NarrationBox sells monthly word allowances with a large voice catalog. AudioPod narrates on your subscription credits or, with no plan, at $19 per finished hour, quoted from your manuscript — and exports ACX-spec MP3s plus an M4B with chapter markers. Neither lets you submit AI narration straight to ACX.

AudioPod's Audiobook Studio takes a PDF, EPUB, DOCX or pasted text and narrates it paragraph by paragraph with multi-voice casting and voice cloning in 100+ languages. Subscribers pay from credits; without a plan it is $19 per finished hour, or $79 with a person checking the finished book.
NarrationBox is an AI narration tool. Its pricing page lists monthly plans measured in text-to-speech words (the free plan has 1,000 words with watermarked, low-quality export), voice clones per plan, word top-ups, 1,500+ voices across 80+ languages and accents, and a done-for-you audiobook service with chapter exports.
