Project Description

Help improve AI-generated speech, audio and video through language and content evaluation. Project tasks and eligibility vary.

What you’ll do

  • Evaluate speech for naturalness, fluency and pronunciation, and assess audio clarity, sound quality and vocal consistency.
  • Identify language errors, unnatural speech and audio issues.
  • Provide structured feedback and quality ratings using project guidelines.
  • Review audio-video synchronisation, captions and timestamps when required.

Languages and requirements

Proficiency is sought in Thai (Thailand), French (France), Vietnamese (Vietnam), Malay (Malaysia), Japanese (Japan), Korean (South Korea), Indonesian (Indonesia), Gulf Arabic, Spanish (Mexico or Spain), Portuguese (Brazil or Portugal), Tagalog (Philippines), German (Germany), Dutch (Netherlands), Polish (Poland), Swedish (Sweden), Russian (Kazakhstan) or Turkish (Turkey). English proficiency at B2 level or above is also required.

Understanding of regional pronunciation, expressions and cultural nuances is particularly valuable. Language variants and country-of-residence requirements depend on the project. Indicate your strongest language and any additional languages you speak proficiently.

Relevant experience

Experience in one or more of the following is an advantage: LLM or VLM evaluation; supervised fine-tuning, benchmarking or model response assessment; prompt-response and instruction-following evaluation; multimodal evaluation; transcription or linguistic quality review; image annotation, data labelling or content moderation; search relevance, digital content evaluation or quality assurance; or social media and gaming content.

Experience in every area is not required. A relevant degree is welcome, but candidates may also qualify by demonstrating their skills, depending on client requirements.
