Voice activity detector (VAD) for use in an LPC coder in a mobile radio system uses autocorrelation coefficient R 0 , R 1 . . . of the input signal, weighted and combined, to provide a measure M which depends on the power within that part of the spectrum containing no noise, which is thresholded against a variable threshold to provide a speech/no ...

Voice-activated AGC for teleconferencing
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002In a group teleconference, sound pressure levels at the microphone vary due to variations in speaking distances and loudness. The conventional automatic gain control (AGC) appropriately adjusts the microphone gain so as to achieve a constant level. However, due to the lack of discrimination between speech and nonspeech sounds, nonspeech sounds can ...

IEEE Transactions on Consumer Electronics, 1986
Telephones are already widely used in many areas, and various services come into wide use by means of public telephone networks today. The importance of a telephone set has been increasing as an access device to those services. Some telephone have additional functions, for example, automatic dialing, redialing, timer, etc.

VOICE-ACTIVATED QUESTION ANSWERING
2006 IEEE Spoken Language Technology Workshop, 2006Summary form only given. Text-based Question Answering technology has made significant progress in the last few years. Cellular phones are now shipping with integrated web browsers. It is clear the next step is to integrate voice input and output with Question Answering systems to alleviate the keyword bottleneck of cellular phones.

Voice encoder using a voice activity detector
The Journal of the Acoustical Society of America, 1997A voice encoder using a voice activity detector in which two predictive coefficients available from an adaptive predictor in the voice encoder are received for each sample of a input voice signal of the voice encoder. Average values of the predictive coefficients are calculated for each fixed period to decide whether the period is a voice active period

Impassive Support for The Active Voice
JAMA: The Journal of the American Medical Association, 1973To the Editor.— The "virtual ban on the passive voice" is not all that virtual; most experienced medical writers agree that a smooth blending of active and passive voice is often a hallmark of that rare entity, the exquisitely written medical paper—the breed is not quite yet extinct.

Hamlet: a prototype of a voice activated typewriter
European Conference on Speech Technology, 1987This project integrates different parts of a speaker-dependent isolated word voice-activated typewriter on a personal computer (IBM PC-AT). To build up the language model (for French), several routines have been written: automatic grapheme to phoneme conversion, semiautomatic training texts (20 pages) processing (building up the graphemic (2500 words ...

On noise robust voice activity detection
Interspeech 2011, 2011In this paper, we show that the performance of voice activity detection algorithms (VAD) can be highlydependent on the type of background noise and we introduce a new VAD algorithm that is based onrelative energy measurements in different frequency bands.

Voice activated : exploring the effects of voices on behaviours.
2014Decades of priming research have revealed that environmental stimuli feed into our behaviours, often without any awareness of our using this information to guide our behaviour. This has been shown using plentiful stimuli across multiple contexts. One of the most socially rich stimuli in our environment is voice, and yet this has featured surprisingly ...
