The invention relates to an audio playing method and device. The method comprises the steps of detecting key information in an audio in a process of playing the audio; and highlighting key informationunder the condition of detecting the key information. According to the method and the device, the key information in the audio is highlighted in the process of playing the audio, so in the process ofplaying the audio, a user can hear the key information in the audio timely and clearly, and the user is prevented from missing interested or important content in the process of listening to the audio.

An audio output adjustment method and system thereof, the method comprising the following steps: acquiring the frequency of a current environmental sound and the frequency of a current audio output (S101); determining whether the difference between the frequencies of the audio output and the environmental sound is less than a preset threshold (S102); and if yes, then increasing the frequency of the audio output (S103). The audio output adjustment method and system thereof can automatically adjust an audio output according to environmental noise, such that a user can listen to the content of the audio output as clearly as possible in various kinds of environments without manually adjusting the audio output during audio / video play.

The invention discloses an earphone environmental sound monitoring method and the earphone. The method includes: in the listening mode, acquiring an environmental sound signal; extracting a voice signal from the environmental sound signal; outputting the voice signal to an earphone for playback; and / or removing the voice from the environmental sound signal signal to obtain a noise signal; noise reduction processing is performed on the noise signal to generate a noise reduction signal and output it to the earphone for playback.

The invention belongs to the technical field of public broadcast amplification, in particular to a multi-channel sound amplification system for adjusting the volume of a loudspeaker. The system comprises a plurality of sound amplification subsystems, each sound amplification subsystem corresponds to one channel, and each sound amplification subsystem performs echo cancellation by using the acquired sound signals and the sound source signals in all channels to obtain error signals. According to the obtained error signals, the noise sound pressure level of the current environment is obtained, the volume value of the loudspeaker in the sound amplification subsystem is calculated in combination with a mapping function, and the corresponding volume gain value of the loudspeaker at the current moment is obtained. By multiplying the sound signal to be played picked up from the sound amplification subsystem by the obtained loudspeaker volume gain value at the current moment, the processed sound source signal is obtained, and is played and amplified by the loudspeaker in the sound amplification subsystem.

The present invention is provided with a wireless microphone and a first microphone room, which facilitates the use of the microphone to speak to the surroundings, so that guests can hear their own words clearly, and the wireless microphone is pressed against the wireless microphone through the first microphone room to prevent the wireless microphone from being damaged by collision .

The invention provides a voice communication method and a mobile terminal. The method comprises the steps that after a microphone in the mobile terminal is started, the current communication state of the mobile terminal is judged; if the current communication state is a voice answering state, the uplink amplification gain value of an acoustical signal is adjusted to a first preset gain value; if the current communication state is a voice sending state, the uplink amplification gain value of the acoustical signal is adjusted to a second preset gain value, wherein the first preset gain value is smaller than the second preset gain value. According to the voice communication scheme, high-quality voice communication services can be provided for a user.

The invention discloses an information processing method and an electronic device. The electronic device has a sound collection unit. The sound collection unit acquires first voice data with a volume value of a first volume value, wherein the first voice data corresponds to the first user operating the first electronic device; judging whether the first volume value satisfies a certain Preset condition; when the first volume value satisfies the preset condition, generate and send to the second electronic device a first signal for increasing the output volume of the second sound output unit of the second electronic device Control instruction.

The invention discloses a speech intelligibility algorithm under noise and a train audio playback method and system. The method includes: S101. Acquire noise audio collected by pickups pre-arranged in each car of the train; Audio stream, and do audio stream preprocessing; S102, analyze the noise audio based on the speech intelligibility algorithm under noise as claimed in claim 1; S103, adjust the energy of the speech signal in different frequency bands of the audio stream based on the analysis result of S102 distribution to obtain the audio stream after re-energy equalization; S104, each compartment collects noise audio, and executes S102-103 correspondingly; S105, each audio stream after re-energy equalization establishes a one-to-one correspondence with each compartment. The present application has the effect of enhancing the effect of voice broadcasting in the carriage and improving the experience of passengers.
