About AI Training Work

AI training is the human side of building artificial intelligence. People review model outputs, evaluate speech and language, annotate data, and provide structured feedback so AI systems can learn from accurate, nuanced examples.

• Work directly with cutting-edge AI training projects
• Use your language expertise to shape how AI systems understand and produce speech
• Many projects offer flexible, part-time schedules

The Role

OpenTrain is seeking a Thai Audio Language Evaluator to support AI training work focused on Thai speech. You will listen to Thai audio clips and assess speaker or model speech outputs using established project rubrics. Prior AI training experience is not required; strong real-world knowledge of Thai audio language is the most important qualification.

• Position type: Part-time contractor
• Time requirement: 20+ hours per week
• Work location: Worldwide and fully remote
• Pay: $30–$65 USD per hour
• Languages: Native-level Thai and at least B2 English

What You'll Do

You will complete repeated audio review tasks accurately and maintain consistent quality across evaluations. Your assessments and written explanations will help project teams understand how AI-generated or recorded Thai speech performs in real-world language use.

• Listen to Thai audio clips and evaluate nativeness, fluency, pronunciation, intonation, and linguistic authenticity
• Evaluate model outputs and apply project rubrics consistently
• Record concise, evidence-based feedback in English
• Explain the linguistic reasoning behind each assessment
• Identify and clarify content ambiguities with project coordinators
• Contribute insights that can improve AI model performance
• Maintain accuracy and consistency across assigned audio evaluations

Requirements

This entry-level opportunity is suited to candidates with strong Thai language expertise and the ability to make careful, nuanced judgments about spoken language. Relevant professional, academic, or language experience is valuable, and prior AI training experience is not required.

• Native-level command of spoken and written Thai
• Ability to identify natural versus non-native Thai phrasing
• Ability to evaluate Thai pronunciation, intonation, fluency, and linguistic authenticity in audio
• At least B2 English proficiency for precise written and verbal communication
• Strong attention to detail and the ability to articulate nuanced language differences
• Ability to follow detailed instructions, apply rubrics consistently, and work independently on remote contractor tasks
• Experience or foundational knowledge in phonetics, linguistics, voice work, audio analysis, transcription, music or audio engineering, media, communications, or teaching is valued

Who Should Apply

Apply if you are a Thai speaker who can distinguish subtle differences in pronunciation, fluency, intonation, and authenticity, then explain those judgments clearly in English. This role may suit language specialists, educators, voice professionals, transcriptionists, audio experts, and others with relevant Thai speech evaluation knowledge.

• Thai language professionals and educators
• Candidates with phonetics, linguistics, or transcription knowledge
• Voice, media, communications, and audio professionals
• Detail-oriented contributors interested in shaping AI speech systems
