Felipe C.

Data Annotation Expert and Artificial Intelligence Educator

In recent years, linguistic data has truly transformed how the world interacts with technology, enabling more intuitive and accessible experiences through advancements in speech and language processing. I am excited about the opportunity to contribute my expertise to your team, drawing on a decade of hands-on experience in developing high-quality linguistic resources for AI-driven platforms. My name is Felipe, and I am from Brazil. For the past 15 years, I have been immersed in the field of Natural Language Processing (NLP), with a special focus since earning my Master’s degree in Linguistics, where I concentrated on Phonetics and Phonology. Throughout my career, I have collaborated with several companies, primarily dedicated to building and curating data that fuels Automated Speech Recognition (ASR) and Text-to-Speech (TTS) systems. I have actively participated in a wide range of projects, including: - 15 years of audio evaluation and recording: Conducting and supervising high-quality recordings and rigorous audio assessments to ensure the optimal performance of speech technologies. - 20 years dealing with speech analysis: Carrying out in-depth analyses of speech data for various linguistic and phonetic features. - 12 years interacting with data mining: Extracting relevant linguistic materials from large and diverse corpora. - 10 years as data annotator: Providing precise labels for phonetic, morphological, part-of-speech (POS), Universal Dependencies, and semantic properties, which serve as the foundation for training effective AI models. - Handling language issues: Addressing challenges ranging from dialectal variation to sentence structure and semantic ambiguity. Alongside my linguistic knowledge, I possess technical abilities including proficiency with regular expressions, bash scripting, and basic Python programming, allowing me to support and streamline data processing tasks. My enthusiastic passion for Natural Language Processing and Understanding drives me to remain at the forefront of current research and best practices, and fuels my commitment to high standards in every project I undertake. Beyond my core work in NLP, I have significant experience in dictionary translation projects for Portuguese, as well as other translation assignments. In addition, I have provided content writing and ghostwriting services to a wide array of industries, including wine, cybersecurity, CRM, technology, and health. My versatility as a writer and translator has enabled me to craft clear, compelling content accurately tailored to different audiences and technical requirements.
