Abstract

It is disclosed a Text-to-Speech (TTS) system (1) with an Intonation-Aware Subsonic Harmonics (ISH) unit (2) integrated. Said unit (2) being comprised by an Intonation Learning Module (2.2), a Subsonic Harmonics Module (2.3), and a Contextual Feedback Module (2.3). More precisely, the Intonation Learning Module is able to learn the relationship between subsonic harmonic profiles and intonation patterns across various emotional and contextual scenarios. The Subsonic Harmonics Module generates and integrates inaudible subsonic frequencies with a synthesized speech waveform (g.), dynamically adjusting them based on the Intonation Learning Module's output and contextual feedback (c.) on contextual information derivable from the text inputted to the TTS system, given by the Contextual Feedback Module. This procedure influences prosodic features results in more natural-sounding, fluid, and expressive synthetic speech signal (h.)
