AI/LLM Speech & Audio AI Evaluation Specialist (Int. Voice)

About the Opportunity
A fast-growing AI innovation lab focused on next-gen voice and speech intelligence, we build and evaluate cutting-edge Large Language Models (LLMs) for real-world conversational AI applications. Our work spans multilingual voice agents, prosody modeling, and context-aware synthesis—serving global clients across fintech, healthcare, and telco sectors. We move fast, validate rigorously, and ship voice experiences that sound human, behave intelligently, and scale reliably.

Role & Responsibilities

• Evaluate and benchmark LLM-driven speech outputs across fluency, naturalness, emotional tone, and contextual accuracy using standardized metrics and custom rubrics.


• Design and run A/B tests for voice models across accents, registers, and cultural contexts to improve perceived quality and user trust.


• Annotate, transcribe, and label voice datasets for training and evaluation—focusing on turn-taking, intent alignment, and paralinguistic features.


• Collaborate with ML engineers to translate evaluation insights into fine-tuning signals and data augmentation strategies.


• Document voice quality trends, failure modes, and improvement pathways in structured reports for cross-functional review.


• Stay current with research in speech AI, prosody, and LLM evaluation—applying new methods like pairwise preference ranking or automated metrics (e.g., MOS, WER, CER).
