Zinox Speech — AI Text to Speech Voice Generator

AI text to speech: convert text to voice with 16 natural voices, WAV export, 100% on-device. Neural TTS in your side panel.

Zinox Speech is an AI voice generator and text to speech extension for Chrome that converts text to voice in seconds: a neural text to speech reader that will read text out loud with 16 natural AI voices. It is a fully on-device text to speech AI — a TTS engine that runs in your side panel, needs no account or API key, works offline, and exports any pasted text as text to audio in WAV. No sign-up. No API keys. No uploads to the cloud. The neural voice generator runs entirely on your device. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎙️ 16 NATURAL AI VOICES A full AI voice generator built in, not a robotic system voice from 1995: • American and British voices — female and male • Quality-graded voices, so you always know which one sounds best • Voices tuned for very different jobs: crisp newsroom narration, soft and calm audiobook reading, energetic promo, warm storytelling, confident corporate presentation • Pick a voice, press Generate, hear the result Whether you need a single narrator for a long text or a character voice for a short clip, the voice generator covers it. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📖 TEXT TO SPEECH READER FOR ANY TEXT Use it as a text to speech reader whenever reading is not practical: • Read text out loud from long articles, blog posts and documentation • Read aloud text from notes, study materials and course transcripts • Turn a script or manuscript into an audio draft to check the pacing • Proofread by ear — repeated words and clunky sentences are far easier to catch when you hear them • Multitask: listen while walking, cooking, commuting or training Paste up to 1,500 characters per run. Long passages are automatically split into sentence-level segments and stitched back together seamlessly, so the speech flows without awkward gaps or cut-off words. The extension does not grab text from the page for you — copy the text you want and paste it into the field. That keeps the extension permission-light and your browsing untouched. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎚️ CONTROL HOW IT SOUNDS • Speaking speed from 0.5× to 1.5× — slow down for language learners, speed up for skimming • 24 kHz high-quality audio output • Instant playback right in the panel • Waveform view with a live position indicator, so you can see what you hear • Simple, focused interface: text field, voice picker, speed slider, one button ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 PRIVACY FIRST — 100% ON-DEVICE Most text to speech software sends your text to a server. This one does not. • All neural inference runs locally in your browser • Your text never leaves your device • No accounts, no tracking of your content, no cloud storage of what you type • Works offline once the model has been downloaded • Ideal for confidential notes, internal drafts, personal manuscripts and anything you would not paste into a random website ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🛠️ HOW IT WORKS 1. Open the side panel from the toolbar. 2. Paste or type your text, or load a built-in sample. 3. Choose an AI voice and set the speaking speed. 4. Press Generate Speech — the text to speech AI synthesizes it on your device. 5. Listen, then download the WAV if you want to keep it. First run downloads the neural engine (Kokoro-82M, about 90 MB) plus the ONNX Runtime WebAssembly binary (about 21 MB) from their public CDNs. Everything is cached by the browser afterwards, so later runs start instantly and work offline. Please allow a moment and a stable connection for that very first generation. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 👥 WHO IS IT FOR • Students and researchers who want to read aloud text from dense material • Writers and editors proofreading by ear • Content creators needing a quick AI voice over for a draft video • Podcasters testing a script before recording • Teachers and course authors building accessible materials • Developers who need a fast text to audio converter for UI copy checks • Anyone who simply wants a lightweight text to speech app in the browser
