Paste your script → choose a preset and voice → generate. LongTTS segments and assembles the full audio automatically.
LongTTS is an AI voiceover desktop app built for long-form text: smart segmentation, automatic synthesis, and complete audio output. 30+ premium voices + adjustable emotion, ready to use and fully offline—your scripts never leave your device.
Supports macOS (Intel / Apple silicon) and Windows 10/11
YouTube explainers, TikTok videos, audiobooks, podcasts, and multilingual learning content—all in one tool.
Smart, sentence-aware segmentation recognizes ellipses, quotations, and abbreviations. Paste anything from an essay to an entire novel and LongTTS processes it in the background, then exports one complete WAV or MP3 file.
Choose from 30+ premium voices, including warm male voices, bright female voices, narrative styles, and multilingual speakers. Fine-tune emotional intensity or upload and record a reference to clone your own voice.
Everything required is included. Models run locally with no internet connection, so your scripts and audio stay on your device and under your control.
A visual workflow with just two essential controls—emotion and speed—plus presets for natural delivery, news, film commentary, and more. Get started in a minute.
A built-in recording studio in Voice Manager: read a short script into your mic with live level monitoring and one-click retakes—no external tools needed to turn a real voice into a reusable voiceover preset.
Generate locally with no usage limits. Choose monthly, annual, or lifetime licensing for personal projects and paid client work.
Listen to real audio generated by LongTTS in different voices and styles. Every sample was synthesized locally with no post-processing.
