About Turing
Turing is one of the world's fastest-growing AI companies, partnering with leading AI labs to advance frontier model capabilities in reasoning, coding, multilinguality, and more. We build real-world AI systems that solve mission-critical challenges for global organizations.
Role Overview
You will review and validate AI-generated transcriptions and diarization outputs for multi-channel audio recordings, ensuring high accuracy across diverse conversational dynamics, speakers, and contexts.
Day-to-Day Responsibilities
- Review AI-generated transcriptions and diarization outputs against strict low word-error-rate (WER) targets.
- Validate that transcripts accurately capture spontaneous speech, including overlaps, interruptions, false starts, and disfluencies.
- Assess the precision of turn-level and word-level timestamps and speaker identification in complex, overlapping dialogue.
- Read and validate JSON-formatted outputs for accurate metadata tagging, diarization alignment, and timestamp logic.
- Identify transcription, segmentation, and alignment errors and determine whether AI output meets acceptance thresholds.
Requirements
- Fluent or native proficiency in Spanish (Latam or Spain).
- Exceptional ear for audio fidelity — able to detect background noise, channel bleed, or clipping.
- Meticulous attention to detail for word-level timestamps, diarization accuracy, and verbatim transcription.
- Ability to evaluate AI transcription quality and identify recognition, segmentation, and speaker attribution errors.
Preferred Qualifications
- Linguists / Phonetics Experts: Deep understanding of natural, unnormalized speech patterns and conversational dynamics.
- Language Teachers: Native-level mastery of Spanish with the ability to evaluate transcript fidelity without normalization or grammar correction.
- Professional Transcriptionists / Speech Data QA Specialists: Experience reviewing ASR outputs, validating timestamps, and assessing transcription quality against strict accuracy targets.
Perks of Freelancing With Turing
- Fully remote, flexible work environment.
- Opportunity to contribute to cutting-edge AI projects with leading LLM companies.
- Potential for contract extension based on performance and project needs.
