Charina R.

I am a bilingual Language QA Specialist and AI Tester, specializing in generative AI evaluation, proofreading, and voice testing. I bring hands-on experience testing generative AI systems, including Gemini Live. My work involves evaluating real-time conversations, assessing speech-to-text accuracy, and refining AI responses to enhance overall user experience. As a beta tester for AI chatbots, I rigorously stress-test applications, identify bugs and logical inconsistencies, and provide detailed, actionable feedback to drive product improvements. Backed by my degree in Business Administration and my upcoming plans to formally study literature, I offer over 10 years of experience writing, proofreading, and editing Spanish content, with a strong background in creative writing. I have successfully localized educational content for children by carefully reviewing grammar, phrasing, consistency, and cultural nuances, ensuring the final text feels entirely natural rather than like a literal translation. In the field of voice evaluation, I meticulously assess each audio sample individually, focusing exclusively on fluency and pronunciation, alongside naturalness and overall quality, ignoring the content of the response itself. I have collaborated with ElevenLabs to review and select AI-generated voices for Spanish educational materials, paying close attention to accents and target-audience suitability. Additionally, I provide human voiceover recordings when authentic vocal delivery is required. I am also experienced in AI safety initiatives, successfully sourcing and categorizing real-world datasuch as scam and non-scam messagingto train safer, more reliable AI models. My professional background as an Administrative Assistant further reinforces my strong organizational skills, meticulous attention to detail, and ability to manage complex tasks independently. I thrive in analytical environments where I can read, listen, test, and compare data to identify hidden issues. I am passionate about delivering clear, highly constructive feedback to help products reach their maximum potential.
