A biological sound sensor to be used in contact with a skin of a living body, and includes a casing that has an opening in a face on the side facing the skin of the living body, a double-sided adhesive membrane having a first surface and a second surface, the second surface closes the opening by adhering to the face of the casing and the first surface adheres to the skin when collecting a biological sound produced in the living body. A microphone is arranged in the casing and picks up the biological sound. The double-sided adhesive membrane has a one-material portion, made of the first adhesive material, through the double-sided adhesive membrane from the first surface to the second surface.

A headset main body includes a PTT switch, bone conduction speakers, a first connector to be coupled with a microphone, and a second connector to be coupled with a transceiver. A sleeve of the first connector is coupled to a sleeve of the second connector. A ring of the first connector is coupled to a ground. A chip of the first connector is coupled to a ring of the second connector, and the chip of the first connector is further coupled, via the PTT switch, to the ground.

A system for monitoring dietary activity of a user includes a wearable device having at least one audio input unit configured to record an audio sample corresponding to audio from a user's neck. The system further includes a processor configured to execute programmed instructions stored in a memory to obtain an audio sample from the audio input unit of a wearable device, determine segmental feature values of a set of selected features from the audio sample by extracting short-term features in the set of selected features from the audio sample and determining the segmental feature values of the set of selected features from the extracted short-term features. The processor is further configured to, using a classifier, classify a dietary activity based on the determined segmental feature values of the audio sample and generate an output corresponding to the classified dietary activity.

A throat microphone system and method are disclosed. Certain people may have difficulty vocalizing, such as those suffering from neurodegenerative diseases. The throat microphone system includes a microphone unit that wirelessly communicates with an external device, such as a receiver unit in combination with a smartphone or a smartphone. The microphone unit includes a microphone and a wireless transceiver to wirelessly transmit sound data generated by the microphone. The smartphone processes the sound data in order to increase the intelligibility and/or the volume. Further, the microphone unit may attach to the neck of the wearer and may encircle the neck less than the entire perimeter of the neck. In this way, the microphone unit may be easily removed in the event the wearer is in distress. Moreover, the throat microphone system may include a non-audio sensor, such as a vibration sensor or an electromyograph sensor, in order to determine whether the wearer is voicing speech.

A sub-vocal speech recognition (SVSR) apparatus includes a headset that is worn over an ear and electromyography (EMG) electrodes and an Inertial Measurement Unit (IMU) in contact with a user's skin in a position over the neck, under the chin and behind the ear. When a user speaks or mouths words, the EMG and IMU signals are recorded by sensors and amplified and filtered, before being divided in multi-millisecond time windows. These time windows are then transmitted to the interface computing device for Mel Frequency Cepstral Coefficients (MFCC) conversion into aggregated vector representation (AVR). The AVR is the input to the SVSR system, which utilizes a neural network, CTC function, and language model to classify the phoneme. The phonemes are then combined into words and sent back to the interface computing device, where they are played either as audible output, such as from a speaker, or non-audible output, such as text.

The present disclosure relates to electrolarynx devices, systems, and their use. In particular, the present disclosure relates to methods and compositions (e.g., devices) that provide electrolarynx (EL) users with improved speech quality.
