Description

Instantly transform your text into high-quality, professional-grade audio content directly within your WordPress dashboard.

The Brand Voice Generator plugin leverages cutting-edge AI Text-to-Speech technology (Google Gemini 2.5 Flash) to create natural, lifelike voiceovers for your blog posts, landing pages, and educational content. Simply type or paste your text, select a voice, and generate.

It is built with a secure server-side proxy to protect your API keys and ensures strict access control for your team.

  • Fine-Grained Audio Controls: Adjust the voice with native API parameters for Speed (speakingRate) and Pitch (pitch).

  • Instant Playback & Download: Generate the audio, preview it immediately, and download the final .wav file instantly.

Do I need my own API Key?

Yes. This plugin provides the interface and controls, but requires a valid API Key from a compatible Text-to-Speech service (Google Cloud Gemini) to perform the actual audio generation.

How does the “Daily Limit” in the Pro version work?

The Daily Limit is a Pro feature that helps you manage your API costs. It is set per WordPress user role (e.g., Subscriber, Author). Once a user in that role reaches their limit of successful generations for the current day, they are blocked from generating new audio until the next day.

What is the Data Scrubber?

The Data Scrubber is a Pro feature that helps manage your server storage. Since Pro archives every generated audio file, the scrubber runs daily to delete files older than your set retention period (e.g., 90 days).

What happens if I use the Free version and then upgrade to Pro?

When you activate the Pro license, all Pro features (Role Presets, Media Library Save, History, SSML Quick Effects) will instantly unlock without losing any settings.
