Update 3.2.0 – AI Text to Speech – New Voices, Color Customizations, Better Performance, and More

Version 3.2.0 of our AI Text-to-Speech plugin is now availabble!

This update brings fresh new voices, a polished admin experience, extra player customisation, and a range of under-the-hood improvements to make audio generation smoother and more reliable than ever.

Three New Voices: Marin, Cedar, and Verse

We’ve added three brand-new voices from OpenAI: Marin, Cedar, and Verse.

Whether you’re after something crisp and authoritative, warm and conversational, or something with a little more flair, these additions give you even more ways to match the perfect voice to your content.

Customise Your Audio Player Colors

PRO users can now fully customise the look of the audio player to match their brand.

The new accent color and background color settings let you tweak the player’s appearance to fit seamlessly into your site design – no more one-size-fits-all styling.

New Admin Design

We’ve given the plugin’s admin pages a complete redesign.

The new layout is cleaner and more intuitive, and a brand-new header bar has been added across all plugin pages, giving you quick access to navigate between the Generator, TTS Files, Logs, and Settings pages in a single click.

Custom Voice Style Instructions: Now Always Visible

Previously tucked away, the Custom Voice Style Instructions field is now always visible directly on the post editor page.

This means you can fine-tune the tone and style of each post’s audio without needing to dig through options.

Performance Improvements for Larger Posts

Generating audio for long-form content is now faster and leaner.

We’ve reduced memory usage and database overhead during audio generation for larger posts, helping the process run more efficiently on all types of hosting environments.
