ACX audio book voice over

I am looking for a voiceover to recreate my short e-book of 10,000 words. The book will do well with a motherly British/ Londoner accent and someone who can relate to the content which is also a guide book so just needs points of humour at some point's not monotone. The speaker will hold no rights to the book and will be required to sign a NDA. You will need to deliver the final copy to ACX format and therefore know what this is . Suggested AI tool would be elevenlabs.io as they provide a great range of voices and tones to suit the requirement of my e-book delivery of the book should take no more than 3 hours I would ask that the hired freelancer provides example of the chosen voice before completing and moving forward with the whole project ad the voice and tone is really important for the book.

Thai Voice Sentence Recording

I’m collecting a set of 300 short Thai sentences for speech-training research and I’d like a native speaker to record them directly in our mobile app. You’ll be working with a smartphone—any operating system is fine, even alternatives beyond iOS or Android—and you should be able to record in a completely quiet space so there’s no background noise on the clips. Once you accept, I’ll send login credentials, a step-by-step recording guideline, and a link to the app. The workflow is straightforward: open the script inside the app, tap to record each sentence, review the waveform for clarity, and save. The system automatically uploads every take, so there’s no post-processing required on your side. Deliverable • 300 clearly spoken Thai sentences, captured and uploaded through the app, passing the built-in silence and clipping checks. I release payment after the platform confirms that all 300 files meet the quality threshold for volume, pronunciation, and absence of background noise. If you’re a native speaker with a quiet room and a smartphone, this should take less than an hour. Feel free to apply and I’ll get you set up right away.

No extra features or fancy UI—just a basic, working example I can build on later. (i want to be able to set its instructions and guidelines however i want easily)
