PUBVOICE – AI Audio Player

PUBVOICE is an AI-powered text-to-speech (TTS) service that converts your WordPress articles into high-quality audio — automatically. Add a “listen path” to your blog so readers can consume your content during commutes, workouts, or any screen-free moment.

Free plan available — start with no credit card required.

Why Audio?

The podcast market continues to grow year after year. According to Edison Research, 47% of Americans aged 12+ listen to podcasts monthly. In Japan, audiobook usage is growing ~20% year-over-year (Yano Research Institute). AI voice synthesis quality has improved dramatically while costs have dropped — making article audio conversion practical for any publisher.

Readers want to consume content in screen-free moments: commuting, exercising, cooking. Text-only media miss these touchpoints entirely. Adding a listening experience lets your articles reach audiences during time they already have, but can’t use their eyes.

Proven Results

Deployed across 30+ media sites, PUBVOICE has delivered measurable improvements:

• 11x longer session duration — readers stay while listening
• +32% repeat visit rate — listeners come back to listen again
• +19% more page views — audio navigation drives multi-article browsing

The most surprising finding: repeat visitors shift from “arriving via search” to “coming back to listen.” The delivery channel changes the relationship quality between your content and its audience.

Not Just Read-Aloud — Intelligent Scripting

PUBVOICE doesn’t simply read your article text aloud. The AI understands article structure — headings, bullet points, tables — and automatically rewrites scripts for natural listening. This means proper pacing, contextual transitions, and natural intonation that holds listener attention through completion.

Voice clone technology is also available: editors can use their own voice to deliver articles, creating a personal connection that text alone cannot achieve. Listeners recognize the writer’s voice and develop familiarity with your brand.
