How AI Text-to-Speech Works
Traditional text-to-speech systems used concatenative synthesis — stitching together pre-recorded phoneme clips. The result sounded robotic and unnatural, with awkward pauses and flat intonation.
Modern neural TTS is fundamentally different. Deep learning models trained on thousands of hours of human speech learn the patterns of natural language — how pitch rises at the end of questions, how emphasis falls on important words, how pauses create meaning.
MiOffice runs these models on dedicated GPU servers for fast, high-quality synthesis. Your text is processed in seconds, and the generated audio is available for immediate download.
