Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0043] The inventor found in the research that in the prior art, the reasons why the user cannot fully receive the information in the announced notification voice may include: after the robot dials the user, the user fails to connect to the call due to some reasons, Or, the call is connected after a period of delay, so that the user misses some information in the notification voice.

[0044] The inventor also found in the research that after dialing the user's phone, the user's phon...

Abstract

The invention provides a voice broadcasting method and device, and the method comprises the steps: dialing a user call under the condition that an instruction for dialing the user call is received; detecting signal tones satisfying a preset condition in the signal tones fed back by the user telephone; wherein the preset conditions comprise that the duration is not less than the preset duration andthe frequency obtained through time-frequency conversion is not matched with the preset frequency; wherein the preset frequency refers to the frequency obtained by performing time-frequency conversion on a plurality of preset signal tones of which the dialing state represents a non-connection state; and playing the preset voice under the condition that the signal sound meeting the preset condition is detected. According to the method, the preset voice is played from the angles of the frequencies obtained by performing time-frequency conversion on the signal tones with different dialing statesunder the condition that the signal tones with the dialing states representing connection states are detected. In other words, the preset voice is broadcasted only after the user answers the call, sothat the user can answer the complete information of the preset voice, and the effectiveness of voice broadcasting can be improved.

Description

technical field [0001] The present application relates to the field of voice processing, in particular to a voice broadcast method and device. Background technique [0002] Robots often interact with users through telephone voice at work. For example, when a robot is performing a delivery task, it needs to call the user to pick up the goods after arriving at the target point. [0003] At present, after the robot makes a phone call, it immediately broadcasts the notification voice in a loop. In some cases, the user cannot fully receive the information in the broadcast notification voice, that is, the effectiveness of the voice broadcast is low. Contents of the invention [0004] The present application provides a method and device for playing voice, aiming at solving the problem of low effectiveness of voice broadcasting. [0005] In order to achieve the above object, the application provides the following technical solutions: [0006] The application provides a voice br...
