I have a series of corporate-training modules that need to be voiced in both Mandarin and Cantonese.

A treated, quiet studio environment is mandatory; I expect clean, noise-free recordings delivered in industry-standard WAV and MP3 forma...

I have an ongoing slate of documentary films—each running well over an hour—that need to be heard in polished, idiomatic English. Your task begins with translating or adapting the original script so every nuance, tone shift, and cultural reference lands naturally for an English-speaking audience. From there, you’ll record the voiceover, matching the timing of the source audio so it slips seamlessly into the existing video edit. What I care about most is authenticity: clean pronunciation, steady pacing, and an expressive delivery that carries the weight and mood of the footage. Once the read is down, you’ll handle the usual post-production steps—noise reduction, leveling, and a final linguistic pass—to deliver a broadcast-ready WAV or high-quality MP3. ...
