A voice interface for VTLS
… namely, voice recognition system, text-to-speech synthesizer, and screen review program, were identified. These components were selected after a comparative study of several commercially available systems. Once the components were selected they were integrated to form a complete voice …

Real-time speech animation system
… the synthesis procedure of a videorealistic speech animation system [7] to achieve real-time speech animation synthesis. A synthesis rate must be high enough for real-time video streaming for speech animation systems to be viable in industry and deployed as applications for user machine …

The audio-graphical interface to a personal integrated telecommunications system
… machine. Known callers are identified with a speech recognition unit so they can receive personal outgoing recordings. The system's owner accesses messages over the telephone by voice using natural language queries, or with the telephone keypad. Electronic mail messages and system status are …

The effects of speech rate, message repetition, and information placement on synthesized speech intelligibility
Recent improvements in speech technology have made synthetic speech a viable I/O alternative. However, little research has focused on optimizing the various speech parameters which influence system performance. This study examined the effects of speech rate, message repetition, and the placement of …

Assessing human performance trade-offs of a telephone-based information system
… The four factors manipulated were: synthesized speech rate, time available for user input, subject age, and background music level. Subjects searched a fictitious department store database for 16 specific store items and transcribed 16 information messages which were spoken by a computer speech …

Speech Enhancement Using Speech Synthesis Techniques
<p>Traditional speech enhancement systems reduce noise by modifying the noisy signal to make it more like a clean signal, which suffers from two problems: under-suppression of noise and over-suppression of speech. These problems create distortions in enhanced speech and hurt the quality of the …

Reading machines for the blind: a study of federally supported technology development and innovation
… into the information content of articulated speech which later provided a basis for computer-driven speech synthesizers. This first federal program was terminated at the end of the war, but in 1957, Eugene Murphy of the Veterans Administration revived the program as Congress expanded the …

Investigating Prosodic Boundaries
… base file which in turn had been produced by a speech synthesizer, to minimize the amount of variability across tokens. Subjects were then asked to select an interpretation and a confidence rating for each token, which were then combined to result in a weighted response variable. The …

Navigator- A navigation system for the visually impaired
… This system would use voice-to-text and text-to-speech technologies to communicate with the user easily effectively. The system would also give turn-by-turn voice navigation while detecting any obstacles on the way. Two user studies were conducted to better understand these characteristics and …
