  • Publication number: 20130197908
    Abstract: Systems and methods for speech processing in telecommunication networks are described. In some embodiments, a method may include receiving speech transmitted over a network, causing the speech to be converted to text, and identifying the speech as predetermined speech in response to the text matching a stored text associated with the predetermined speech. The stored text may have been obtained, for example, by subjecting the predetermined speech to a network impairment condition. The method may further include identifying terms within the text that match terms within the stored text (e.g., despite not being identical to each other), calculating a score between the text and the stored text, and determining that the text matches the stored text in response to the score meeting a threshold value. In some cases, the method may also identify one of a plurality of speeches based on a selected one of a plurality of stored texts.

  • Patent number: 6359976
    Abstract: A system and method for monitoring service quality using Call Detail Records (CDR) in a communications network, such as a Signaling System No. 7 (SS7) network, is disclosed. Network monitors capture substantially all signaling units in the SS7 network generate a complete record for all calls, transactions and other communications over the network. Users configure CDR profiles that are used to filter the records. A CDR application filters the records by parsing out signaling unit components that have been selected by the user in the CDR profile. The selected message components are then formatted into a CDR record, which is sent to an external system that generates certain statistics for the message records and stores the statistics to a database. A report application recalls the statistics from the database and presents statistics in a reporting format configured by the user.
