Abstract: An online system receives, from a client device of a posting user, a script for a voice-based content item. The online system retrieves a voice synthesis model stored in the user profile of the posting user and generates a synthetic audio stream using the retrieved voice synthesis model and based on the received script. The online system presents the generated synthetic audio stream to the posting user and receives instructions for modifying the synthetic audio stream. The online system generates a second audio stream based on the received instructions and composes the voice-based tent item based on the generated second audio stream.

Abstract: A client device receives an arrangement of at least a subset of participants of a virtual meeting. The client device additionally receives an audio stream for each participant of the subset of participants of the virtual meeting. For each participant of the subset of participants, the client device determines a location based at least in part on the received arrangement, and modulates the received audio stream of the participant based on the determined location. The client device generates a combined modulated audio stream by combining the modulated audio stream of each of the participants and plays the combined modulated audio stream.
