AI Text-To-Speech is a versatile desktop application for converting text into natural-sounding speech. It integrates leading cloud providers — ElevenLabs, Azure Cognitive Services, and Google Cloud TTS — alongside local models Bark and Tortoise-TTS for fully offline synthesis. The application supports voice cloning from short audio samples, 50+ languages, emotional tone control, SSML markup for fine-grained prosody, and batch export to MP3, WAV, and OGG formats.
