Patent number: 10217461Abstract: A system has multiple audio-enabled devices that communicate with one another over an open microphone mode of communication. When a user says a trigger word, the nearest device validates the trigger word and opens a communication channel with another device. As the user talks, the device receives the speech and generates an audio signal representation that includes the user speech and may additionally include other background or interfering sound from the environment. The device transmits the audio signal to the other device as part of a conversation, while continually analyzing the audio signal to detect when the user stops talking. This analysis may include watching for a lack of speech in the audio signal for a period of time, or an abrupt change in context of the speech (indicating the speech is from another source), or canceling noise or other interfering sound to isolate whether the user is still speaking.Type: GrantFiled: April 26, 2017Date of Patent: February 26, 2019Assignee: Amazon Technologies, Inc.Inventors: Ty Loren Carlson, Rohan Mutagi

Patent number: 7500018Abstract: Techniques for discontinuous transmission (DTX) and fast in-band signaling of configuration changes and protocol messages in speech communications systems provide cost efficiency in terms of radio transmission capacity, in terms of fixed line transmission, and in terms of implementation effort. An exemplary method for performing discontinuous transmission (DTX) in a communications system in which source data is interleaved for transmission from a first component in the system to a second component in the system includes the steps of detecting periods of source data inactivity, and transmitting silence descriptor (SID) frames from the first to the second component during the periods of source data inactivity, certain of the transmitted SID frames being interleaved using a different interleaving algorithm as compared to that used for source data. For example, the source data can be block diagonally interleaved, and certain of the SID frames can be block interleaved.Type: GrantFiled: October 1, 2003Date of Patent: March 3, 2009Assignee: Telefonaktiebolaget L M Ericsson (PUBL)Inventors: Stefan Hakansson, Peter Blocher, Stefan Bruhn, Karl Hellwig

Patent number: 7130309Abstract: A device and method for communication of speech packets over a packet-switched network allows for a greater channel reallocation delay. Initial speech packets may be buffered during a channel reallocation delay and sent through an access medium when a channel is granted. A media access controller may transmit the buffered speech packets through the access medium at a rate exceeding a speech encoding rate. At the receiving user equipment, the initial speech packets are decoded and buffered. Speech signals representative of the initial speech packets may have a shortened time period to compensate at least in part for the channel reallocation delay. Decoded speech packets may be processed using a rate matching process at a rate which initially exceeds the speech encoding rate which may be gradually decreased to approximately the speech encoding rate. The rate matching may include dynamic time warping to substantially preserve attributes of the original speech.Type: GrantFiled: February 20, 2002Date of Patent: October 31, 2006Assignee: Intel CorporationInventor: Boaz Planka

Patent number: 7110416Abstract: Circuitry, embodied in a media subsystem, reproduces a speech or other type of audio signal, and is operable during a time that comfort noise is being generated for storing data from an arriving data packet that contains data representing a beginning of an interval of speech. The circuitry detects that data representing speech has been stored and synchronizes the circuitry to the beginning of the interval of speech by terminating the generation of comfort noise that precedes the interval of speech, and reproduces the speech by decoding the stored data from the data packet and converting the decoded data to an audio speech signal. The arriving data packet contains at least one frame of speech data having a duration of X milliseconds, and the circuitry includes an audio device, such as a DAC or a PCM connection, that requests decoded speech data at a rate given by X/Y milliseconds, where Y is greater than one.Type: GrantFiled: September 4, 2001Date of Patent: September 19, 2006Assignee: Nokia CorporationInventor: Jari Selin

Patent number: 7110380Abstract: A system, method, and computer program product for sharing bandwidth by a plurality of devices in a wireless personal area network or a wireless local area network. A media access control protocol frame includes a beacon signal sent from a coordinator including coordination information to each of the devices of the WPAN, an optional contention access period, and a contention free period that includes an additional shared period that is managed as a slot cycle time division multiple access period, a polling period, or as management period. The coordination information includes a device-unique start time indicator and a transmission duration defining a guaranteed time slot within the contention free period of the frame for each of the networked devices.Type: GrantFiled: February 7, 2002Date of Patent: September 19, 2006Assignee: Freescale Semiconductor, Inc.Inventor: William M.

Patent number: 7080162Abstract: The present invention provides a network interface adapter for connecting a client computer to a computer network that includes a reduced hardware media access controller (MAC) coupled through a physical interface (PHY) to the network physical link. A significant portion of the MAC functionality is implemented as software within the processor of the host client computer. The hardware portion of the preferred MAC implementation provides memory for buffering communications between the PHY and the client computer. The preferred hardware aspects of a MAC in accordance with the present invention also includes a register interface for register-driven communications between the hardware portion of the MAC and the software portions of the MAC implemented within the client computer. By implementing most of the MAC functionality in software within the host computer, the preferred MAC provides lower cost, lower power consumption, and generally greater flexibility.Type: GrantFiled: October 8, 2003Date of Patent: July 18, 2006Assignee: Intel CorporationInventors: Michael R.
