I’m assembling a small team of native-level Portuguese speakers to help me enrich an AI speech database. Your contribution will be to capture natural-sounding audio in the form of daily conversations. Feel free to sit with a friend, chat to your phone, or even interview yourself—what matters is that the dialogue flows naturally in Portuguese. Topics you can focus on are entirely up to you, but I’m especially interested in recordings about current events, personal experiences, and hobbies or other interests. Each session can be as short as one minute or stretch to an hour; work whenever inspiration strikes, up to roughly five hours a day. All recording and submission happen through our dedicated mobile app, so a modern smartphone and a stable internet connection are must-haves. This is a one-month, fully remote freelance contract. You set your own schedule and complete tasks independently—perfect if you’re looking for flexible side work or a way to monetise your everyday conversations. No previous voice-over or transcription background is necessary; fluency in any Portuguese accent is all you need. Deliverables • High-quality Portuguese audio files recorded via the provided app • Natural, unscripted dialogue centred on the chosen daily-conversation topics • On-time uploads that meet basic audio clarity guidelines If you love talking and want to help shape the next generation of voice-driven technology, I’d love to have you on board.

I have extensive experience in linguistic data collection and high-fidelity voice recording for AI training, specifically targeting nuanced datasets for speech synthesis. Having recently contributed to a phoneme mapping project for a Portuguese LLM, I understand that the success of a speech database hinges on capturing natural prosody, consistent articulation, and authentic linguistic markers. As a native speaker with a professional-grade home studio, I am ready to provide the clean, high-resolution vocal samples your database requires to enhance model accuracy and natural language processing performance across all intended training cycles. To ensure production-grade consistency, I will record in a sound-treated environment using a professional cardioid condenser microphone and a dedicated DAW to eliminate noise floors and clipping. I will adhere strictly to your script while maintaining a conversational yet precise cadence, ensuring every phoneme transition is articulated clearly for seamless machine learning ingestion. My workflow includes a meticulous self-QA process to normalize levels and verify that all deliverables meet your exact sample rate and file-naming conventions, ensuring a "plug-and-play" integration for your engineering team without the need for additional post-processing or cleaning. Are you prioritizing a specific regional dialect—such as European or Brazilian Portuguese—for this phase, and do you have a preferred metadata structure for the final exports? I am happy to record a 30-second sample using your script so you can evaluate my tone and recording environment immediately. Feel free to reach out via chat to discuss the project volume or jump on a quick call if you would like to align on the technical requirements for this intake.
