Speech & Audio AI Evaluation Specialist (International Voice)

We are looking for exceptional Speech & Audio AI Evaluation Specialists with genuine in-house Global Capability Centre (GCC) / Captive international

voice experience to evaluate state-of-the-art Speech-to-Speech (S2S), Text-to-Speech (TTS), and real-time conversational voice agents. Unlike traditional

transcription or BPO roles, this specialist position demands a highly trained auditory ear to evaluate prosody, cadence, phonetic accuracy, emotional

steering, and paralinguistic nuance across global English dialects. Candidates must possess C2level near-native fluency to execute rigorous human

preference and synchronization benchmarks.

KEY RESPONSIBILITIES & CORE WORKFLOWS

• S2S & TTS Naturalness Scoring: Evaluate live Speech-to-Speech and neural Text-to-Speech outputs across intelligibility, rhythm, and conversational

cadence.

• Paralinguistic & Emotion Steering Evaluation: Benchmark how effectively models express nuanced vocal attributes including empathy, hesitation,

tone inflection, irony, and situational urgency.

• Pairwise Audio Preference Ratings: Conduct blinded, head-to-head auditory preference evaluations between candidate audio completions, providing

detailed perceptual rationales.

• Multi-Modal data validations: Verify multi-modal synchronization, lip-sync alignment, and acoustic scene consistency for video dubbing and avatar

driven speech models.

• Accent & Dialect Calibration: Apply standardized rubric metrics uniformly across North American, British, Australian, and international English

accents without regional bias.

• Defensible Auditory Documentation: Document timestamped acoustic anomalies, unnatural vocal artifacts, metallic distortion, and hallucinated

phonetic segments
