For example, the audio data may be analyzed to identify language register of a selected speaker, such as the language register of a wearer of a wearable audio sensor, of a speaker engaged in conversation with the wearer of the wearable audio sensor, and so forth. For example, the audio data may be analyzed to obtain textual information, and the textual information may be analyzed to identify the language register. Feedbacks and reports may be provided based on the identified language register.

System and method for assessing speaker spatial orientation are provided. For example, audio data, as well as input from other sensors, may be analyzed to assess speaker spatial orientation. For example, the audio data may be analyzed to determine that two speakers are engaged in conversation. relative direction of one speaker with respect to the other may be obtained. Spatial orientation of at least one of the speakers may be obtained. The spatial orientation may be assessed according to the relative direction and the determination that the two speakers are engaged in conversation. Feedbacks and reports may be provided based on the assessed speaker spatial orientation.

Disclosed herein are apparatus, devices, and methods for monitoring marine animals, such as whales, and other marine mammals, and fish groups within a marine environment. A marine animal monitoring system may include an acoustic receiver array having a high-resolution directional sensing capacity using large-aperture densely-sampled coherent ocean acoustic receiver arrays operative to enhance detection range and localization accuracy of marine mammal vocalizations and fish acoustic signals. The acoustic receiver array may generate acoustic signal information based on acoustic signals sensed at the array. The marine monitoring system may operate to generate marine animal information based on the acoustic signal information, such as marine animal location, species, call type, and/or the like.

An electroacoustic transducer includes: a diaphragm including a cone portion having a conical shape such as a circular conical surface shape or an oval conical surface shape, and a wing-pair portion having a pair of longitudinal split tubular surfaces arranged next to each other, a valley being formed between a side portion of one of the longitudinal split tubular surfaces and a side portion of the other of the longitudinal split tubular surfaces; a converter that performs conversion between vibration of the diaphragm along an axis of the cone portion and an electric signal corresponding to the vibration; and a supporter that supports the diaphragm such that the diaphragm is movable in an axial direction of the cone portion. The small-diameter-side end portion of the cone portion, and a bottom portion of a valley of the wing-pair portion are secured to the converter.

Audio signal processing methods, systems, terminal devices, conference devices, teaching devices, intelligent vehicle-mounted devices, server device, and computer-readable storage media are provided. The method comprises: obtaining current audio signals acquired by a microphone array, the microphone array comprising at least two microphones; generating, according to phase difference information of the current audio signals acquired by the at least two microphones, current sound source spatial distribution information corresponding to the current audio signals; and according to the current sound source spatial distribution information, in combination with the conversion relationship between single speech and overlapping speech learned on the basis of historical audio signals, identifying whether the current audio signals are overlapping speech.

A method of mixing microphone signals. First and second microphone signals are obtained from respective first and second microphones. In at least one affected subband, the first and second microphone signals are mixed to produce first and second mixed signals. At least one reference subband of the first and second microphone signals is processed in order to identify a binaural cue between the first and second microphone signals, the reference subband being distinct from the or each affected subband. The affected subband in the first and second mixed signals is modified in order to re-emphasize the identified binaural cue.
