A challenge for speech recognition for voice-controlled household devices, like the Amazon Echo or Google Home, is robustness against interfering background speech. Formulated as a far-field speech recognition problem, another person or media device in proximity can produce background speech that can interfere with the device-directed speech. We expand on our previous work on device-directed sp...

In this paper we present a standards-based architecture that enables ubiquitous access to distributed speech and multimodal services. Motorola's “Seamless Mobility” initiatives are focused on giving people continuity of services regardless of context, location, device, or type of network connectivity. Speech technology is a key aspect of seamless mobility: not only does it make it easier to ent...

Modern eye tracking technology allows an observer’s gaze to be determined in realtime by measuring their eye movements. Recent studies have examined the viability of using gaze data as a means of controlling computer games. This paper investigates the combination of gaze and voice recognition as a means of hands-free interaction in 3D virtual environments. A novel game evaluation framework is i...

we addressed the problem of remove the non-voice disturbance in speech recognition. It is always a big problem that the system will wrongly recognize our natural sound, like cough, breath, or sound of lip, nose as speech input and give “recognized ” words output, when we use a speech recognition system. As we know, such non-voice speech is unavoidable for natural speaking, and if we don’t suppl...

Two kinds of typical activated carbons (coal based AC and coconut shell based AC) were modified in a flow of N2 gas has been carried out using a microwave device operating at 2450 MHz and different input power, instead of a conventional furnace. The samples were analyzed by means of low temperature N2 adsorption, elemental analysis and Boehm titration. The results show that microwave heating is...

The scientific bases for human-machine communication by voice are in the fields of psychology, linguistics, acoustics, signal processing, computer science, and integrated circuit technology. The purpose of this paper is to highlight the basic scientific and technological issues in human-machine communication by voice and to point out areas of future research opportunity. The discussion is organ...

since a high toxicity of cyanide which use as a reagent in the gold processing plant, thiosulfate has been recognized as a environmental friendly reagent for leaching of gold from ore. after gold leaching process it's important for recovery of gold from solution using adsorption or extraction methods, one of these methods is activated carbon.the loading of gold from industrial thiosulfate solut...

BACKGROUND A newly developed artificial voice source was clinically evaluated in laryngectomized women for voice quality improvements. The prosthesis was placed in a commercially available, tracheoesophageal shunt valve. METHODS In 17 subjects, voice-producing element (VPE) prototypes were compared with the subject's regular tracheo-esophageal shunt voice in a randomized cross-over trial. The...

An AAL2 link transmission scheme is considered as a promising bandwidth-efficient voice/data transmission method in BS-BSC links of third generation radio access networks. To guarantee low delay requirement of voice traffic, voice delay restriction methods are introduced in the AAL2 link transmission scheme. That is, a timer is used in the loading of voice ATM cell payload for limiting cell pac...
