  • The human voice is still the best way to communicate. And with the KX-TVM50 and KX-TVM200, Panasonic introduces two feature-packed voice processing systems (VPS) designed for efficient communication. The KX-TVM50 and KX-TVM200 each offer automated attendant, automatic call routing, and message notification, and each can be customized to your needs. Other new features include e-mail notification when a caller leaves a message, and the capability to attach voice messages to e-mail messages, easier operation using the LCD on Proprietary Telephones (PT).

  • Signals represent information about data, voice, audio, image, video… There are many ways to classify signals but here we categorize signals as either analog (continuous-time) or digital (discretetime). Signal processing is to use circuits and systems (hardware and software) to act on input signal to give output signal which differs from the input, the way we would like to.

  • Mobile voice-enabled search is emerging as one of the most popular applications abetted by the exponential growth in the number of mobile devices. The automatic speech recognition (ASR) output of the voice query is parsed into several fields. Search is then performed on a text corpus or a database. In order to improve the robustness of the query parser to noise in the ASR output, in this paper, we investigate two different methods to query parsing.

  • This is a demonstration of a voice dialer, implemented as a partially observable Markov decision process (POMDP). A realtime graphical display shows the POMDP’s probability distribution over different possible dialog states, and shows how system output is generated and selected. The system demonstrated here includes several recent advances, including an action selection mechanism which unifies a hand-crafted controller and reinforcement learning. The voice dialer itself is in use today in AT&T Labs and receives daily calls. ...

  • We will demonstrate the ModelTalker Voice Recorder (MT Voice Recorder) – an interface system that lets individuals record and bank a speech database for the creation of a synthetic voice. The system guides users through an automatic calibration process that sets pitch, amplitude, and silence. The system then prompts users with both visual (text-based) and auditory prompts. Each recording is screened for pitch, amplitude and pronunciation and users are given immediate feedback on the acceptability of each recording. ...

  • Signal processing is concerned with the modelling, detection, identification and utilisation of patterns and structures in a signal process. Applications of signal processing methods include audio hifi, digital TV and radio, cellular mobile phones, voice recognition, vision, radar, sonar, geophysical exploration, medical electronics, and in general any system that is concerned with the communication or processing of information.

  • TECHNOLOGIES SUPPORTING VoIP1 In this chapter, we discuss and review various standard and emerging coding, packetization, and transmission technologies that are needed to support voice transmission using the IP technologies. Limitations of the current technologies and some possible extensions or modifications to support high-quality—that is, near-PSTN grade—real-time voice communications services using IP are then presented. VOICE SIGNAL PROCESSING For traditional telephony or voice communications services, the base-band signal between 0.3 and 3.

  • The groundbreaking book Design Driven Testing brings sanity back to the software development process by flipping around the concept of Test Driven Development (TDD)—restoring the concept of using testing to verify a design instead of pretending that unit tests are a replacement for design. Anyone who feels that TDD is “Too Damn Difficult” will appreciate this book. Design Driven Testing shows that, by combining a forward-thinking development process with cutting-edge automation, testing can be a finely targeted, business-driven, rewarding effort.

  • Internet telephony refers to communications services—voice, facsimile, and/or voice-messaging applications—that are transported via the Internet, rather than the public switched telephone network (PSTN). The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet; the process is reversed at the receiving end.

  • CONCLUSIONS AND CHALLENGES1 The technologies and standards required to implement VoIP service are currently well established and mature. Many equipment manufacturers are presently marketing interoperable products—such as IP phones, call servers or managers, MGWs and SGs, and so on—to realize and manage the VoIP service. Advances in digital signal processing and networking software, hardware, and protocol technologies—as discussed in Chapters 2 and 3—have stimulated the development of plug-and-talk-based IP phones.

  • Over the past several decades a need has arisen to enable humans to communicate with machines in order tocontrol their actions or toobtaininformation. Initial attempts at providing human-machine communications led to the development of the keyboard, the mouse, the trackball, the touch screen, and the joy stick. However, none of these communication devices provides the richness or the ease of use of speech which has been the most natural formof communication between humans for tens of centuries. Hence, a need has arisen to provide a voice interface between humans and machines....

  • Work and Employment. Women play an extremely important role in all dimensions of agricultural production. In certain regions, women's time input equals men's, but in other regions traditions restrict their work to the household where they are involved in crop processing (threshing, cleaning, drying, preserving) and also are in charge of most of the household-based activities (water and fuel collection, cooking, cleaning, sewing, tailoring, weaving, and child rearing). Women play an increasingly important role in opium production, livestock production and processing of dairy products.

  • What are the compelling reasons for carrying out dynamic speech modeling? We provide the answer in two related aspects. First, scientific inquiry into the human speech code has been relentlessly pursued for several decades. As an essential carrier of human intelligence and knowledge, speech is the most natural form of human communication. Embedded in the speech code are linguistic (as well as para-linguistic) messages, which are conveyed through four levels of the speech chain.
