Frequently Asked Questions

What makes this TTS tool special?

We use state-of-the-art Kokoro-82M AI model, ranked #1 in TTS quality benchmarks. It outperforms models 5-15x its size in natural speech synthesis. Plus, it's completely free and works entirely in your browser with no server uploads.

Is my text stored or logged?

No. All processing happens locally in your browser. Your text is never sent to any server. We don't store, log, or track any of your inputs or generated audio. Your privacy is guaranteed.

How much text can I convert at once?

Up to 500 characters per generation. This is the optimal length for fastest and most natural results. For longer content, split it into multiple sections and generate separately.

Which voice sounds best?

af_heart (Female American) and af_bella (Female American) are Grade A quality and sound most natural. All voices are high-quality, so choose based on your preference for gender and accent.

How long does it take to generate speech?

Most text converts in 40-200 milliseconds (under 0.2 seconds). The first time you use the tool, the AI model downloads (~90MB, takes 1-3 minutes depending on internet speed). After that, it's cached for instant use.

Can I use the generated audio commercially?

Yes! Audio generated by this tool is yours to use. You can use it in personal projects, commercial products, videos, and any other use without attribution required.

Does it work on my phone?

Yes! The TTS tool works on all modern smartphones (iOS and Android) with any modern web browser. No app installation needed. Just visit on your phone's browser.

Can I edit the generated audio?

The generated WAV files can be edited in any audio editor like Audacity, Adobe Audition, or similar software. You can trim, adjust volume, add effects, and more.

What if the speech quality sounds robotic?

AI voices may sound slightly artificial to some ears. For best results: use Grade A voices (af_heart/af_bella), keep text length moderate (100-200 characters), and add punctuation to guide prosody (pauses, emphasis).

Why does the first load take longer?

The AI model (~90MB) needs to download on first use. This is cached in your browser, so subsequent uses are instant. Subsequent loads after browser restart may require redownloading.
