Abstract: A computer-implemented technique can include establishing an audio communication session between first and second computing devices and obtaining, by the first computing device, an audio input signal using audio data captured by a microphone. The first computing device can analyze the audio input signal to detect a speech input by its first user and can determine a duration of a detection period from when the audio input signal was obtained until the analyzing has completed. The first computing device can then transmit, to the second computing device, (i) a portion of the audio input signal beginning at a start of the speech input and (ii) the detection period duration, wherein receipt of the portion of the audio input signal and the detection period duration causes the second computing device to accelerate playback of the portion of the audio input signal to compensate for the detection period duration.

Abstract: Systems, methods and computer readable media for persistent conversations are described. In some implementations, a method can include receiving a communication message sent from a first user to at least one other user and generating a persistent conversation object having a conversation content section and conversation state information. The method can also include storing the communication message in the conversation content section of the persistent conversation object and forwarding the communication message to the at least one other user. The method can further include updating the conversation state information to reflect the receiving, storing and forwarding of the communication message.

Abstract: A computer-implemented technique can include joining, by a computing device having one or more processors, a conference session hosted by a server via a wireless computing network. In response to joining the conference session, the computing device can receive, from the server via the wireless computing network, a dial-in telephone number for reconnecting to the conference session. The computing device can detect a trigger condition indicative of a need to reconnect to the conference session via a cellular telephone network. In response to detecting the trigger condition, the computing device can initiate a telephone call to the dial-in telephone number via the cellular telephone network. In response to the server obtaining authentication of a caller identification of the computing device, the computing device can rejoin the conference session via the cellular telephone network.

Abstract: Implementations generally relate to indicating sound quality during a conference, thereby providing real-time feedback to those generating audio intentionally or unintentionally. In some implementations, a method includes detecting an audio signal during a conference. The method further includes determining one or more sound types in the audio signal based on one or more respective characteristic criteria. The method further includes providing an indicator based on the one or more sounds types.

Abstract: A server-implemented technique can include obtaining external context parameters indicative of an external context of a video chat session, calculating an abuse score based on the external context parameters, the abuse score being indicative of a likelihood the video chat session is abusive, and comparing the abuse score to an abuse score threshold. When the abuse score exceeds an abuse score threshold, the server can transmit, to a reviewer computing device, a request for a human reviewer to review a recorded portion of the video chat session for abuse. When the reviewer computing device returns a response indicating that the human reviewer deemed the video chat session to be abusive, the server can modify a profile of a participant in the abusive video chat session to obtain a modified profile, and generate an output based on the modified profile.

Abstract: A computer-implemented technique can include receiving, at a server from an inviter computing device associated with an inviter user, a request to have a communication session with a plurality of invitee users at a scheduled time. The technique can include determining a time zone of each invitee user, and determining that a specific time zone of a specific invitee user differs by more than a predetermined amount from the time zone of the inviter user. The technique can include providing a time-shifted invitation to a specific invitee computing device associated with the specific invitee user, the time-shifted invitation being for a delayed time that is appropriate for the specific invitee user. The technique can also include receiving an audio/video communication stream corresponding to the communication session beginning at the scheduled time, and providing the audio/video communication stream to the specific invitee computing device at the delayed time.
