  • Publication number: 20100286986
    Abstract: A speech synthesis system can select recorded speech fragments, or acoustic units, from a very large database of acoustic units to produce artificial speech. The selected acoustic units are chosen to minimize a combination of target and concatenation costs for a given sentence. However, as concatenation costs, which are measures of the mismatch between sequential pairs of acoustic units, are expensive to compute, processing can be greatly reduced by pre-computing and aching the concatenation costs. Unfortunately, the number of possible sequential pairs of acoustic units makes such caching prohibitive. However, statistical experiments reveal that while about 85% of the acoustic units are typically used in common speech, less than 1% of the possible sequential pairs of acoustic units occur in practice.

  • Patent number: 7826443
    Abstract: A method for use in an IMS VoIP Network provides for remote troubleshooting of a CPE problem. After receiving a customer complaint, customer care begins the troubleshooting process, collecting and compiling information to send to the test platform. The test platform constructs a SIP test call request instruction and sends it to the CPE. The process is repeated for a number of test calls. If there is no response from any of the test calls, it is concluded that the CPE is in trouble. The results are reported to Customer Care Center, which can use those results to take action to resolve the problem. In another embodiment, after failure of all of the test calls, another SIP instruction is sent to run diagnostics on the CPE. The diagnostic results are reported to Customer Care Center, which can take action based on those results to resolve the problem.

  • Patent number: 7818283
    Abstract: A business process automation system architecture is used to isolate problems in a virtual private network access network. Codified rules and a rules based program are used to determine all equipment from a customer premises equipment to a VPN core access point equipment on a VPN access path and that is associated with a failure. The codified rules also govern the gathering of information on the equipment including determining whether the equipment supports automated diagnostics and the communication protocols used. Extended PING testing is done on the equipment and a status of the extended PING test, link status, line protocol status, and existing loop status is determined. Further testing is automatically run based on the codified rules and the status. The failure is then isolated to the CPE, a local exchange carrier, or a network provider.

  • Patent number: 7800743
    Abstract: A method and apparatus is disclosed for use in fiber optic signature recognition to analyze buried optical fiber to identify a non-threat area along a fiber route and to discontinue monitoring for disturbances along that area of the cable route. The technique includes determining the location of the zone of non-threatening disturbances from comparing an optical signal to the representation of a prearranged optical signal identified as friendly. Once a zone of non-threatening disturbances is identified, all subsequent disturbances in that zone are considered friendly. Cable monitoring is discontinued in the identified zone of non-threatening disturbances so as to avoid monitoring fiber cable when permitted workers are in the area.
