Abstract: The invention relates to data processing for sound playing on a sound playing device (DIS), headset or ear bud type, portable by a user in an environment (ENV). The device comprises at least one speaker (HP), at least one microphone (MIC), and a connection to a processing circuit comprising: An input interface (IN) for receiving signals coming at least from the microphone; A processing unit (PROC, MEM) for reading at least one audio content to play on the speaker; and An output interface (OUT) for delivering at least the audio signals to be played by the speaker. The processing unit is arranged for: a) Analyzing the signals coming from the microphone for identifying sounds coming from the environment and corresponding to predetermined classes of target sounds; b) Selecting at least one identified sound, according to a user preference criterion; and c) Building said audio signals to be played by the speaker, by a selected mixing of the audio content and the selected sound.

Abstract: A method for splitting a digital signal using prosodic features included in the signal is provided that includes calculating onset value locations in the signal. The onset values correspond to stress accents in the signal. Moreover, the method includes splitting, using a processor, the signal into a prosodic unit candidate sequence by superimposing the stress accent locations on the signal, and processing the sequence to include only true prosodic units.

Abstract: A method for determining user liveness is provided that includes calculating, by a computing device, a spectral property difference between voice biometric data captured from a user and user record voice biometric data. The user and the computing device constitute a user-computing device pair, and the voice biometric data is captured by the computing device during a verification transaction. Moreover, the method includes inputting the spectral property difference into a machine learning algorithm, calculating an output score with the machine learning algorithm, and determining the voice biometric data was captured from a live user when the output score satisfies a threshold score.
