Embodiments provide a method and system for audio generation from contextual text input is provided. The disclosure gives due importance to the granularity of the content. The system allows the user to specify the properties of the audio to be generated. Here, context is used to identify the importance of a particular sound over the others and thus automatic adjustments of the audio output to give a more realistic feel. The system generates dataset for training audio models. The user can give input query in natural language and the audio requested will be generated for training and developing the necessary classification or other necessary audio models. The system provides a feature of automated fine-tuning of the model parameters to suit the new automatically collected training data. Furthermore, the system provides a pre-trained inbuilt model repository with audio models belonging to the main categories of noises.

The invention discloses an electronic sound signaling system that generates warning sounds in the forward and reverse mode of operation of a vehicle. The signaling system incorporates an electronic circuit with a standard automotive horn or alarm device in place of mechanical contacts or circuit breakers. The electronic circuitry includes electronically powered programmable microcontroller, a horn driver circuit, voltage sensing circuit, on a printed circuit board (PCB) Assembly and one or more sensors. The sound signaling system uses the standard automotive horn device to generate warning sounds in response to one or more sensor signals. The system also performs multiple functions and is compatible to operate in different voltage ranges. The system has many advantages, including increased reliability, increased operating voltage range, reduced circuit complexity, reduced cost and reduced ambient noise.

Disclosed herein are systems and methods for presenting an audio signal associated with presentation of a virtual object colliding with a surface. The virtual object and the surface may be associated with a mixed reality environment. Generation of the audio signal may be based on at least one of an audio stream from a microphone and a video stream form a sensor. In some embodiments, the collision between the virtual object and the surface is associated with a footstep on the surface.

The information processing device includes an acquisition unit, a determination unit, and a signal processing unit. The acquisition unit acquires one or a plurality of other sound elements. The determination unit determines importance levels of the sound elements acquired by the acquisition unit. The signal processing unit changes a sound source position of at least one of a sound element of a content being reproduced or another sound element according to the importance levels of the sound elements determined by the determination unit. Consequently, even in a case where the sound element of the reproduced content and the another sound element are simultaneously generated, sound interference between the sound element of the reproduced content and the another sound element can be suppressed.

Techniques (methods and devices) for audio content serving and creation based on modulation characteristics are disclosed. The techniques include receiving user-associated data related to a user; determining one or more desired modulation characteristic values based on the user-associated data; obtaining a set of one or more target audio tracks, wherein each target audio track represents at least one or more modulation characteristic values; comparing the desired modulation characteristic values with the modulation characteristic values of at least one target audio track from the set of one or more target audio tracks; selecting a target audio track from the at least one target audio track based on the comparing, wherein the modulation characteristic values of the target audio track substantially match the desired modulation characteristic values; and playing the target audio track.
