What is Free TTS?
Free TTS is an online AI toolkit designed for everyday audio work, covering eight core functions: text-to-speech, speech-to-text, voice separation, voice enhancement, audio editing, audio merging, audio compression, and format conversion. All tools run directly in the browser; basic features are completely free with no subscription required. The cloud-based AI voice service operates on a transparent credit system, allowing users to start with free quotas and purchase additional credits as needed. Files are processed locally by default, while cloud-based AI operations retain data only briefly before automatically deleting it, ensuring privacy and security. The platform supports multiple formats including MP3, WAV, FLAC, OGG, M4A, AAC, and more, enabling batch processing and multi-format exports. With a simple, intuitive interface, users can complete the entire workflow—upload → adjust → export—in just three steps.
Key features
Text-to-Speech: Supports three modes—device-level TTS, local AI TTS, and cloud-based AI voice—enabling the synthesis of natural, highly realistic human voices from text. Ideal for scenarios such as courseware narration, audiobook production, and video voiceovers.
AI Voice Separation: Utilizes deep learning models to automatically separate vocals from accompaniment in songs, producing clean vocal tracks and instrumental tracks. This meets the needs of karaoke practice, remix creation, and extracting educational materials.
