Patent number: 9190068Abstract: A system and method for using bi-directional conversation data to improve signal presence detection are disclosed. The detector module is adapted to communicate with a signal enhancement module. The detector module collects data from a transmit direction of the connection and a receive direction of a data connection. The collected data from the transmit and the receive direction is used to classify at least one of data in the transmit direction and data in the receive direction. Responsive to the classification, the signal enhancement module enhances data in one of the transmit direction and the receive direction. Hence, data classification accuracy is improved by using data from both the transmit and receive directions. In one embodiment, the detector module applies a voice activity detection module (VAD) process to detect the presence or absence of voice data in the collected data.Type: GrantFiled: April 4, 2011Date of Patent: November 17, 2015Assignee: Ditech Networks, Inc.Inventor: Mahesh Godavarti

Patent number: 8719004Abstract: A system, method and software product punctuates voicemail transcription text. A transcription text of the voicemail message is generated and the pauses between words of the transcribed text are determined. Ellipses are inserted into the transcription text at the position of “er” and “ahh” type words and pauses between words of the transcribed text.Type: GrantFiled: March 19, 2010Date of Patent: May 6, 2014Assignee: Ditech Networks, Inc.Inventor: James Siminoff

Patent number: 8416927Abstract: Methods and systems for limiting voicemail transcription. The methods include answering a forwarded call from a caller to a subscriber of the voicemail transcription service, outputting an audio message to the caller prompting for the caller to leave a voicemail message, recording the voicemail message from audio of the forwarded call, and transcribing the audio of the forwarded call into text. The step of transcribing may be limited according to one or more of the following criteria: the duration of the recording, the number of characters transcribed, the number of text messages generated and filled from transcribed text, the caller ID of the call, the time the call is received, and the duration of the transcription. The systems include a call handler and a transcriber. At least one of the methods may be embodied by a software product including instructions for executing the steps of the method.Type: GrantFiled: April 11, 2008Date of Patent: April 9, 2013Assignee: Ditech Networks, Inc.Inventor: James Siminoff

Patent number: 8301452Abstract: A system and method for retrieving distributed content responsive to voice data are disclosed. Voice data is transmitted from a source client device to media server which applies a mixing table to route the voice data to one or more destinations described by the mixing table. The media server also analyzes the received voice data for one or more events. Responsive to detecting an event, the media server communicates with an application server, which modifies the mixing table so that subsequent data is also routed to a media generator which analyzes voice data received after detection of the event for a command. The media generator communicates with the application server to retrieve data from a user data source, such as a website, associated with a detected command. The media generator produces an audio representation of the retrieved data which is communicated to the source client device via the media server.Type: GrantFiled: August 12, 2009Date of Patent: October 30, 2012Assignee: Ditech Networks, Inc.Inventors: Todd Simpson, Nathan Chandler, Alan Hawrylyshen, Chad Madison, Mike Lambert, Karl Brown

Publication number: 20080240080Abstract: A system and method for providing media-level redundancy in voice-over Internet Protocol (VoIP) systems are disclosed. A central controller receives VoIP calls including a media transmission and call setup data and a standby allocation module included in the central controller transmits the VoIP calls to an active card and a standby card. The active card processes the media transmission of the VoIP call using an array of signal processing modules. The VoIP call setup data is also transmitted to a standby card which stores the call setup data and data identifying the active card processing the VoIP transmission in a profile database. When an active card malfunctions, the central controller transmits an activation signal to the standby card which then loads the contents of the profile database into an array of signal processing modules on the standby card to process the VoIP calls previously processed by the malfunctioning active card.Type: ApplicationFiled: April 2, 2007Publication date: October 2, 2008Applicant: DITECH NETWORKS, INC.Inventor: Abhijit Patait
