Abstract: A method for phoneme identification. The method includes receiving an audio signal from a speaker, performing initial processing comprising filtering the audio signal to remove audio features, the initial processing resulting in a modified audio signal, transmitting the modified audio signal to a phoneme identification method and a phoneme replacement method to further process the modified audio signal, and transmitting the modified audio signal to a speaker. Also, a system for identifying and processing audio signals. The system includes at least one speaker, at least one microphone, and at least one processor, wherein the processor processes audio signals received using a method for phoneme replacement.

Abstract: Modulating packetized audio signals in a voice activated data packet based computer network environment is provided. A system can receive audio signals detected by a microphone of a device. The system can parse the audio signal to identify trigger keyword and request, and generate a first action data structure. The system can identify a content item object based on the trigger keyword, and generate an output signal comprising a first portion corresponding to the first action data structure and a second portion corresponding to the content item object. The system can apply a modulation to the first or second portion of the output signal, and transmit the modulated output signal to the device.

Abstract: A method includes detecting whether there is a very short pitch lag in a speech or audio signal that is shorter than a conventional minimum pitch limitation using a combination of time domain and frequency domain pitch detection techniques. The pitch detection techniques include using pitch correlations in a time domain and detecting a lack of low frequency energy in the speech or audio signal in a frequency domain. The detected very short pitch lag is coded using a pitch range from a predetermined minimum very short pitch limitation that is smaller than the conventional minimum pitch limitation.

Abstract: A system may include a wearable camera configured to capture images and a microphone configured to capture sounds. The system may also include a processor programmed to receive the images; identify a representation of one or more individuals in the images; receive from the microphone a first audio signal associated with a voice; determine, based on analysis of the images, that the first audio signal is not associated with a voice of any of the one or more individuals; receive from the microphone a second audio signal associated with a voice; determine, based on analysis of the images, that the second audio signal is associated with a voice of one of the one or more individuals; and cause a first amplification of the first audio signal and a second amplification of the second audio signal. The first amplification may differ from the second amplification in one aspect.

Abstract: An output apparatus according to the present application includes a prediction unit and an output unit. The prediction unit predicts whether or not waveform information having a predetermined context is generated on the basis of detection information detected by a predetermined detection device. The output unit outputs waveform information having an opposite phase to the waveform information having the predetermined context in a case where it has been predicted that the waveform information having the predetermined context is generated.

Abstract: Audio translation system includes a feature extractor and a style transfer machine learning model. The feature extractor generates for each of a plurality of source voice files one or more source voice parameters encoded as a collection of source feature vectors, and generates for each of a plurality of target voice files one or more target voice parameters encoded as a collection of target feature vectors. The style transfer machine learning model trained on the collection of source feature vectors for the plurality of source voice files and the collection of target feature vectors for the plurality of target voice files to generate a style transformed feature vector.
