Abstract: A unified messaging system includes a voice gateway server coupled to an electronics mail system and a private branch exchange (PBX). The voice gateway server provides voice messaging services to a set of subscribers. Within the voice gateway server, a trigraph analyzer sequentially examines 3-character combinations within a text message; determines occurrence frequencies for the character combinations; compares the occurrence frequencies with reference occurrence statistics modeled from text samples written in particular languages; and generates a language identifier and a likelihood value for the text message. Based upon the language identifier, a message inquiry unit selects an appropriate text-to-speech engine for converting the text message into computer-generated speech that is played to a subscriber.

Abstract: A unified messaging system selectively provides voice messages and computer-generated speech messages to a set of subscribers. The unified messaging system includes a voice gateway server coupled to an electronics mail system and a private branch exchange (PBX). In addition, the unified messaging system is configured for determining if a received message is a text message from the electronic mail system or a voice message from the PBX. The voice gateway server preferably includes a trigraph analyzer. When a subscriber selects review of a received message that includes a text message, the trigraph analyzer sequentially examines 3-character combinations within the text message; determines occurrence frequencies for the character combinations; compares the occurrence frequencies with reference occurrence statistics modeled from text samples written in particular languages; and generates a language identifier and a likelihood value for the text message.

Abstract: A voice messaging system with non-user outcalling and auto-provisioning capabilities including an automatic means for configuring a telephone number to become a subscriber to a voice messaging service. The voice messaging system of the present invention facilitates the process of acquiring a voice mailbox by providing non-user outcalling and auto-provisioning. A voice messaging service user will be able to send a non-user voice messages using the voice messaging service, and, the non-user recipient desiring to subscribe to voice mailbox service can acquire a voice mailbox simply by responding to interactive queries after the reception of the voice message. The system also automatically establishes call forwarding at the appropriate central office switch and automatically creates a voice mailbox at the voice messaging system if a non-user recipient desires to become a subscriber to the voice messaging system.

Abstract: In a computer network having a plurality of interconnected terminals and a shared memory device for storing digital data, a message handling system for sending and retrieving both voice and text messages over the computer network. A voice message is input either through a phone associated with one of the computer terminals or via a remote phone. The voice message is converted into a digital voice file which is stored on the shared memory device corresponding to the intended recipient's mailbox. Thereby, one mailbox can contain both voice and text messages. The same message handling mechanism is used for handling both voice and text messages. A list of the messages currently stored for each mailbox can be pulled for display by their respective terminals. A selected voice message may be selected for playback over the phone. Likewise, a text message may be selected for display by the terminal. Call answering and remote playback functions are also provided.
