đź“‹ Description
- • Lilt Production is seeking a highly skilled and experienced Voice Coach specializing in Brazilian Portuguese to join our innovative team. This is a unique opportunity to contribute to the advancement of AI technology by ensuring the quality and authenticity of voice data used for training artificial intelligence models. As a Voice Coach, you will play a pivotal role in guiding voice talents to deliver exceptional performances that meet stringent quality standards, directly impacting the effectiveness and naturalness of AI-driven communication tools.
- • In this remote, freelance contractor position, you will be responsible for overseeing and directing voice recording sessions. Your primary objective will be to ensure that the voice talents produce audio that is not only technically sound but also emotionally resonant and linguistically accurate. This involves providing real-time feedback and guidance to talent, acting as a critical "second ear" to identify and rectify any inconsistencies or deviations from the project's requirements.
- • Your expertise will be crucial in maintaining a consistent quality across all recordings. This includes monitoring for subtle nuances in vocal delivery, ensuring that the emotional tone aligns with the script's intent, and verifying that the overall performance is engaging and believable. You will be tasked with ensuring a stable rhythm and tempo throughout the recordings, preventing any unnatural pauses, rushed speech, or erratic pacing that could detract from the AI's learning process.
- • Furthermore, you will meticulously control pitch and amplitude, guiding talents to maintain vocal clarity and avoid excessive fluctuations that could compromise the audio quality. This attention to detail is paramount for creating datasets that allow AI to accurately interpret and replicate human speech patterns.
- • A significant aspect of your role will involve coaching for correct diction and articulation. You will guide voice talents to pronounce words clearly and distinctly, ensuring that every syllable is intelligible. This is especially important for Brazilian Portuguese, where regional accents and specific phonetic challenges can arise. Your guidance will help standardize pronunciation, making the AI more robust and adaptable to diverse linguistic inputs.
- • You will be expected to attend recording sessions, whether conducted online or in a studio environment, for their entirety. This ongoing presence ensures immediate intervention and continuous improvement throughout the recording process. Your coaching structure and methodology should be clearly reflected in your project quotation, demonstrating a well-thought-out approach to achieving the desired outcomes.
- • The recordings are intended for AI data training, meaning the quality and accuracy of the audio are of utmost importance. The AI systems learn from these recordings, so any imperfections or inconsistencies can lead to flawed AI performance. Your role as a Voice Coach is therefore critical in building high-quality, reliable AI models that can effectively understand and generate human language.
- • Lilt is at the forefront of transforming how the world communicates through AI. Our mission is to break down language barriers and make information accessible to everyone globally. By joining Lilt, you become part of a dynamic community driven by innovation, excellence, and a shared passion for advancing human knowledge. We believe in the power of diverse perspectives and skills to deliver cutting-edge multilingual AI and human-verified services to a wide range of clients, including enterprises, governments, and AI developers.
- • This position offers the flexibility of remote work, allowing you to contribute your expertise from anywhere in Brazil. You will have the opportunity to work on diverse projects, manage your own schedule, and earn money while advancing the field of AI. We are committed to fair and prompt payment through our streamlined contractor payment system, Tipalti. Lilt fosters a supportive community where you can build your professional network and grow your career.
- • We are dedicated to a fair, inclusive, and transparent hiring process. While we may utilize AI and automated tools to assist in evaluating applications, all final hiring decisions are made by human professionals. We are committed to equal opportunity employment and value the unique contributions of every individual, regardless of their background. Your application and participation in our hiring process are subject to Lilt's Privacy Policy.
