5 results about "Infrasound" patented technology

It is disclosed a method for operating a Text-to-Speech (TTS) framework (1) with an integrated Intonation-Aware Subsonic Harmonics (ISH) unit (2, 2.1, 2.2, 2.3, 2.4). Said method including a sequence of steps to generate and integrate inaudible subsonic frequencies (f.) with a synthesized speech waveform (g.), and to dynamically adjust them based on modulation parameters (e.) and contextual feedback (c.) derivable from the text inputted to the TTS system (1). This procedure influences prosodic features results in more natural-sounding, fluid, and expressive synthetic speech signal (h.).

A system and method for cardiovascular monitoring and reporting are disclosed. The system (CV monitoring system) includes a data analysis system and an in-ear biosensor system that preferably includes left and right earbuds. The earbuds include infrasound / vibration sensors that detect biosignals from the individual including signals associated with cardiovascular activity (CV signals). The analysis system calculates cardiovascular function measurements (CV function measurements) based upon the CV signals. The CV monitoring system uses machine learning to predict blood pressure (BP) measurements of the individual based upon the CV signals and the calculated CV function measurements. In an embodiment, the CV monitoring system includes an EKG detection system that detects EKG signals associated with heart function. The analysis system can calculate additional CV function measurements from the EKG signals to augment the CV function measurements calculated from the CV signals, and predict BP measurements using the full complement of CV function measurements.

It is disclosed a method for generating an enhanced natural-sounding speech in a Text- to-Speech (TTS) system (1). Said method including a sequence of steps to be executed by an Intonation-Aware Subsonic Harmonics (ISH) unit (2, 2.1, 2.2, 2.3, 2.4), which is integrated with the TTS system (1), in order to generate and integrate inaudible subsonic frequencies (f.) with a synthesized speech waveform (g.), and to dynamically adjust them based on modulation parameters (e.) and contextual feedback (c.) derivable from the text inputted to the TTS system (1). This procedure influences prosodic features results in more natural-sounding, fluid, and expressive synthetic speech signal (h.).

It is disclosed an Intonation-Aware Subsonic Harmonics (ISH) unit (2), adapted to be integrated into a Text-to-Speech (TTS) system (1). Said unit 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.).
