Audio Engineer (Speech / TTS Audio Specialist) – Brazilian Portuguese

$20–30/hr

rate as listed

Workload: ~15h/week
Engagement: Project-based
Location: Worldwide
Field: Languages

Edit and quality-check Brazilian Portuguese voice recordings for speech and text-to-speech training datasets. The work combines audio restoration, technical compliance checks, linguistic judgment and consistent batch processing.

The work

Day to day, you would edit Brazilian Portuguese speech recordings for TTS and speech AI datasets. Tasks include trimming silence, reducing breaths, removing clicks, controlling sibilance and noise, balancing levels, and checking for clipping, distortion and other artifacts across large batches.

Quality judgment

The role also requires linguistic evaluation, not just signal cleanup. Native or near-native Brazilian Portuguese fluency is required so you can assess pronunciation, fluency and naturalness while distinguishing genuine defects from acceptable speech variation. Edits must preserve intelligibility and natural vocal character while meeting the technical specifications supplied for an ML training pipeline.

What the screen is likely to assess

Expect questions about your speech-editing background, restoration tools such as iZotope RX or Pro Tools, and methods for maintaining consistency in structured, high-volume workflows. The screen may also test how you diagnose defects, avoid introducing processing artifacts, document ambiguous cases and evaluate human recordings against TTS requirements. Experience with TTS vendors, voice AI, dataset annotation, audio QA or Brazilian Portuguese voice talent is preferred rather than stated as required.

Practical details

The listing does not specify whether the engagement is remote or asynchronous, and it does not state typical weekly hours or scheduling requirements. Be prepared to give a concrete account of your availability and production capacity. Pay band: $20–30/hr

Interview prep — 10 questions

Matched to what this platform's screening actually measures. Answer each out loud in 60–90 seconds: claim → concrete example → implication.

What it tests: This tests whether your claimed experience is tied to a verifiable speech project rather than general music production or unspecific audio work.
A strong answer: Give the project context, approximate batch size, source condition, tools used, exact editing and QA responsibilities, and the delivery specifications you worked against. Clarify which decisions you owned and how quality was reviewed.
Where people lose it: Candidates lose points by discussing mixing music, podcasts or general studio work without showing responsibility for structured Brazilian Portuguese speech assets.
