Vocal Audio Specialist - Freelance AI Trainer Project

About this role

Project Overview We are sourcing independent Vocal Audio Specialists to provide their expertise for an AI audio model training project. As AI models increasingly generate and interpret human musicality and vocal nuances, their accuracy relies entirely on robust, high-fidelity training data. The objective of this project is to autonomously record clean, professional-grade audio detailing human vocal pitch changes by performing consistent, highly controlled humming exercises. Project Deliverables & Scope Operate autonomously to generate precise audio assets and structured training data. Expected deliverables include: Vocal Recording & Pitch Execution: Recording clean, pitch-stable humming takes with dynamic control (e.g., humming softly without disappearing or louder without distorting), while strictly following tonal prompts (e.g., "hum a major 3rd," "stay in key"). Rhythmic & Melodic Consistency: Demonstrating a solid "internal metronome" to follow beats and executing highly repeatable tasks, such as humming the exact same melody multiple times with minimal variation. Audio Engineering & Quality Control: Applying professional recording competence—including proper mic proximity, gain/input controls, and gain staging—to ensure distortion-free, high-fidelity audio capture within a controlled environment. Strict Instruction Adherence: Accurately executing highly specific vocal directions (e.g., "flat tone, no vibrato") to generate clean, reliable, and standardized data for model training. Required Expertise To successfully fulfill the deliverables of this project, Contractors must possess strong musical literacy paired with reliable home recording capabilities. Core skillset includes: 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.
