Speaker Identification in a Shouted Talking Environment Based on Novel Third-Order Circular Suprasegmental Hidden Markov Models
Ismail Shahin
It is well known that speaker identification yields very high performance in a neutral talking environment, on the other hand, the performance has been sharply declined in a shoute…
Studying and Enhancing Talking Condition Recognition in Stressful and Emotional Talking Environments Based on HMMs, CHMM2s and SPHMMs
Ismail Shahin
The work of this research is devoted to studying and enhancing talking condition recognition in stressful and emotional talking environments (completely two separate environments)…
Talking Condition Identification Using Second-Order Hidden Markov Models
Ismail Shahin
This work focuses on enhancing the performance of text-dependent and speaker-dependent talking condition identification systems using second-order hidden Markov models (HMM2s). Our…
Modeling and Analyzing the Vocal Tract under Normal and Stressful Talking Conditions
Ismail Shahin, Nazeih Botros
In this research, we model and analyze the vocal tract under normal and stressful talking conditions. This research answers the question of the degradation in the recognition perfo…
Speaker Identification in Shouted Talking Environments Based on Novel Third-Order Hidden Markov Models
Ismail Shahin
In this work we propose, implement, and evaluate novel models called Third-Order Hidden Markov Models (HMM3s) to enhance low performance of text-independent speaker identification…
Employing Emotion Cues to Verify Speakers in Emotional Talking Environments
Ismail Shahin
Usually, people talk neutrally in environments where there are no abnormal talking conditions such as stress and emotion. Other emotional conditions that might affect people talkin…
Employing both Gender and Emotion Cues to Enhance Speaker Identification Performance in Emotional Talking Environments
Ismail Shahin
Speaker recognition performance in emotional talking environments is not as high as it is in neutral talking environments. This work focuses on proposing, implementing, and evaluat…
Using Second-Order Hidden Markov Model to Improve Speaker Identification Recognition Performance under Neutral Condition
Ismail Shahin
In this paper, second-order hidden Markov model (HMM2) has been used and implemented to improve the recognition performance of text-dependent speaker identification systems under n…
Speaker Identification Investigation and Analysis in Unbiased and Biased Emotional Talking Environments
Ismail Shahin
This work aims at investigating and analyzing speaker identification in each unbiased and biased emotional talking environments based on a classifier called Suprasegmental Hidden M…
Talking Condition Recognition in Stressful and Emotional Talking Environments Based on CSPHMM2s
Ismail Shahin, Mohammed Nasser Ba-Hutair
This work is aimed at exploiting Second-Order Circular Suprasegmental Hidden Markov Models (CSPHMM2s) as classifiers to enhance talking condition recognition in stressful and emoti…
Employing Second-Order Circular Suprasegmental Hidden Markov Models to Enhance Speaker Identification Performance in Shouted Talking Environments
Ismail Shahin
Speaker identification performance is almost perfect in neutral talking environments; however, the performance is deteriorated significantly in shouted talking environments. This w…
Enhancing speaker identification performance under the shouted talking condition using second-order circular hidden Markov models
Ismail Shahin
It is known that the performance of speaker identification systems is high under the neutral talking condition; however, the performance deteriorates under the shouted talking cond…
Speaker Identification in the Shouted Environment Using Suprasegmental Hidden Markov Models
Ismail Shahin
In this paper, Suprasegmental Hidden Markov Models (SPHMMs) have been used to enhance the recognition performance of text-dependent speaker identification in the shouted environmen…
