Noisy Speech Intelligibility Enhancement
This paper addresses the study of the speech intelligibility enhancement. The speech model, noise sources, perceptual aspects of speech, and performance evaluation are reviewed. The intelligibility enhancement system based on spectral subtraction technique is investigated. Spectral density estimation device based on the algorithm of smoothed periodograms is analysed. Determination of the silenc...
متن کاملRephrasing-based speech intelligibility enhancement
Existing algorithms for improving speech intelligibility in a noisy environment generally focus on modifying the acoustic features of live, recorded or synthesized speech while preserving the phonetic composition (the message). In this paper, we present an algorithm for text-to-speech systems that operates at a higher level of abstraction, the message-level. We use a paraphrasing system to adju...
متن کاملIntelligibility enhancement of synthetic speech in noise
Speech technology can facilitate human-machine interaction and create new communication interfaces. Text-To-Speech (TTS) systems provide speech output for dialogue, notification and reading applications as well as personalized voices for people that have lost the use of their own. TTS systems are built to produce synthetic voices that should sound as natural, expressive and intelligible as poss...
متن کاملIntelligibility Enhancement of Speech in Noise
To maintain communication success, humans change the way they speak and hear according to many factors, like the age, gender, native language and social relationship between talker and listener. Other factors are dictated by how communication takes place, such as environmental factors like an active competing speaker or limitations on the communication channel. As in natural interaction, we exp...
متن کاملEffects of enhancement of spectral changes on speech quality and subjective speech intelligibility
Most information in speech is carried in the spectral changes over time, rather than in static spectral shape per se. The present study presents a preliminary assessment of the possible benefits for speech intelligibility of enhancing spectral changes across time, using behavioral tests with both normal-hearing and hearing-impaired subjects. Ratings of speech quality and intelligibility were ob...
