Abstract

In aspects of modulation-based call exit management, a media device detects that a user desires to exit a conference call and determines whether a video feed of the conference call is active or inactive. Based on the video feed being active, the media device applies at least one of modulation or a depth effect to the pre-recorded audio message to generate a modified pre-recorded audio message. Based on the video feed being inactive, the media device records an audio message of the user reading the contextual transcript during the conference call to generate a recorded audio message and applies at least one of the modulation or the depth effect to the recorded audio message to generate a modified recorded audio message. The media device provides the modified pre-recorded audio message or the modified recorded audio message to a speaker that emits the provided audio message.

Claims (60)

1 . A method, comprising:

maintaining a contextual transcript and a pre-recorded audio message;

detecting that a user desires to exit a conference call;

determining that a video feed of the conference call is active or inactive, and one of:

based on the video feed of the conference call being active;

displaying a prompt to generate a modified pre-recorded audio message;

generating the modified pre-recorded audio message by applying at least one of modulation or a depth effect to the pre-recorded audio message to sound like someone other than the user; and

providing the modified pre-recorded audio message to an external speaker that emits the modified pre-recorded audio message; or

based on the video feed of the conference call being inactive:

recording an audio message of the user reading the contextual transcript during the conference call to generate a recorded audio message;

applying at least one of the modulation or the depth effect to the recorded audio message to generate a modified recorded audio message; and

providing the modified recorded audio message to the external speaker that emits the modified recorded audio message.

2 . The method of claim 1 , wherein the detecting includes detecting a gesture of the user that indicates the user desires to exit the conference call.

3 . The method of claim 1 , wherein the detecting includes detecting a comment communicated by the user during the conference call that indicates the user desires to exit the conference call.

4 . The method of claim 1 , wherein the video feed being active includes a camera of a computing device capturing video images of the user.

5 . The method of claim 1 , wherein generating the modified pre-recorded audio message includes selecting the pre-recorded audio message and at least one of the modulation or the depth effect applied to the pre-recorded audio message.

6 . The method of claim 5 , wherein the pre-recorded audio message is a recording of the user reading the contextual transcript before the conference call.

7 . The method of claim 1 , further comprising:

displaying the prompt on a media device instructing the user to look in an indicated direction.

8 . A system, comprising:

a memory to maintain a contextual transcript and a pre-recorded audio message; and

a processor coupled with the memory, the processor configured to cause the system to:

detect that a user desires to exit a conference call;

determine that a video feed of the conference call is active or inactive, and one of:

based on the video feed of the conference call being active:

apply at least one of modulation or a depth effect to the pre-recorded audio message to generate a modified pre-recorded audio message; and

provide the modified pre-recorded audio message to an external speaker that emits the modified pre-recorded audio message; or

based on the video feed of the conference call being inactive:

display a prompt to generate a recorded audio message;

generate the recorded audio message by recording an audio message of the user reading the contextual transcript during the conference call;

apply at least one of the modulation or the depth effect to the recorded audio message to generate a modified recorded audio message that sounds like someone other than the user; and

provide the modified recorded audio message to the external speaker that emits the modified recorded audio message.

9 . The method system of claim 8 , wherein the system is configured to detect a gesture of the user that indicates the user desires to exit the conference call.

10 . The system of claim 8 , wherein the system is configured to detect a comment communicated by the user during the conference call that indicates the user desires to exit the conference call.

11 . The system of claim 8 , wherein the system is configured to display the contextual transcript on a screen.

12 . The system of claim 11 , wherein the system is configured to:

mute the conference call; and

record the audio message of the user while the conference call is muted.

13 . A media device, comprising:

a memory to maintain a contextual transcript and a pre-recorded audio message; and

a processor coupled with the memory, the processor configured to cause the media device to:

detect that a user desires to exit a conference call;

determine whether a video feed of the conference call is active or inactive, and one of:

based on the video feed being active:

apply at least one of modulation or a depth effect to the pre-recorded audio message to generate a modified pre-recorded audio message; and

provide the modified pre-recorded audio message to a speaker that emits the modified pre-recorded audio message; or

based on the video feed being inactive:

record an audio message of the user reading the contextual transcript during the conference call to generate a recorded audio message;

apply at least one of the modulation or the depth effect to the recorded audio message to generate a modified recorded audio message; and

provide the modified recorded audio message to the speaker that emits the modified recorded audio message.

14 . The media device of claim 13 , wherein the processor further causes the media device to detect a gesture of the user that indicates the user desires to exit the conference call.

15 . The media device of claim 13 , wherein the processor further causes the media device to detect a comment communicated by the user during the conference call that indicates the user desires to exit the conference call.

16 . The media device of claim 13 , based on the video feed being active, the processor further causes the media device to display a prompt on at least one of the media device or a computing device that instructs the user to look in an indicated direction in relation to the modified pre-recorded audio message being emitted by the speaker.

17 . The media device of claim 13 , wherein the video feed being active includes a camera of a computing device configured to capture video images of the user.

18 . The media device of claim 13 , wherein based on the video feed being inactive, the processor further causes the media device to display the contextual transcript on a display screen of the media device.

19 . The media device of claim 13 , wherein based on the video feed being inactive, the processor further causes the media device to:

mute the conference call; and

record the audio message of the user while the conference call is muted.

20 . The method of claim 1 , further comprising:

displaying an additional prompt on a media device instructing the user to look in an indicated direction of the modified pre-recorded audio message being emitted by the external speaker.
