Brazilian Portuguese AI Audio, Text & Comment Reviewer

I am looking for a native Brazilian Portuguese speaker to help with a YouTube storytelling / animation channel. This is a fixed-price first-month trial project. If the work goes well, this can become ongoing monthly work. As the channel grows, the role may expand and the monthly rate may increase. The content is cinematic storytelling / thriller-style YouTube content. The videos will be created in English first and then adapted into Brazilian Portuguese using AI audio and translated text. I need a native Brazilian Portuguese speaker to make sure the final version sounds natural, correct, emotional, and appropriate for viewers in Brazil. Monthly trial scope: Review 2 AI-generated Brazilian Portuguese audio files per month Each audio file will usually be around 7–10 minutes long. For each audio, I need you to check: Pronunciation Fluency Naturalness Emotional tone Awkward AI-sounding phrases Incorrect meaning Words or sentences that Brazilian Portuguese speakers would not naturally say Any parts where the voice sounds robotic, too formal, confusing, flat, or unnatural Whether the dialogue feels right for thriller / drama / cinematic storytelling You do not need to re-record the audio. This is an audio review role, not a voiceover role. Review text for those 2 videos For each video, I may need help reviewing or improving: YouTube video title YouTube description Thumbnail text Short pinned comment Important translated phrases The goal is not word-for-word translation. The goal is natural, clickable, respectful, Brazilian Portuguese text that fits YouTube and the story. I do not want text that sounds like Google Translate or European Portuguese. I need text that feels natural to viewers in Brazil. Weekly comment reply support Once per week, we will spend around 15 minutes reviewing viewer comments. I will not provide login access to YouTube, Instagram, Gmail, or any channel account. The process will be: I will show or share the viewer comments You will suggest natural replies in Brazilian Portuguese You will write the replies in Upwork chat or during our call/chat I will personally copy, paste, and post the replies myself This comment support is limited to about 15 minutes per week during the trial month. If the channel grows and comments increase, we can discuss a higher monthly rate later. What is NOT included in this job: No voiceover recording No full script translation from scratch unless separately agreed No video editing No thumbnail design No YouTube, Instagram, Gmail, or channel login access No unlimited revisions No daily availability required No posting directly to the channel Budget: $40 fixed price for the first monthly trial package. This includes: 2 AI audio reviews Text review for those 2 videos Weekly comment reply help, around 15 minutes per week One round of reasonable corrections or clarifications This is a first-month trial. If the collaboration is good and the channel grows, I would like to continue monthly and may increase the monthly rate as the workload grows.
