    Abstract: The present disclosure provides a method for adding realism to synthetic speech. The method includes receiving text (218) that is to be converted into synthetic speech from a mobile device (108). The text (218) may include embedded emoticons indicating a first prosody information and a predefined sound stored in a stored data repository (208). The method also includes identifying a user associated with the text (218) based on a comparison between metadata associated with the text (218) and user profiles stored in the stored data repository (208); retrieving a speech font from a speech data corpus associated with the user stored in the stored data repository (208). The speech font includes a second prosody information and a predefined accent of the user. The method further includes converting the text (218) into synthetic speech based on the retrieved speech font, which is being modulated based on the emoticon.

    Abstract: This disclosure describes a system that uses a virtual audio device system for unified communications (UC) applications between a host device and a plurality of audio devices (100, 130), which includes a host device (108), a plurality of audio devices (104, 106), and a virtual audio device system (124). The host device (108) executes a Unified Communications (UC) application (114) to generate a first audio data stream. The host device (108) is in communication with a microphone (110) and a speaker (112). The plurality of audio devices (104, 106) receive the first audio data stream generated by the host device, where each of the plurality of audio devices (104, 106) generates its own audio data stream. Further, the virtual audio device system (124) establishes a communication channel between the UC application (114) and the plurality of audio devices (104, 106) based on the plurality of audio devices (104, 106) connected to the host device (108). And, the virtual audio device system (124) is configured to combine the first audio data stream and the additional audio data streams to create a composite audio data stream.
