• Analyzing and review pronunciation data, including grapheme-to-phoneme mappings, diacritization/tashkeel, and lexicons, for Arabic TTS and speech recognition systems.
• Evaluating TTS output quality in terms of pronunciation accuracy, prosody, dialect authenticity, and naturalness, with a particular focus on Saudi Arabic.
• Providing linguistic guidance and support for Arabic voice data collection and speech synthesis projects, including identifying and onboarding suitable voice talents when needed.
• Supporting the coordination and review of voice recording and editing processes to ensure linguistic accuracy and consistency.
• Supporting the onboarding and coordination of external Arabic language consultants when needed and providing guidance on linguistic requirements.
• Reviewing and providing linguistic feedback on data annotation activities and guidelines, ensuring appropriate quality standards for Arabic and Saudi dialect data.
• Collaborating closely with the Sestek TTS and AI Research teams and providing ongoing linguistic expertise throughout the project.

What you will bring:
