Vocal Audio Specialist - Freelance AI Trainer Project

About the Role

We are sourcing independent Vocal Audio Specialists to provide expertise for an AI audio model training project. The objective is to autonomously record clean, professional-grade audio detailing human vocal pitch changes by performing consistent, highly controlled humming exercises for model training data.

Responsibilities

• Operate autonomously to generate precise audio assets and structured training data.
• Vocal Recording & Pitch Execution: Record clean, pitch-stable humming takes with dynamic control (e.g., humming softly without disappearing or louder without distorting) while following tonal prompts (e.g., "hum a major 3rd," "stay in key").
• Rhythmic & Melodic Consistency: Demonstrate a solid internal metronome to follow beats and execute highly repeatable tasks, such as humming the exact same melody multiple times with minimal variation.
• Audio Engineering & Quality Control: Apply professional recording competence, including proper mic proximity, gain/input controls, and gain staging, to ensure distortion-free, high-fidelity audio capture in a controlled environment.
• Strict Instruction Adherence: Accurately execute highly specific vocal directions (e.g., "flat tone, no vibrato") to generate clean, reliable, and standardized data for model training.

Qualifications

• Demonstrable musical literacy and performance history (e.g., choir, band, a cappella, live gigs, audio engineering, or music production) with a calm, controlled voice and a highly trained ear for pitch stability.
• Hands-on experience in Voice Over (VO) work, studio recording, or prior AI audio training projects; candidates new to recording workflows will not meet the quality threshold.
• Strong technical recording competence, including deep understanding of gain staging, microphone technique, and operation of recording equipment.
• Meticulous, detail-oriented approach to following instructions and maintaining rhythmic and tonal consistency across multiple recorded takes.
• Required asset: a controlled, quiet home recording environment capable of capturing clean audio free from background noise, clipping, or room echo.

Benefits

• Pay range: $6 to $65 per hour (exact rate determined after evaluating experience, expertise, and geographic location; final offer may vary).
• Engagement is freelance / independent contractor; contractors must supply a secure computer, professional recording equipment, and high-speed internet.
• Company-sponsored benefits such as health insurance and PTO do not apply.

Additional Information

• Engagement Type: Freelance / Independent Contractor.
• Workplace Type: Remote.
