A method and system for eliminating noise in the channel switching of a simulation telephone

Abstract

The present invention provides a method and system for eliminating noise in the channel switching of an analog telephone. By constructing this method and system in the analog telephone system, the state of platform playback (third-party playback) for the local telephone is identified, and the local default audio (such as comfort noise audio, etc.) is inserted during the gap of platform playback, so as to achieve that the local channel (audio source focus) of the analog telephone does not switch, and avoid the abnormal current noise during the channel switching process.

Description

Technical Field

[0001] The present invention relates to the fields of computer and communication technologies, and particularly to a method and system for eliminating noise in the channel switching of an analog telephone. Background Art

[0002] At present, emerging technologies such as artificial intelligence have gradually matured, and voice artificial intelligence services are also emerging and developing. Voice artificial intelligence services based on traditional analog telephones (landline telephones) have also received extensive attention and initial applications. However, due to the basic requirements and limitations of analog telephone-related systems, during platform playback (third-party playback) during a call, the channel (audio source focus) will switch between the local channel of the telephone (such as the microphone channel of the telephone) and the platform playback channel, resulting in current noise during the channel switching process, causing the end-user of the analog telephone to hear relatively obvious abnormal start-stop playback sounds, which has a greater impact on the user experience. There is a need to invent a new method and system to control channel switching in order to eliminate current noise during analog telephone channel switching and improve the fluency and naturalness during the user's voice interaction process. Summary of the Invention

[0003] The present invention provides a method and system for eliminating noise in the channel switching of an analog telephone. By constructing this method and system in the analog telephone system, the state of platform playback (third-party playback) for the local telephone is identified, and local default audio (such as comfort noise audio, etc.) is inserted during the gap of platform playback, so as to avoid switching the local channel (audio source focus) of the analog telephone and prevent current noise abnormal sounds during the channel switching process. This method and system include control processes related to a third-party playback module and a call and playback management module.

[0004] The third-party playback module is a playback module constructed in the analog telephone system. During a call on the telephone, a specified external or local audio source is played into the sound channel of the telephone in an orderly manner, so that the end-user of the telephone can hear the third-party audio content.

[0005] The call and playback management module monitors the call state of the local telephone and the playback state of the third-party playback module, switches the channel (audio source focus) to the third-party playback channel at the start of the telephone call, and inserts local default audio (such as comfort noise audio, etc.) during the segmented playback gap of the third party, ensuring that the current local playback channel (audio focus) of the telephone does not switch during the segmented playback gap of the third party, and avoiding current noise abnormal sounds during the switching process.

[0006] Main control process: 1) The call and sound playback management module monitors the call status of the phone. When a call is initiated, it immediately notifies the third-party sound playback module to play the default local audio of the phone (such as comfort noise audio, etc.), causing the current sound playback channel (audio source focus) of the phone to switch to the sound playback channel of the third-party sound playback; 2) The call and sound playback management module monitors the third-party sound playback module. When receiving an external sound playback notification, it stops playing the default local audio and instructs the third-party sound playback module to play the external audio. At this time, the current sound playback channel (audio source focus) of the phone continues to remain in the sound playback channel of the third-party sound playback; 3) The third-party sound playback module plays the external audio; 4) When the call and sound playback management module recognizes the end of the external sound playback by the third-party sound playback module, it immediately notifies the third-party sound playback module to play the default local audio of the phone (such as comfort noise audio, etc.), ensuring that after the external sound playback ends, the current sound playback channel (audio source focus) of the phone continues to remain in the sound playback channel of the third-party sound playback; 5) When continuing to receive an external sound playback notification, it returns to step 2) and loops until the call and sound playback end. Description of the Drawings

[0007] Figure 1 It is a method and system structure diagram for eliminating noise in the channel switching of an analog telephone. Detailed Implementation Manner

[0008] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0009] Please refer to Figure 1 , in the embodiments of the present invention, a method and system for eliminating noise in the channel switching of an analog telephone include a third-party sound playback module (1), a call and sound playback management module (2), and a main control process.

[0010] The third-party sound playback module (1) is a sound playback module built into the analog telephone system. During a call on the telephone, it orderly plays the specified external or local audio source into the sound channel of the phone, facilitating the end-user of the phone to hear the third-party audio content.

[0011] The call and sound playback management module (2) monitors the local call status of the phone and the sound playback status of the third-party sound playback module, realizes the switching of the sound channel (audio source focus) to the third-party sound playback channel when the call on the phone starts, and inserts the default local audio of the phone (such as comfort noise audio, etc.) during the segmented sound playback of the third party, ensuring that the current local sound playback channel (audio focus) of the phone does not switch during the segmented sound playback of the third party, and avoiding abnormal current noise during the switching process.

[0012] The main control process is as follows: 1) The call and audio playback management module monitors the call status of the phone. When a call is initiated, it immediately notifies the third-party audio playback module to play the default local audio of the phone (such as comfort noise audio, etc.), causing the current audio playback channel (audio source focus) of the phone to switch to the audio playback channel of the third-party audio playback; 2) The call and audio playback management module monitors the third-party audio playback module. When receiving an external audio playback notification, it stops playing the default local audio and instructs the third-party audio playback module to play the external audio. At this time, the current audio playback channel (audio source focus) of the phone continues to remain in the audio playback channel of the third-party audio playback; 3) The third-party audio playback module plays the external audio; 4) When the call and audio playback management module recognizes the end of the external audio playback by the third-party audio playback module, it immediately notifies the third-party audio playback module to play the default local audio of the phone (such as comfort noise audio, etc.), ensuring that after the external audio playback ends, the current audio playback channel (audio source focus) of the phone continues to remain in the audio playback channel of the third-party audio playback; 5) When receiving an external audio playback notification again, it returns to step 2) and loops until the call and audio playback end.
