Problems solved by technology

However, if you only adjust the side tone volume with reference to the background noise or the volume level of the microphone radio signal, in a very noisy environment, you will need to provide the user with a rather loud side tone, and it may not be possible for the user to hear the test clearly in the noisy environment. sound

Abstract

The invention relates to a communication device and a method for adjusting output sidetone thereof. The method comprises the following steps: receiving far-end sound; receiving a near-end sound to form a sidetone, and obtaining an average input volume of the near-end sound; detecting environmental noise in the near-end sound; analyzing the average noise volume and the noise frequency band of the environmental noise to judge whether the average noise volume of the environmental noise is greater than the average input volume or not; if the average noise volume is greater than the average input volume, performing volume adjustment on a specific frequency band of the sidetone to increase a first gain value to form an adjusted sidetone; wherein the specific frequency band and the noise frequency band of the environmental noise belong to the same frequency band or different frequency bands; and playing the adjusted sidetone and the far-end sound.

Description

technical field [0001] The invention relates to a communication device and a method for adjusting the output side tone, in particular to a communication device which can be adjusted according to the frequency range of external noise and a method for adjusting the output side tone. Background technique [0002] When users communicate in a noisy environment, they often speak louder and louder because they cannot hear their own voice clearly. Generally speaking, the microphone of the communication device is used to pick up the user's speech and play it to the speaker to compensate the user's own voice, which is called side tone (Side Tone). Since the user judges whether he needs to adjust the intensity of his speech by hearing the volume of his own voice, especially when talking in a noisy environment, if the communication device can provide a side tone with an appropriate volume, the user can have a more natural voice. Conversation feeling, to avoid the user talking louder an...
