How We Built and Grew a Free AI Voice Generator to a 5-Figure MRR Business

TL;DR
We created a web-based AI voice generator that produces realistic, human-like voiceovers in multiple languages and accents. By removing sign-up friction and offering free access, we rapidly grew to 20K+ monthly users worldwide. After launching premium features, we now sustain a 5-figure monthly recurring revenue (MRR). Here’s how.

The Problem
Content creators often struggle with getting fast, affordable, and natural-sounding voiceovers — especially for multiple languages and tones. Hiring voice actors is expensive and time-consuming; existing AI tools often sound robotic.

Our Solution: AccentVoice.net
Instant, no-login access — just enter text and get voice output.

High-quality AI voices that support multiple languages and regional accents.

Tone controls to express emotions like calm, excited, or dramatic.

Fast generation — seconds from text to audio.

We focused on making the experience as seamless and accessible as possible.

Build & Technology
Our small team combined open-source speech synthesis models with custom fine-tuning for emotional and accent nuance. The backend optimizes inference speed to deliver sub-10-second results.

Growth Strategy
Instead of gating access, we launched the core tool 100% free, no registration needed. This drastically lowered user friction and accelerated word-of-mouth.

Within months:

20,000+ monthly active users

Users from 100+ countries

Thousands of creators using our voices in videos, podcasts, and apps

Monetization
We introduced a freemium model offering:

Higher-quality audio exports

Commercial licenses

Early access to new voices

Free tier remains fully usable. Paid upgrades have led to steady 5-figure MRR growth.

Lessons Learned
Remove barriers to use: No sign-up boosted adoption dramatically.

Narrow focus = better product: We focused on voice generation only, ensuring quality.

Listen closely to users: Product improvements came directly from community feedback.

What’s Next?
We’re expanding voice options with regional accents, character voices, and adding API access for developers.
