(Speech and Voice Characterisation)

We are looking to find a skilled Voice Identity and Timbre Annotation Specialist to join our growing team.

You will analyse and label timbre and identity-related characteristics of voices. These annotations support models that differentiate, match and cluster voices based on their acoustic qualities.

Responsibilities:

• Listen to speaker samples and describe timbre attributes using a structured vocabulary such as bright, dark, nasal, breathy, rough, smooth or metallic

• Annotate perceived age range, gender presentation and speaking style where allowed by guidelines

• Identify recurring spectral or textural features that make a voice distinctive and capture them in notes

• Assess consistency across multiple samples from the same speaker and flag cases affected by recording conditions

• Provide structured identity tags for downstream retrieval and clustering tasks

Requirements:

• Strong ear for subtle differences in voice texture and quality

• Ability to focus on sonic traits independently of spoken content

• Comfort with repeated listening and comparative evaluation

Background:

• Audio engineering, vocal production, casting, music production, radio or podcast work

• Experience describing voice qualities for creative, technical or casting decisions

Sample Test Task:

• Given six voice samples, describe each voice using timbre descriptors, group similar voices together and briefly justify the grouping.

Application Requirements:

• Short note describing how you would characterise your own voice timbre

• Optional examples of previous work involving voice selection or description

• Completed test task

Compensation

• Per speaker profile or per collection of samples, depending on dataset design.
