摘要： The present disclosure relates to systems and methods for providing subtitle for a video. The video's audio is transcribed to obtain caption text for the video. A first machine-trained model identifies sentences in the caption text. A second model identifies intra-sentence breaks with in the sentences identified using the first machine-trained model. Based on the identified sentences and intra-sentence breaks, one or more words in the caption text are grouped into a clip caption to be displayed for a corresponding clip of the video.

摘要： An information processing apparatus includes a processor configured to: acquire first data indicative of a temporal change of an intensity of sound emitted by an apparatus; generate second data by extracting, from the first data, a maximum value in each section of a time width corresponding to temporal resolution at which human voice is unrecognizable and discarding values other than the maximum value; and transmit the second data to an external apparatus.

摘要： An electronic device and method for chronic pulmonary disease prediction from audio input based on short-winded breath determination using artificial intelligence is disclosed. The electronic device receives an audio input associated with a user. The electronic device applies an Artificial Intelligence (AI) model to detect a short-winded breath duration that corresponds to a time duration between an end of a first spoken word and a start of a second spoken word succeeding the first spoken word. The electronic device detects a speaking pattern. The electronic device applies a Recurrent neural network (RNN) model to reconstruct a set of short-winded breath audio samples. The electronic device generates an audio sample dataset and a set of audio features. The electronic device applies a modular neural network model on the generated audio sample dataset and on the generated set of audio features to determine a set of chronic obstructive pulmonary disease (COPD) metrics.

摘要： Methods of assessing the pathological and/or physiological state of a subject, methods of monitoring a subject with heart failure or a subject that has been diagnosed as having or being at risk of having a condition associated with dyspnea and/or fatigue, and methods of diagnosing a subject as having decompensated heart failure are provided. The methods comprise obtaining a voice recording from a word-reading test from the subject, wherein the voice recording is from a word-reading test comprising reading a sequence of words drawn from a set of n words and analysing the voice recording, or a portion thereof. The analysing can comprise identifying a plurality of segments of the voice recording that correspond to single words or syllables; determining the value of one or more metrics selected from the breathing %, unvoicing/voicing ratio, voice pitch and correct word rate at least in part based on the identified segments; and comparing the value of the one or more metrics with one or more respective reference values. Related systems and products are also described.

摘要： A voice/non-voice determination device robust with respect to an acoustic signal in a high-noise environment is provided. The voice/non-voice determination device includes an acoustic scene classification unit including a first model which receives input of an acoustic signal and outputs acoustic scene information which is information regarding a scene where the acoustic signal is collected, a speech enhancement unit including a second model which receives input of the acoustic signal and outputs speech enhancement information which is information regarding the acoustic signal after enhancement, and a voice/non-voice determination unit including a third model which receives input of the acoustic signal, the acoustic scene information and the speech enhancement information and outputs a voice/non-voice label which is information regarding a label of either a speech section or a non-speech section.

摘要： Systems and methods are disclosed. A digitized human vocal expression of a user and digital images are received over a network from a remote device. The digitized human vocal expression is processed to determine characteristics of the human vocal expression, including: pitch, volume, rapidity, a magnitude spectrum identify, and/or pauses in speech. Digital images are received and processed to detect characteristics of the user face, including detecting if any of the following is present: a sagging lip, a crooked smile, uneven eyebrows, and/or facial droop. Using the human vocal expression characteristics and face characteristics, a determination is made as to what action is to be taken. A cepstrum pitch may be determined using an inverse Fourier transform of a logarithm of a spectrum of a human vocal expression signal. The volume may be determined using peak heights in a power spectrum of the human vocal expression.

摘要： An information processing apparatus is connected to a peripheral apparatus that includes sound inputting means for outputting a sound signal representative of sound of surroundings. The information processing apparatus performs control such that, in a case where sound input is required in processing of an application determined in advance, in a state in which a sound signal accepted from the peripheral apparatus is cut off, the sound signal accepted from the peripheral apparatus is accepted and the sound signal is used only in the processing of the application determined in advance.
