Question: I'm looking for a cost-effective Text-to-Speech API that can convert text into high-quality audio for my content platform.

If you're on a budget and need a Text-to-Speech API, Unreal Speech could be a good option. It's got good speech synthesis at a lower price than many big companies. It's got six voices and supports common file formats, and you can adjust the speaking rate and pitch. It's got a free tier with 625M characters per month, and custom tiers for more usage, and is good for content consumption, customer service, education and gaming.

DeepZen is also an option, particularly if you want high-quality audio content with human-sounding emotion and intonation. It's got flexible pricing and integrates with Unreal Engine and Unity, so game developers should be interested. DeepZen makes it easier to create audio content, speeding up the process and making it more accessible.

BeyondWords offers an audio content management system with more than 550 AI voices in 140 language locales. It's got advanced voice technology and a variety of customization options, including voice cloning and automatic SSML normalization. Its pricing tiers include a free tier, so it's good for increasing reach and engagement in a variety of content types.
