Question: I'm looking for a text-to-speech service that can help me create high-quality audiobooks, do you know of any?

If you're looking for a premium text-to-speech service for generating audiobooks, DeepZen is worth a look. The AI-based service generates audio content with human-sounding emotion, intonation and rhythm, good for audiobooks, ads and marketing. It has tiered pricing for pro, start-up and enterprise customers, and can be used in Unreal Engine and Unity game engines, which is useful for video game developers.

Another option is Audie, an AI-based audiobook creation service that lets authors turn written books into high-quality audiobooks with natural-sounding voices. It's got an easy-to-use interface where you can pick from more than 50 different voices and fine-tune the narration. Audie is relatively inexpensive, with prices ranging from $18 to $269, so it should be within reach of many content creators.

Narration Box has a lot of features, including a block-based interface that's easy to use, a library of 700+ AI narrators, and options like context awareness and emotive styles. It supports more than 140 languages and accents, so it's good for lots of use cases besides audiobooks. The service offers a free tier and several paid tiers depending on how much you use it.
