A production script for interactions between participants and an automated data collection system is created by selectively tuning an experimental script through successive trials until a recognition rate of the system is at least an acceptability threshold. The data collection system uses a semi-constrained grammar, which is a practical accommodation of a larger range of possible inputs than a menu. The data collection system collects data by recognizing utterances from participants in accordan...

A method for controlling a server using voice is disclosed. In one embodiment, a client such as a Web browser is coupled over a data communication channel to a server. A telephone at the client side is connected to an interactive voice response (IVR) system that has a speech recognizer at the server side, over a separate, parallel voice communication channel. The IVR system has a control connection to the server. A table of associations between resource identifiers and network addresses is store...

The present invention relates to system for varying the voice menus and segments presented to the user of a voice response system according to the competence of the user. The response time of a user to voice prompts is measured and an average response time is determined. It is assumed that the lower the average response time, the greater the competence of the user. The average response time is used as an index to a table of ranges of response times. Each range has respective voice segments assoc...

A communication terminal, a communication method and a program thereof capable of easily recording a name and a telephone number of the other party to be called, and easily calling the recorded telephone number by voice. A voice recognizing section recognizes a telephone number output from the directory service and converts a destination name input from a microphone into a format recognizable by the voice recognizing section. The recognized telephone number is associated with the destination nam...

A method for returning a phone call based on information contained in a voicemail message. The method comprises receiving the voicemail message and applying service logic to analyze the voicemail message to extract a spoken phone number included in the voicemail message. The method further comprises associating the extracted phone number with the voicemail message and, in conjunction with retrieving the voicemail message, providing a recipient of the voicemail message with an option to dial the ...

A digital memory used by a digital telephone answering device to record messages, a method by which vacant memory space created by the deletion of a message interlying two saved messages is recovered for future message recording use. Available vacated memory is transferred to the top of memory while saved messages are moved to form a contiguous block in lower memory. The location of messages in the digital memory, and save/delete flag, are stored in an entry table for reference and memory manage...

A local loop access network providing high-speed access at a committed data delivery rate and natural language processing of spoken directory assistance queries. A user's spoken natural language query is processed and a directory assistance database is searched at the network server platform based on the contents of the query. Search results are provided to the user either through an audio interface or as text on a screen. The user is provided with the option of obtaining more information about ...

A method and system in an ISDN network for exchanging call control information between a switch and an IP, and for call set-up and call clearing for intermediate access to an IP. The invention utilizes the User-User Information (UUI) element of the Q.931 messages to exchange call information between a switch and an IP. A subscriber call results in a connection being established to an IP. A request to the IP is encoded in the UUI element of a SETUP message, and call routing information is encoded...

A computer peripheral device for voice and synthesized voice communication is disclosed. The device serves in place of a telephone handset, in a telephone mode of operation, and as a remote-control computer-based media center in a voice control mode of operation, without requiring the use of headphones. Thus the device frees integrated multimedia and voice-command computer control operations from the physical limitations of the workstation, with its keyboard and CRT. The device also integrates t...

A communication system comprising a controller (1) arranged for service implementation. The controller (1) is arranged for extracting a service logical program from a data bank (3) after the controller has received parameters transmitted by a terminal unit (6), and for activating a service in response to a service logical program and second parameters and, in response to a service logical program and first parameters, for providing a service for a subscriber and for transmitting at least one ser...
