Efficiency of Speech Recognition for Using Interface Design Environments by Novel Designers

چکیده
Previous studies on usability of graphical design-widgets, like menus and buttons, proposed the use of speech and non-speech (earcons and auditory icons) for solving their usability problems. In this paper we investigate speech as an input metaphor to enhance learnability, or the ability to use a system with no prior knowledge, in order to design interfaces using a multimodal interface design toolkit called MMID. Using this toolkit as an experimental platform, the paper presents an empirical multi-group study that compares efficiency of visual-only and multimodal interaction metaphors when used by novel users. Key-Words: interface-design, usability, learnability, experienced performance, efficiency, multimodal interaction, voice-instruction, speech.

Speech Displaces the Graphical Crowd
Developers of visual Interface Design Environments (IDEs), like Microsoft Visual Studio and Java NetBeans, are competing in producing pretty crowded graphical interfaces in order to facilitate completion of interface-design tasks. Previous studies have shown that such interfaces cause the user to experience information overload as well as they create a fertile environment for usability problems...
متن کاملA Database for Automatic Persian Speech Emotion Recognition: Collection, Processing and Evaluation
Abstract Recent developments in robotics automation have motivated researchers to improve the efficiency of interactive systems by making a natural man-machine interaction. Since speech is the most popular method of communication, recognizing human emotions from speech signal becomes a challenging research topic known as Speech Emotion Recognition (SER). In this study, we propose a Persian em...
متن کاملTowards a tool for predicting speech functionality
In these days of multimodal systems and interfaces, many research teams are investigating the purposes for which novel combinations of modalities can be used. It is easy to forget that we still lack solid foundations for evaluating the functionality of individual families of input/output modalities, such as the speech modalities. The reason why these foundations are missing is the complexity of...
متن کاملSpeech Emotion Recognition Based on Power Normalized Cepstral Coefficients in Noisy Conditions
Automatic recognition of speech emotional states in noisy conditions has become an important research topic in the emotional speech recognition area, in recent years. This paper considers the recognition of emotional states via speech in real environments. For this task, we employ the power normalized cepstral coefficients (PNCC) in a speech emotion recognition system. We investigate its perfor...
متن کاملSpeech Emotion Recognition Using Scalogram Based Deep Structure
Speech Emotion Recognition (SER) is an important part of speech-based Human-Computer Interface (HCI) applications. Previous SER methods rely on the extraction of features and training an appropriate classifier. However, most of those features can be affected by emotionally irrelevant factors such as gender, speaking styles and environment. Here, an SER method has been proposed based on a concat...
