to evaluate their ability to:

Interpret and extend a structured language grammar.

Represent new intents and entities within the grammar.

Localize grammar rules and example utterances into Vietnamese.

Identify Vietnamese-specific linguistic challenges.

Explain how the proposed approach could be expanded to support additional utterances and linguistic variation.

The assessment is intended to evaluate practical reasoning and learning ability. Previous professional experience with the exact grammar format used in the assessment is not required.

Compensation

Compensation will be negotiated based on the candidate’s qualifications, linguistic expertise, technical skills, and relevant professional experience.

If you have strong Vietnamese linguistic knowledge and are comfortable working with language technology, Linux, and Generative AI tools, we invite you to apply.

We appreciate all applicants' interest. We will contact only candidates selected for the next stage of the recruitment process.
