Whisper

Speaker identification for whispered speech based on frequency warping and score competition

In certain situations, talkers will intentionally use whisper instead of neutral speech for the sake of privacy or confidentiality, which severely degrades the performance of speaker identification systems trained with only neutral speech. There are considerable differences in the spectral structure between whisper and neutral speech due to an absence of voice harmonic excitation. This study in...

Advancements in whisper-island detection within normally phonated audio streams

In this study, several improvements are proposed for improved whisper-island detection within normally phonated audio streams. Based on our previous study, an improved feature, which is more sensitive to vocal effort change points between whisper and neutral speech, is developed and utilized in vocal effort change point(VECP) detection and vocal effort classification. Evaluation is based on the...

Lipreading approach for isolated digits recognition under whisper and neutral speech

Whisper is a speech production mode normally used to protect confidential information. Given the differences in the acoustic domain, the performance of automatic speech recognition (ASR) systems decreases with whisper speech. An appealing approach to improve the performance is the use of lipreading. This study explores the use of visual features characterizing the lips’ geometry and appearance ...

An entropy based feature for whisper-island detection within audio streams

Non-neutral speech, especially whispered speech, has strong negative impact on speech system performance. It is therefore necessary to detect whisper-islands embedded within neutral speech prior to subsequent processing steps. Detecting whisper-islands in speech audio streams can contribute to improved modeling, speech analysis, and understanding. Speech technology can also benefit by allowing ...

Speaker identification for whispered speech using modified temporal patterns and MFCCs

Speech production variability due to whisper represents a major challenges for effective speech systems. Whisper is used by talkers intentionally in certain circumstances to protect personal privacy. Due to the absence of periodic excitation in the production of whisper, there are considerable differences between neutral and whispered speech in the spectral structure. Therefore, performance of ...
