Sibillo Audio – Text to Speech, AI Voices & Podcast Feeds
Sibillo Audio turns your WordPress posts into natural-sounding audio, so visitors can listen to your articles instead of reading them. Speech is generated in the cloud by the external WPVoicer.com text-to-speech service: an administrator explicitly selects a post and requests generation, and the completed MP3 is downloaded to the site's WordPress Media Library.
The plugin also provides local features that remain available when the WPVoicer.com account is disconnected:
- Audio Library for previously generated MP3 files
- Local audio playback and play counts
- Shortcode and page-builder audio fields
- Podcast management and locally generated RSS feeds
Features
- Generate speech from WordPress post content
- Select languages and standard or premium cloud voices
- Upload a voice sample when voice cloning is enabled for the connected service account
- Store generated MP3 files in the WordPress Media Library
- Embed audio with
[sibillo_audio_audio] - Use audio fields with Elementor, Bricks, and Breakdance
- Build podcast feeds from posts that already contain generated audio
- Manage local audio and podcast feeds while disconnected
External service and pricing
Cloud generation requires a WPVoicer.com account and available service credits or an eligible service plan. Introductory credits may be included with a new service account. Additional credits and cloud capabilities are offered by WPVoicer.com.
The WordPress plugin code is free and fully available under the GPL. Payment applies only to cloud processing and service capacity supplied by WPVoicer.com. The plugin does not download premium code or executable updates from the service. Existing local MP3 files, playback, Audio Library and podcast features are not removed when cloud generation is unavailable.
How it works
- Install and activate Sibillo Audio.
- Open Sibillo Audio > Connection and connect a WPVoicer.com account.
- Configure a voice under Voice Settings.
- Edit a post and explicitly request audio generation.
- The post content and selected settings are sent to WPVoicer.com.
- The generated MP3 is downloaded to the site's Media Library.
Third Party Services
This plugin connects to the external WPVoicer.com Software-as-a-Service platform. The service performs text-to-speech generation, voice previews, speaker-list retrieval, account and usage requests, and custom voice processing.
The plugin does not contact WPVoicer.com merely because it is installed, activated, deactivated, or loaded. Requests are made when an administrator performs an action that requires the service, including registration, login, loading service voice data, previewing a voice, checking account usage, uploading or deleting a custom voice sample, generating audio, polling a requested job, downloading generated audio, or opening an authenticated dashboard link.
Data sent to WPVoicer.com
Depending on the requested action, the plugin may send:
- Account credentials or connection data entered by the administrator
- Site URL and site identifier used to associate the connection
- Selected post ID, title and text for requested speech generation
- Language, voice, provider, speed and generation parameters
- A custom voice sample when the administrator explicitly uploads one
- Job identifiers used to retrieve generation status and audio
- Plugin, WordPress and PHP versions as part of authenticated service requests
Local data
- Generated MP3 files are downloaded to the site's Media Library.
- Audio references, settings and play counts are stored in WordPress options or post metadata.
- Podcast RSS feeds are generated locally from WordPress posts and local audio.
- Existing local audio and podcast functionality remains available after disconnection.
